| Abstract: | Conclusions. The results of the investigation proved that the leather of the gospel-book binding was chrome-tanned. Its colour coating contains two layers. The binding media of the first one are nitrocellulose. The upper layer contains linseed oil. The colour substance of both layers is methylene blue. The original coating was preserved in the areas under the silver applications and in the bands of the leather under the fly-leaves. In the other parts of the leather it was rubbed out to a large degree. In accordance with the original technology of its manufacturing and with recipes from the period of the object's dating, we assume two blue finishes for the colour unification of the leather. The recipes are as follows (numbers in weight units, e.g. g). 1. First finish with nitrocellulose as the binding media: nitrocellulose Summaries. An analysis was made of the leather cover of a gospel-book that had been submerged in a river for some days. The findings showed chrome-tanning, double coating with nitrocellulose and with linseed oil, and a dye of methylene blue. This accords with historical information on the making of gospel-books in Bulgaria and with the development of leather technology in this country in the period 1925-1945. On the basis of the experiment results and of formulas for leather coatings from that period, recipes are given that may be useful in the conservation finishing of leather binding. |
