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.
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.
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.
