Key conservation issues: degraded old fills and poor quality retouching - 保存修復上の主要課題:経年劣化した充填剤と質の劣る後世修理跡

The Mazarin Chest has numerous losses to its vulnerable lower moulding. This image shows how the poorly executed gesso (a mixture of animal glue and powdered chalk) fills used to remedy this were neither level nor smooth, and were painted in black and gold in poor imitation of the original decoration. Retouching extended over the edges of the fills, obscuring parts of the original surface, and the whole moulding was varnished in an attempt to make the repairs less noticeable. It can also be seen how the areas of repair were themselves damaged over time.

マザラン・チェストは損傷を受けやすい下辺の枠部分に多くの欠損が見られます。この写真はこの欠損部を埋めるためにジェッソ剤(アニマルグルーと石膏粉の混合)が施されている様子を示します。ジェッソは均等に施されておらず、元の装飾に模して稚拙に塗った黒と金の塗料が見られます。修理部分を目立たなくするために、元の塗膜と充填部の境目を覆って塗料が施され、枠部全体にワニスがかけられています。これらの修理部分にも損傷が見られます。
