New website for the New Year

On the 5th December the Minister for Culture, Heritage & the Gaeltacht, Josepha Madigan, TD formally launched the Chester Beatty’s new website. As our followers will know, we have been celebrating the 50th anniversary of Beatty’s extraordinary gift to the nation with a programme of events throughout 2018. The unveiling of the new website was the exciting finale of the year.

Website Launch

Minister Josepha Madigan, TD launching the new Chester Beatty website and digital collections.

For the first time 10% of the extraordinary collections are now available to view digitally online. This is a significant event in the history of the museum, as it now allows visitors to the site to experience the breadth and diversity of the Chester Beatty collections, all now available on open access.

The Conservation blog is an integral part of the new website and from today can be found here. We will post our first blog from this new platform later today. We plan to archive all our past blogs on the new site in January, but sadly for now this will be our last blog posting from this site.

The Conservation Team would like to wish all of our followers a very Happy Christmas and Peaceful New Year. Thank you for all your support and we do hope you’ll continue to track our activities and adventures on the new Chester Beatty website in 2019.

Warriors, Weapons and Horses: conserving folios from a Mamluk manuscript

The Mamluks ruled Syria and Egypt from 1250 until they were defeated by the Ottoman’s in 1517. Very few illustrated manuscripts from this era have survived, but one of them is held at the Chester Beatty. This bound manuscript (CBL Ar 5655), dating from the mid-14th century, is a Compendium of Military Arts featuring warfare, weaponry and horsemanship.  Twelve separate folios from the manuscript have recently been conserved in preparation for our upcoming temporary exhibition, Gift of a Lifetime (opening on 19th October 2018).

The thickly applied white pigment (probably lead white) on the faces and turbans of the warriors had suffered serious cracking and in some cases small losses. In other more localised areas there was cracking and slight flaking/powdering of some pigments, particularly in association with creases in the paper. It is also likely that the smooth surface of the highly burnished paper support had contributed to the loss of media.

Fig 2

Left: Cracking of media associated with creases in the paper (CBL Ar 5655.134); Right: Flaking white pigment (CBL Ar 5655.134).

All of the pigments were checked under magnification and consolidated as needed using Bermocoll, a synthetic cellulose-based adhesive. Isopropanol was applied to the edge of the flaking areas using a very fine brush, directly followed by the adhesive applied with a second brush. The alcohol acts as a wetting agent, reducing the surface tension of the adhesive so it is drawn underneath the flaking pigment layer by capillary action. On drying, the adhesive secures the fragile pigment layer to the paper below.

On a number of folios the paper along the spine edge was fragile and torn with paper fibres at risk of being lost. A small number of tears along the creases in the paper were also apparent. The folios had been repaired in the past and although these historic repairs were indiscreet it was decided that they should be left intact because they had not caused any damage to the folios and can now be considered to be part of the object’s history.

Repairs were carried out to stabilise the damaged areas of paper and ensure that no further damage would occur through handling. As the thin Islamic paper was particularly susceptible to distortion with the addition of moisture, the repair methods were chosen carefully to ensure that only a very small amount of moisture was introduced. The tears were repaired using remoistenable tissue, a very thin Japanese tengujo paper pre-prepared with 1% methyl cellulose adhesive. Along the spine edge the loose fibres were secured with thick wheat starch paste. In some areas bridge repairs were added to support small parts of the paper that were at risk of detaching.

For the bridge repairs, Japanese paper fibres were teased out from the torn edge of a long-fibred kozo paper and rolled together between finger and thumb to create tiny bridges. The repair fibres were then pasted with wheat starch paste and positioned carefully across the damaged areas.

Whilst working on these charming miniatures I had the chance to observe some of the techniques used by the artist(s). Scoring lines (visible in raking light) had been used to plan out the symmetrical designs and under-drawing was visible where the pigments had been lost from the faces and turbans. Interestingly, the pigment on the back of the black horses had a shiny finish and there was slight cupping of the painted surface. This suggests that a surface coating was applied locally over the black pigment before burnishing to create this lustrous finish. The undersides of the black horses were left without this additional surface treatment leaving the pigment more matte, possibly to give the effect of shading.

