Methodology of collecting and preserving the design of Czechoslovak glass and costume jewellery 1948–1989

The methodology deals with the issue of collecting and preserving the design of Czechoslovak glass and costume jewellery from the period 1948–1989, specifically a wide range of manual and automatic commercial decorated and undecorated utilitarian glass and finished costume jewellery made of glass, metal, plastic and other materials, including prototypes. It does not include other branches of the glass industry and crafts (flat glass, packaging glass, laboratory glass, glass fibres, glass mosaics and stained glass, author's glass and author's jewellery). It provides information that will facilitate and at the same time improve the dating and description of products created in a defined period. It offers instructions for the systematization of qualified active collection, including information necessary for the appropriate care of collection items obtained in this way. The design of Czechoslovak glass and costume jewellery during the socialist period cannot be viewed in a competent manner and processed as a collection without knowledge of the essential organizational landmarks that accompanied the fields of glass and costume jewellery. These changes brought about the disappearance of old and the emergence of new brands or trademarks and are therefore important for orientation when trying to date objects, or they conditioned technological changes that are essential for describing the method of production. This information is therefore an integral part of the methodology, as well as comprehensive overview appendices
