Lifting and missing gold foil - 金の薄板の剥離と欠失

This image, taken prior to conservation, shows, to the right, wrinkling and lifting of gold foil caused by movement of the substrate induced by fluctuations in RH. To the left, an area of gold foil has been lost completely. Tarnishing of the silver foil in the centre of the image can also be seen.

修理前のこの写真の右側は、相対湿度の変動による木地のくるいを原因とする、金の薄板の皺と剥離を示すものです。左側では金の薄板が完全に欠失しています。さらに中央の銀の薄板の変色も認められます。