After treatment, the Mamluk folios were secured in window mounts using T-hinges made from Japanese sekishu paper adhered with wheat starch paste. The folios will be on display alongside other treasures from the Chester Beatty collection, in the exhibition ‘Gift of a Lifetime’ (19th October 2018—28th April 2019). We do hope you’ll come and see it!

Celebrating the 50th anniversary of Sir Alfred Chester Beatty’s magnificent bequest, Gift of a Lifetime (19 October 2018 – 28 April 2019) presents a choice selection of masterpieces from this unique collection. You can find out more about some of the treasures in the exhibition here

 

 

No need for Magic: A simple trick for the display of a Batak manuscript

Amongst the treasures at the Chester Beatty is a small collection of 51 Batak manuscripts – 45 bark books, 4 inscribed bamboos, 1 bone amulet and one paper manuscript. Hailing from North Sumatra in Indonesia, the oldest of these manuscripts is dated to the 19th century. The Batak manuscript culture encompasses written texts on various organic materials including bamboo, bone and tree bark. The bark books, also known as pustaha are divination books, although other subjects such as medicine and magic are also common.

Presentation2

Right: CBL Sum 1144, a small size bark concertina manuscript held closed with a band of plaited rattan; Left: CBL Sum 1147, an inscribed bamboo rod

In preparation for a rotation of the Batak display case in the Sacred Traditions gallery, I condition checked four bark manuscripts. They were all in good condition and required very little attention, with the exception of one object (CBL Sum 1102).

The bark concertina manuscripts vary in size from some which are small enough to fit in the palm of your hand, to others which are around A4 in size. They are made of two wooden covers glued to a folded textblock made from the bark of the alim tree or agarwood. The stiff bark is prepared in rice water to allow it to soften and be folded into a concertina book.

In the typical East Asian fashion, lacquer was used to seal off the raw edges of the bark at head and tail of the concertina textblock. This provided extra strength to the most vulnerable part of the exposed textblock.

Inside the textblock, the text runs vertically in plain black ink, following the folds in the concertina. There are additions of elaborate illustrations and tables within the text, sometimes highlighted in red ink.

Sum 1129

CBL Sum 1129 open textblock

The wooden covers of the Batak manuscripts are sometimes decorated with hand-carving, and always carefully cut to the size of the manuscript or left slightly larger to provide a square which would protect the textblock. To hold the concertina books and their wooden covers together when closed, a band of plaited rattan or sometimes leather is used.

On many examples, handle straps are attached to the upper cover of the larger books. They are made of a dark coarse material, probably tree fibres of the sugar-palm, and roped together to create a handle. This enabled the owner of the manuscript to transport them from site to site and also to store the book on the wall, away from rodents and moisture.

On manuscript CBL Sum 1102, the sugar-palm fibre straps on the manuscript upper board were bent down and had lost their 3-dimensional aspect. As the curator wanted the object to be displayed closed, with the straps held up to give some context to the object and meaning to the straps, we needed to find a solution to support the misshapen straps, as invisibly as possible.

Sum 1102

CBL Sum 1102 with sugar-palm straps bent down

The use of a Perspex or brass rod support underneath the strap was considered and a few unsuccessful ideas were tried out such as Melinex supports, manipulation of the straps and humidification, I decided to go back to basics.

Using a simple thread which was attached to the strap on one side and to the display case fabric on the other, I hoped that the strap would stay in place. Luckily for us, the bend in the strap was facing away from the back of the case. This meant that with a very simple low-tech thread the same colour as the fabric lining the case, I could pull the strap in to place using enough tension to pull it up for the duration of the display. In a worst case scenario, the thread would give way well before any damage to the palm fibres occurred and would only lead to the handle coming back in to its bent position.

Presentation4

I used an extremely fine 100% orange silk thread which I looped around the book cover handle and into the fabric at the very top of the case and knotting it to itself. The system is extremely discreet and after a few months of display, the thread has held and I am happy to say that the handle is still standing!

Working on the display of the Batak manuscripts was extremely rewarding. Problem solving is what conservators love best and I was happy to be able to use a simple, low-tech solution for the display of this manuscript. It is sometimes all you need.

Miniature Masterpiece: Repair Work Revealed

Earlier this year 144 fifteenth-century medieval miniatures from one of the Chester Beatty’s most treasured works, The Coëtivy Hours (CBL W 082), were re-mounted by the conservation team in preparation for the temporary exhibition, Miniature Masterpiece: The Coëtivy Hours (9th March – 2nd September 2018).

