I was quite pleased to receive the new Journal of the Institute of Conservation, Vol. 33, No. 1, 2010, since Alexis Hagadorn and I have an article included in it titled “The use of parchment to reinforce split wooden bookboards, with preliminary observations into the effects of RH cycling on these repairs”
Here is the abstract:
“Split wooden boards are a common problem in early book bindings, and treatment can be complicated by the need to disturb original components as little as possible. A technique used to reinforce or rejoin fully or partially split wooden boards using parchment has been evaluated. A reinforcing parchment strip has sometimes been employed to treat cracks in wooden musical instruments and examples of reinforcing strip repairs to wooden bookboards have also been observed. The books considered in this article presented an opportunity to use this technique and make observations about its merits. With favourable results but some questions, the authors undertook a systematic study of this method, considering and comparing several options for re-joining split wooden boards. Samples of some common repair techniques were made and subjected to relative humidity cycling to compare how each method might withstand extreme RH fluctuations at a constant temperature. The response of reinforcing strip repairs to RH changes showed a negative impact on join adhesion within the sample group, which may indicate that modifications are necessary to improve this technique. When re-examined after three years, the treated boards were intact and stable.”
It took over four years from the start of the project until the revised manuscript was accepted for publication, but it is gratifying to see the results of our research, and images of a couple of my treatments in a peer reviewed journal. Unfortunately, the journal is not available online yet, although I have heard it is in the works. And if you are not a member of ICON, this single issue costs, gulp, $228.oo!
