The goal of the heritage process is to provide a comprehensible guide for identifying the most widespread art and craft techniques for the processing of precious metals, their correct description and the setting of appropriate approaches to their preventive and remedial conservation. In the first section, the art and craft techniques of goldsmithing are described in detail, based on the material characteristics of selected metals and their alloys, a description of the techniques themselves in connection with the historical context of their use, including risk factors of damage to artefacts made by these techniques. The terminology used is also supplemented, which is subsequently elaborated in the form of alphabetically ordered keyword lists in the appendices of the heritage process. The second section consists of a set of case studies containing reconstructions of the procedures of selected craft techniques, including examples of surveys of original artefacts verified in museum practice.

Methodology of electrolytic metal cleaning methods using an electrolyte based on modified gels
Rapouch, Karel ; Hájková, Kateřina ; Selucká, Alena ; Perlík, Dušan ; Kouřil, Milan
The methodology aims to provide simple instructions for conservators-restorers on how to set suitable conditions for local and gentle cleaning of corrosion products of silver and copper, in order to avoid mechanical damage to the surface of the object and influence of surrounding (especially organic) materials in the case of multi-material objects of a cultural heritage. As part of the methodology, various gels were studied in terms of their physico-chemical properties and their compatibility with chemicals from which an electrolyte can be prepared for the electrolytic cleaning of metal surfaces. Artificially patinated samples and selected real objects were used for the experiments. Furthermore, the possibility of using gel electrolytes for the study of corrosion products by the method of polarization measurements was investigated. The methodology can be applied not only in the improvement of procedures for the treatment of museum collection items, but also in the field of processing archaeological finds or in teaching conservation-restoration students and other related fields of cultural heritage care.