In general, the miniatures were in good condition and did not require any treatment prior to re-mounting, but one particular miniature, CBL W 082 f.295, required rather more care and attention.

An unsympathetic historic repair along the spine edge of the folio had caused the parchment to deteriorate and it was decided that conservation treatment would be beneficial, in order to improve the physical and chemical stability of the folio before it was mounted. For more information on the mounting process do take a look at our previous blog post here.

Fig 1

Fig 2

CBL W 082 f.295 in transmitted light.

Four distinct areas of damage were visible along the spine edge of folio 295. It is likely that the losses may have occurred when the folio was removed from its binding, and could possibly correspond with the sewing stations of this previous structure.  Unfortunately, when the damaged areas were repaired, the infill paper that was used was thicker, more yellow and several shades lighter than the original parchment, immediately detracting from the delicate illumination. When viewing the folio in transmitted light, it could be seen that the repair paper overlapped the parchment on both the recto and verso by 1-5mm. This overlap was not only visually displeasing, but also increased the risk of tensions occurring if the folio were to expand and contract in response to changes in relative humidity. In addition, the parchment along the repair edge had darkened and become embrittled, possibly due to aging of the adhesive with which the repair was applied.

For these reasons, it was decided that the historic repair and any residual adhesive should be removed, in order to prevent any further deterioration of the parchment support. Since parchment is very sensitive to moisture, mechanical removal of the repair was attempted in the first instance, but this was not successful. Instead, a small damp brush was used to introduce just enough moisture to swell the adhesive so that the repairs and adhesive could be carefully removed with a small dental tool.

Fig 3

Fig 4

CBL W 082 f.259 after the historic repairs had been removed.

As often occurs during conservation treatments, there was a stage where the object looked a lot worse than before the treatment began! As well as revealing the true extent of loss to the spine edge, removing the old repair revealed two small tears in the parchment. These were repaired on the verso of the folio using RK2 remoistenable tissue, prepared using isinglass (a proteinaceous adhesive derived from the swim bladder of sturgeon fish). Isinglass was chosen for its excellent ageing properties as well as its strong adhesion at low concentrations. It is also a collagen-based material, just like parchment. The prepared remoistenable tissue was cut to the desired shape and peeled off its Melinex backing. Then the repair paper was carefully positioned over the tear, activated with a damp brush and left to dry under a small weight. When dry, the two tear repairs were trimmed down and the folio was ready to be infilled.

Fig 5

Details showing the torn areas on CBL W 082 f.295 before (left) and after (right) repairing with remoistenable tissue.

The paper chosen for the infills was a Japanese sekishu paper (20 gsm), dyed with yasha (click here for more information on how this was prepared). The paper was thinner and lighter than the parchment, to ensure that it would work in harmony with the folio and avoid incurring any tensions between the two materials.

The folio was placed over a light box and a layer of Melinex was used as a barrier between the folio and the repair paper above. This allowed the shape of the first damaged area to be traced onto the repair paper with a water pen. A bamboo spatula was used to score along the same line and to tease away the remaining paper, revealing a feathered edge. Next, the edge of each infill was trimmed down with scissors and pasted with wheat starch paste. Over the light box, each infill was carefully positioned (with a 1mm overlap between the repair and the folio) and left to dry under light pressure. After treatment, the folio was mounted in the same way as the other miniatures and is currently on display in the Miniature Masterpiece: The Coëtivy Hours exhibition.

As an intern, this small project was a fantastic opportunity to learn more about parchment conservation. Discussing treatment options with the conservation team here at the Chester Beatty Library was an invaluable experience and I look forward to applying what I have learnt to new parchment projects in the future.

Seductive Marvels of Japanese Art– Materials and Techniques of Surimono Prints  

Surimono prints were the focus of the exhibition “The Art of Friendship: Japanese Surimono Prints” on display at the Chester Beatty Library in the spring-summer 2017. This exhibition of 95 single prints and poetry books from the collection gave us a chance to study in detail the making, techniques and materials of Japanese woodblock prints, especially focusing on the more elaborate Surimono.

The_Art_Of_Friendship_ 08

“The Art of Friendship: Japanese Surimono Prints,” an exhibition at the Chester Beatty Library.

