Conservation for Digitisation: Arakanese Buddhist Manuscripts from the Murray Collection by Ana C. García Pérez
I'm excited to share the uniqueness of two fascinating items I worked on during my time with the Conservation for Digitisation Team as part of my internship, and to discuss a specific conservation treatment that proved to be both effective and insightful.
The items in question are part of the Murray Collection at the British Library and are currently being digitised as part of the Murray Digitisation Project. These items are believed to be among the few surviving examples of Buddhist literature written in Arakanese from the eighteenth century (see Fig. 1, 2, 3, and 4).
Each item consists of loose pages made from two pieces of paper glued together with an adhesive that, in some cases, had ceased to be effective, causing some of the leaves to delaminate at the edges (see Fig. 5).
The aim of the project was to prepare these items for digitisation. Therefore, my focus was on reattaching the layers of the partially separated pages to prevent further damage or complete separation during handling by non-conservation-trained staff throughout the digitisation process. To achieve this with minimal intervention, I used V-hinges made of tissue to reattach the partially separated pages from the inside at the edges, rather than gluing the two layers of paper directly back together.
Here’s a detailed look at the four-step process I followed:
1. Surface Cleaning:
- Prior to the adhesion of any V-hinges, a surface cleaning process using smoke sponges was carried out on the areas where adhesive was to be applied, in order to avoid possible tide lines.
2. Cutting and Preparing the V-Hinges:
- After preparing remoistenable Tengujo Japanese tissue a 1:1 solution of Methylcellulose (MC) and Wheat Starch Paste (WSP), these were cut into several 1 cm² squares (see Fig. 6)
3. Attaching the First Side of the V-Hinges:
- For the initial attachment of the squares onto one of the two paper leaves comprising each page, I focused on working with only one half of each tissue square, ensuring the other side extended beyond the edge of the paper to be adhered later onto the partnering paper of each page. To do this, each square was placed onto a Melinex piece with the adhesive side facing up, where only half of its adhesive surface was reactivated.
To achieve this, moisture could have been applied to the desired area to re-activate the MC and WSP solution due to its water-based nature. However, in this instance, I opted to apply an additional layer of the solution to further enhance its adhesive strength (see Fig. 7).
- Since the treatment aimed to create V-hinges to reconnect the two leaves of paper comprising each page, only one half of each square was reactivated and adhered to the inside edges of the lower paper, leaving the other half of the square extending beyond the leaf (see Fig. 8).
- The number of squares adhered varied based on the extent of delamination on each page, ensuring sufficient adhesion to keep the two leaves together.
- A piece of Bondina, a blotter, and a light weight were placed on the area where a hinge was adhered to enhance the drying process and prevent possible paper deformation (see Fig. 9).
4. Attaching the Second Side of the V-Hinges:
- Once the first half of the V-hinges had dried, a strip of Melinex was inserted between the leaves of paper and placed onto the adhered half of a square, folding the “untouched” half of the tissue square over itself and the Melinex strip towards the inside of the page (see Fig. 10). Then, the other half of the square tissues was adhered to the upper leaf of paper following the same method as for the first half.
Figure 10 - Add. 1253-F. The second half of a tissue square is folded over itself and a Melinex strip, ready to be adhered to the upper leaf by reactivating the adhesive on this side of the tissue
By inserting a Melinex strip between both halves of a V-hinge during the adhesion of the second side, I prevented the two papers from sticking together as the adhesive dried, ensuring the adhesive on the upper side did not interfere with the one already attached to the lower paper (see Fig. 11).
- Again, a piece of Bondina, a blotter, and a light weight were placed on the area where a hinge was adhered to improve the drying process and avoid possible paper deformation.
5. Finalizing the Attachment:
- After the adhesive dried, the Melinex strip was easily removed, as nothing adheres to it, and the process was repeated for each V-hinge (see Fig. 12).
Although this technique is commonly used in conservation mounting, it was exciting to apply it as conservation-stabilisation work. I appreciated how this technique respected the current condition of the items and the effects of time on them, while also serving to structurally stabilise the partially delaminated pages, preventing further damage during the digitisation process, and preserving their original appearance. Similarly, this technique allows access to the inner area between leaves of paper if a researcher needs to investigate the original adhesive used. In such cases, a conservator could easily slit the V-hinges at the fold and reopen the leaves of paper that were held together by the tissue hinges.
