A Silk Binding in Need of Repairs

by Erin Hammeke, Senior Conservator

Kigen nisen-roppyakunen… is a Japanese book of photography with a lovely silk binding that’s falling apart. The cover is detached and the fragile silk covering is shattering on the spine. Silk is challenging to repair, especially on a bookbinding where components need to flex and be manipulated.

Split image of the front cover of a book. On the left side the book is being photographed in visible spectrum of light, showing a blue silk cover. On the right side of the image, the book is photographed under UV light, showing fluorescing ink and adhesive residue I’ve had to experiment with different adhesives to readhere the lifted silk over repair material in a way that doesn’t cause staining to the original covering – which is difficult! I’m experimenting in small areas on the binding and tracking the effectiveness of various methods by using UV imaging (above, right) to see whether there is also any staining that isn’t visible under full spectrum lighting (above, left).