The most lavish of Japanese prints, the quality and refinement of Surimono appealed greatly to Sir Alfred Chester Beatty. He acquired the greater part of his Surimono collection- a collection that is considered one of finest in the world- between 1954 and 1963, having already moved his Library to Dublin.

The word Surimono means simply ‘printed thing’. Prepared as gifts for exchange among friends and acquaintances at New Year and on other special occasions, these privately-published prints were products of the flourishing literary culture of Edo Japan. The Surimono commissioned by poetry circles in the late eighteenth and nineteenth centuries combine short verses composed at poetry gatherings with designs prepared by leading artists. Taking their subjects from the scholar’s desk and the literary canons of Japan and China, Surimono embody the eloquence and amity of these cultivated salons and offer a glittering glimpse into a world rich in playful allusion.

Because of its small audience and private funding, Surimono artists and printers could produce exquisitely refined prints with delicacy and great care. They were usually limited to between 50 and 150 copies.

The basic printing technique used to create Surimono prints was similar to the commercial Ukiyo-e prints although the Surimono prints appear to be much more intricate in design. They exhibit finer and much more elaborate details, more colours, more patterns, more blocks and therefore no expense was spared.

Seductive Marvels of Japanese Art

Details of Surimono prints showing the intricacy of the design.

Japanese woodblock printing is a technique which involves the use of many different blocks of wood to produce one multi-colour print. The wood commonly used for the block is a hard cherry wood which was prepared and planed to achieve a smooth surface. The age of the block and the preparation had a direct impact on the finish achieved in the prints.

The design is first drawn on paper and then pasted face down with a starch paste onto a wooden block so that the design is reversed, ready to be carved and printed the right way up.  The block carver then cuts the design into the block by preserving the raised motif which will be printed.

Slide3

The initial drawing is adhered to the wood block (left); the wood carver cutting into the wood to created the raised motif (right).

The key block (Omohan) was produced first. It was printed in black and at this point annotated by the artist to describe which colours should be used where. With this decided, the other blocks for the different colours were carved.

Kento is the registration system traditionally used by Japanese printmakers.  It includes two parts, the hikitsuke kento (line stop) and kagi kento (key). Multi-colour woodblock prints require a separate block for each colour, and the kento marks insure the blocks are aligned with precision to print the colours on the paper.

KentoBEST
The Kento Registration System.

To prepare for printing, the pigments were mixed with water and sometimes animal glue (nikawa) in ceramic bowls. The block was moistened first and the pigment was applied with a brush onto the surface of the woodblock. There are different type of brushes available depending on the size of the area to be coloured and the desired effects. For example, tonal gradation could be achieved at this stage by using dampened cloth or water brushes to apply the pigment to the block.

The printing paper was dampened before being positioned onto the block using the kento marks. Next the back of the sheet was rubbed over the coloured block using the baren, a circular printing pad. The process of applying the colourants onto the block and rubbing them into the paper with the baren was repeated until the desired colour saturation was obtained.

Slide4

The paper used for Surimono prints is a kozo paper with strong fibres that tends to be heavier and more absorbent than the paper used for commercial prints. It is believed to be unsized, although a small amount of sizing might have been used to avoid smudging of the colourants in the areas that are printed.

The full sheet of o-bosho paper or “presentation paper” is 39 x 53.5 cm but was not commonly used as a whole. Rather the sheet would have been cut into different sized pieces, following established patterns to obtain different formats. The most common format is Shikishi-ban, an almost square sheet about 21 x 19 cm, which became the standard for Surimono printing and was rarely used for Ukiyo-e prints.

Picture8

CBL J 2107 Shikishi-ban format.

There are two important differences to note between commercial Ukiyo-e and Surimono which are central to understanding Surimono. The first one is to emphasize Surimono prints as luxury objects with extensive use of precious materials. These include the heavy, unsized paper and the use of mica powder and metal pigments. The prints were also more labour intensive to produce, using more elaborate techniques. Surimono printers used the highest quality and the finest materials available as well as showing off their finest printing skills.

The second major difference is that the poem which accompanied each image was carved into a separate block than the key block, by a wood carver specialising in cutting script. This block would usually display the finest lines and imitate calligraphy perfectly.

Picture13

Detail of CBL J 2107 showing a variety of effects used to reproduce different fabrics.

