Example of test results - 実験結果例

Top: 10% Paraloid B48N in toluene gave the uneven appearance typical of the six synthetic resins that were tested.

上:トルエンを溶媒とする10%パラロイドB48N。被験の六種類の合成樹脂に共通の斑が生じました。

Bottom: 15% ita nikawa gave the even penetration and moderate colour saturation typical of several of the types of nikawa that were assessed. Although none of the materials tested was perfect, the best results were achieved with a type of nikawa known as tsubu nikawa.

下:15%板膠。実験した膠数種に共通の、均等な含浸力と中程度の色の濃度を見せました。実験材料はいずれも理想とはいえませんでしたが、最良の結果を生じたのは粒膠でした。

Tests undertaken in 2005 had shown that the surface of the Mazarin Chest was water sensitive and subject to blanching if exposed to aqueous adhesives such as nikawa. Accordingly, the areas adjacent to the mother-of-pearl decoration were treated in advance with dilute lacquer (urushi-gatame treatment) to prevent damage occurring while re-adhering the shell.

2005年に行われた実験から、マザラン・チェストの漆塗膜が水に敏感で、膠のような水性の接着剤に曝されると白化を起こすことが示されていました。従って貝の剥離止め作業の際の水損を防ぐため、螺鈿部の周囲の漆部分が漆固め技法で事前処理されました。
