Methods of obtaining sheet brass and production of thin-walled brass products in the XVIII - early XX century

The article examines the influence of methods of manufacturing blanks from sheet brass on the properties of the final products and their safety during long-term storage. An overview of the main directions of the use of sheet brass in historical development is given on the examples of technical devices and household items, works of art and crafts. The changes in technology that occurred in the considered and previous periods are shown, the reasons for such changes are given. Numerous disparate publications describing the technological processes of manufacturing blanks and objects from thin-sheet copper-zinc alloys - brass - in the XIII-XX centuries are used, the information from which in the article is arranged in a consistent presentation of production processes. The article allows you to form a complete picture of the basic methods of converting the initial workpiece into the final product and the types of alloys used. Close attention is paid to a detailed description of metal processing techniques, tools and equipment used, in order to assess the impact of production and technological factors on the metal structure at the end of the manufacturing process. The recommended bibliography helps to navigate the difference in the properties of the metal of the monument when choosing a scheme of restoration intervention. The author of the article comes to the conclusion that it is possible, based on external signs and the results of the analysis of the metal structure of the monument, to identify objects that need preventive and restoration work to prevent their destruction, which is possible even in museum storage conditions.