The use of metal pigment is common on Surimono prints. However, real gold and silver are rarely found. Instead brass, copper and tin are quite frequently used, sometimes as a background, but quite often to highlight small areas of the design. The metal powder was mixed with large amounts of animal glue (nikawa) and printed on the paper last to avoid transfers of the large metal particles onto the paper during the printing process.

 

 

 

Picture11

CBL J 2078, Fluidity of the line of text.

Mica (kira) is composed of phyllosilicate minerals. The white luminescent appearance was used to highlight prints. A mixture of glue, usually a gum, and the mica powder was applied to the block and then printed gently with the baren. It was sometimes applied above a coloured ground or mixed with the pigment before printing. Another method is to cut a stencil, place it over the print, and brush the glue directly onto the paper and lightly apply the mica powder onto it and brush any excess off once dry.

Picture12

CBL J 2313, Use of mica powder to highlight the body of the watch.

Maybe the most striking difference between ukiyo-e prints and Surimono is the extensive use of embossing-a technique which is not commonly used in ukiyo-e. There are a number of ways in which this was achieved.

Blind printing (Karazuri) is a form of printing without the use of any pigment. The technique involves carving a pattern into a woodblock and then printing it in the usual way, but without any pigment. The pressure of the baren on the back of the paper causes part of the paper to be squeezed between the wood and the baren, and flattened. This type of embossing is the most common and the one often used for highlights.

In areas of Surimono where the embossing appears to be coloured, it means that the pigment has been applied before the embossing, multiplying the amount of work necessary.

Slide1

CBL J 2284, Blind embossing and coloured embossing.

Convex embossing (Kimedashi) was produced by removing a concave area in the block and pressing the piece of paper over it. The paper is pushed down into the carved spaces of the block and moulded into a new shape. This type of embossing was often used for larger areas where the mark of the embossing is visible at the verso and the paper does not remain flat.

The exhibition and the catalogue were a real dive into a marvelous world of beauty and luxury. Because privately commissioned, cost was no object and this shows in the wealth of techniques and materials that the artist, wood carvers and printers used to produce the Surimono prints. Leading artists such as Hokusai and other prestigious Ukiyo-e artists dedicated large portions of their work producing these refined Surimono prints.

Summer at the Chester Beatty

Over the summer, the Conservation team were delighted to offer a student placement (18th July- 11th August 2017) to Jana Müller. Jana is currently a student in the Conservation of Works of Art on Paper, Archives and Library Materials at the State Academy of Art and Design in Stuttgart, Germany. We’re happy to share this post from her.

On the first morning as I walked through the busy streets of Dublin on my way to the Chester Beatty Library, I arrived to find the conservation laboratory as an oasis of calm and concentration, only occasionally interrupted by screaming seagulls. Throughout this placement the seagulls have reminded me that I am right beside the sea.

My first project was the remounting of Surimono prints. The Chester Beatty Library has around 400 of these special Japanese woodblock prints and I had the opportunity to work on 31 of these lovely artworks. For various reasons discussed in a previous blog post here, the whole collection of Surimono prints is currently being remounted. The first step in this process is to lift the tabs from the old board with a little moisture and a spatula so that they can be reused later. Secondly, each object gets two more tabs attached at the bottom edge using wheat starch paste in order to keep it in place in the float mount later. Each unique Surimono is measured for a window mount and, once it is cut, the object is positioned and the tabs at the top of the print are attached to the new mount.

Slide5

Two moveable window mounts simplify the measurement of the new mount (left); The 2mm overlap of the tabs attached at the bottom edge of each Surimono allows for quick removal if necessary (centre); Once the tabs are attached to the new mount, they are allowed to dry under weight (right).

The remounting worked really well and it is interesting to see how the impression of an artwork can be changed with a new mounting system. I also got to have a close look at the fine printed lines and I gained a better understanding of how these prints are produced. There is so much work in every single print, which further increased my admiration for the beautiful Surimono.

Another project was the in-situ conservation of an Italian parchment manuscript from 1472 (CBL W 113). Due to a very tight library binding some quires of the textblock were loose and had stepped forward. The threads at the centrefolds of these quires had ruptured. Three strong creases parallel to the spine edge had caused further damage. Usually one would humidify the parchment to bring it back to its original shape but in this case the different colourful inks in black, blue, red, green, yellow and purple seemed to be highly sensitive to moisture. To avoid the risk of bleeding, the creases were flattened under dry conditions using only weight and time.

