Features of the reconstruction of the lost elements in the museum practice on silver items

Abstract

The purpose of the article is to develop a methodological basis and solve the problem of the peculiarities of the addition of lost elements in works of precious metal in the restoration process. In practice, it has been established that the insulation of additions with materials that are widely used in modern museum restoration is not able to create a completely inert layer and insulate the anode-cathode system between the added parts and the original. As a result of corrosion caused by atmospheric influences, the metal is destroyed, galvanic corrosion is accelerated, the additions are eventually destroyed due to oxidation, and the original loses its historical appearance. The article organizes information on the study of epoxy resins, the use of which in the restoration of silver objects is not universal due to their complicated reversibility. The methodology is based on scientific and experimental methods, analytical – to reveal the essence of each of the functions, generalization – to clarify the international requirements for modern scientific restoration of metal works. The scientific novelty of the research is to develop a restoration technique and create a tool for the restoration of works of decorative and applied art from silver of non-archaeological origin in museum restoration. Conclusions. Restoration measures, such as the addition of losses on works of decorative and applied art made of silver in museum practice, need careful research and optimization. The use of lead and tungsten as a filler has a number of advantages in the chemical-physical, ethical and aesthetic fields of modern scientific museum restoration. The article has significant theoretical and practical significance, as it explores the features of the addition of losses, the possibility of using the tool as a material for casting the lost element, mastication of cracks and minor gaps. The study of the peculiarities of the addition of silver objects can have a successful practical implementation in museum restoration.