The creases could be reduced within a couple of days so that the text is readable again without restriction. I had never tried this method before and I was surprised by how well the treatment worked. Another necessary treatment was the local consolidation of flaking pigment layers on two of the fully illuminated folios. With a very fine brush I applied a special natural adhesive made from sturgeon swim bladder—isinglass—beside the flaky pigment, and capillary action drew the adhesive between the pigment layer and the parchment securing it to the folio again.

Slide2

The next project I worked on was an Ethiopian manuscript (CBL W 913). The codex is written in Ge’ez, the Ethiopian language, and is dated to the late 17th or early 18th century. The illustrated parchment folios show scenes from the life of Christ and are in an excellent condition. However, the damage to the codex affects the connection between the heavy wooden front board and the textblock. The board attachment was completely broken at the two inner sewing stations and severely damaged at the outer ones. For this reason, there was a high risk that the front board would detach from the textblock, particularly as it needs to be handled for digitisation. To prevent further damage, the two inner sewing stations were supported gently by introducing new threads, led through the original channels in the wooden board and attached to the original thread at the board edge. The two outer sewing stations were supported with twisted Japanese tissue, also led through the board, and then fanned out and pasted to the spine edge of the first quire to distribute the stress away from the delicate original thread.

Clockwise from top left: Ethiopian manuscript CBL W 913, detail of the broken threads between the wooden boards and textblock; using a curved needle to lead the twisted Japanese paper through the board; after treatment, the new threads stabilise the connection between the board and textblock.

The result is a very honest conservation treatment: the new material is clearly visible because of the brighter colour but it is unobtrusive at the same time. I am a little bit proud of my suggestion to use twisted Japanese tissue because it is very tear-resistant, flexible and versatile. I will definitely keep that technique in mind when working on projects in the future.

Beside my conservation treatments I had the opportunity to help with a number of rotations in the permanent exhibition galleries, which needed to be done quickly before visitors walk in at 10 am! Overall, I had the opportunity to see many beautiful objects from the diverse Chester Beatty collections. You can gain an idea of these stunning and detailed objects here.

For conservators, it is very important to work as much as possible on objects to improve and practice the various treatments we learn, and to make sure every method is well-known and reflected upon. At university, it is difficult to spend enough time on objects between classes and exams, that’s why internships are so important. I had a great time at the Chester Beatty Library. My lovely colleagues made me feel very welcome and I was able to improve my skills while learning new things on objects from different times and countries. I gained more self-confidence as a conservator and I am now looking forward to starting my master thesis next year.

The Art of Friendship: Japanese Surimono Prints

The Chester Beatty Library’s collection of surimono and picture calendars extends to some 375 single sheet prints. Alongside these are the kyōka books and a further 116 surimono with illustrations in the Shijō style popular in Osaka and Kyoto, many of which are preserved in albums. The greater part of this collection was formed between 1954 and 1963.

Acquired by Sir Alfred Chester Beatty for his newly built Library in Dublin, the collection took shape under the specialist guidance of Jack Hillier and Beatty’s own developing interests in Japan’s printed arts. As works created through the collaboration of artists and poets in celebration of new beginnings, it is fitting that these prints were collected in that same spirit.

2017 marks the 60th anniversary of diplomatic relations between Japan and Ireland: an event precipitated in March 1957 by an exchange of letters between the Japanese and Irish ambassadors in London. The Chester Beatty Library is marking this anniversary with a special exhibition The Art of Friendship: Japanese Surimono Prints (March 3 – August 27 2017). Dr Mary Redfern, curator of East Asian collections, selected 95 single surimono prints for exhibition and a number of poetry anthologies and surimono albums all from the Library’s own collections and many by leading artists such as Hokusai and Gakutei. This new exhibition focuses on the surimono and the literati circles that created them.

The Library received a generous grant from the American Friends of the Arts in Ireland (AFAI) which enabled the Chester Beatty Library to conserve, mount and frame all the prints and related material currently on display.

The overall condition of the surimono collection is very good. The prints were all carefully mounted when the Library received funding for a conservator to travel to Dublin from Tokyo to advise and oversee the project. The mount card used nearly 40 years ago was conservation quality but quite thin and lightweight, so offered little support during handling and would not have prevented the prints touching the glass when framed for exhibition. The window apertures had been cut without a bevel, and overlapped the edges of the prints, hiding precious details of the images from scholars and visitors. The decision was therefore made to remove them from their historic mounts, and transfer them to new standard size mounts made from heavier (1650 micron) acid-free, buffered Conservation Board.

The prints had been attached to the previous mounts with conservation standard handmade Japanese paper tabs, so these were gently lifted from the backboards and retained where possible. Each print was then gently surface cleaned using soft brushes.

The prints were then carefully measured and in order to fully reveal the detail of the surimono, the new bevelled-edge apertures were cut slightly larger than each object so that the entire print could be seen. In order to mount the prints in this way, additional Japanese paper tabs were attached to the bottom edge of each print with wheat starch paste. These additional tabs along the bottom edge allow the prints to ‘float’ in the aperture, whilst the tabs hold them safely in place under the bevelled window.

The surimono were then carefully positioned in their new mounts, and the uppermost Japanese paper tabs were secured to the backboard, again using wheat starch paste and dried under weights.

New mahogany-coloured frames were ordered and each print selected for exhibition was framed by the team. Bespoke archival boxes have been ordered to house the collection while in long-term storage.

The seven bound volumes to be included in the exhibition were all in good condition. They were surface cleaned and minor tear repairs carried out where necessary. Bespoke acrylic cradles were made to exactly fit the opening of each volume. These were then installed in three display cases in the Library’s Temporary exhibition Gallery.

Finally, the framed prints were hung in the gallery ready for the opening on 3rd March.HangingThanks to the generous grant provided by the American Friends of the Arts in Ireland, the Chester Beatty Library has been able to ensure the long-term preservation of this rare and beautiful collection.

The Art of Friendship: Japanese Surimono Prints runs from March 3 until August 27, 2017. We hope you’ll have the chance to visit the exhibition over the holidays.

We don’t mind Mondays!

As regular visitors to the Library will know, the museum is not open to the public on Mondays during the winter months (November – February). However you may be surprised to hear that Closed Mondays are often the busiest days of the year, especially for the conservation team.

There is a small but dedicated staff at the Library and we all work onsite so are used to the general background noise and buzz of our wonderful visitors (over 370,000 people last year). So on that first Monday in November the museum always seems eerily quiet, but not for long.

Cleaning larger collection objects around the Library.

An essential part of disaster prevention is the Library’s very busy annual maintenance programme which ranges from clearing gutters and checking roof tiles to servicing the lifts and running fire drills. Phased improvements and repairs to the fabric and decoration of the building are planned to coincide with closed Mondays, so that they have minimum impact on our visitors.

For conservation it offers an opportunity to carry out essential maintenance in the galleries. Display cases are opened and the interior glass cleaned, artsorb used to maintain a stable relative humidity levels is changed and our environmental monitoring system is annually calibrated. The collection includes some beautiful Chinese vases and furniture which are on open display, so these are carefully cleaned using soft brushes and microfiber cloths.

Changing the scroll displays in the Arts of the Book gallery.

We have two permanent galleries-Arts of the Book and Sacred Traditions– the key themes within these exhibitions remain the same however the collections on display change annually. The curatorial staff work with the conservation team to carry out phased rotations across the collections.

From March, the Library re-opens seven days a week and today we are open to the public. However our work doesn’t stop there as we will now start planning our next maintenance programme over a very welcome cup of coffee from the Silk Road Café.

In with the new: gallery rotations

In preparation for our current temporary exhibition Hong Ling: A retrospective, curator of the East Asian collection, Dr Mary Redfern, selected a number of objects from the Chinese collection to complement the exhibition. The items are displayed in the Arts of the Book gallery, and have been installed as part of the annual rotation of the galleries in order to coincide with the new exhibition opening.

The conservation team is involved in all aspects of preparation for gallery rotations. We condition assess each individual item before undertaking conservation work as necessary. Stabilisation of fragile objects includes pigment examination and consolidation if necessary, paper repairs, and sometimes also work on the covers or binding structure of bound volumes which might otherwise be too fragile for display.

Once each artefact has been stabilised, we can then begin to plan for its display in the galleries. The mounting system for bound codices involves carefully measuring and drawing the open profile for each manuscript, before commissioning a tailor-made Perspex cradle that supports the unique opening of each book.

Mounting a print with temporary Melinex V hinges; Installing a scroll in a bespoke Perspex mount in the gallery.

We mount prints individually in conservation standard window mounts. If the mount will be a temporary home for the print or folio, we often use Melinex V hinges to attach the print to the mount board. This method is very useful as it does not require any adhesive to be in contact with the object. Once the mounting system is secure, the mounts are installed in the display cases using Perspex pins at top and bottom to hold them in place. Scrolls are carefully unrolled and both ends fitted into C shape Perspex holders which are secured to a sloped support. Using internal blocks and panel measurements, together with Perspex fittings, we try to ensure our mounting systems disappear and do not distract from the beautiful objects.

When we are finally ready to install the objects, we work closely with the curator to decide their placement in each case as well as lighting. We keep light levels at a maximum of 50 lux to protect the delicate and light-sensitive pigments and inks. Once the objects are installed, we monitor the environmental conditions in the galleries each day to check they remain stable and that no fluctuations in temperature or relative humidity are recorded.

The objects removed from display to allow these new items to go on view are then condition checked in the conservation lab before being returned to storage for a well-deserved rest. Blocks, frames and mounting systems are safely put away, ready to be used again in the near future.

Installing an ink study gifted to the Library by the artist, Hong Ling.

Hong Ling: A retrospective is open now and will run until January 29th 2017. We hope you’ll have the chance to visit the exhibition over the holidays. Make sure you also take a look at the Chinese section in Arts of the Book to see the treasures on display including Hong Ling’s beautiful ink study which the artist gifted to the Library to commemorate the opening of the exhibition.

 

Thank you for following the Chester Beatty Conservation blog during 2016. We’d like to wish you all a happy and peaceful festive season, and we look forward to sharing more of our work with you in the New Year!

Goya on the Go: Lending The Disasters of War

A selection of forty prints from the Chester Beatty collection have just gone on display in Belfast as part of an in-focus exhibition, Francisco Goya: The Disasters of War, at the Ulster Museum.

In September I started work on the preparation of this iconic series of prints. The Chester Beatty holds a complete Second Edition of The Disasters of War (Los Desastres de la Guerra) by Francisco de Goya (1746-1828). Formed of eighty aquatint prints, the series was first produced around 1820 and later printed in Madrid in 1892.

The prints were originally kept as a bound album. However, at some point in the past century the prints were removed from this format and mounted individually in window mounts for display. As the mounts were slightly too small for the prints, they had come in contact with the gummed linen tape used to assemble the mounts and in a number of cases the prints had adhered to the mount board, probably as a result of excess moisture applied during mounting. Apart from this, the paper support and media were in good condition, with only slight planar distortion in the printing plate area.

Elisabeth Randell, a student in Paper Conservation at Camberwell College of Arts in London, started the conservation treatment of these objects during her summer placement with us. First, Elisabeth removed the prints from their unsuitable mounts, before gently surface cleaning them using chemical sponge and erasers as necessary. Old hinges were then removed using locally applied moisture. Edge tears were repaired as necessary using Japanese tissue and wheat starch paste.

I continued the preparation of the prints by adhering new Japanese paper hinges to the upper edge of the folios using wheat starch paste. New conservation-standard window mounts were then prepared, and the prints were carefully secured in the mounts using Japanese paper T-hinges. This allows the prints to be turned so that the verso can be viewed without incurring any damage.

During my work on the prints, I was also assisted by Adam Macklin, a student in Book and Paper Conservation at the University of Amsterdam, who volunteered at the Chester Beatty Library for one week. Adam’s help was invaluable at each step of the mounting process, and ensured the work was completed on time.

Finally, I assisted with the packing of the objects for travel. This included the preparation of six conservation-grade phase-boxes, the proper wrapping of the objects, and finally packing the crate for safe transport. The 40 prints to be exhibited were then transferred to the Ulster Museum, where they were framed by Conservator Gillian O’Neill and her team. Once framed, Julia Poirier and I travelled to Belfast to oversee the installation of the prints in the Ulster Museum’s print gallery.

Thanks to this amazing project, I now have a much better understanding of the complete loan process in an institution. Working with different stakeholders was highly enriching, and taking part in the installation of the exhibition in at the Ulster Museum in Belfast was a great reward.
