The article is based on the practical and theoretical experience of both authors in the field of creative technology and ties into specific cooperation in mosaic research from the Czech environment.
In the article, the material distribution of glass mosaics and applied art techniques is put into context. The first part describes the characteristics of individual techniques and materials of glass mosaic (appearance or workability). It opens with classic split mosaic, followed by micromosaic, then the specific Czech innovations in glass mosaic techniques in the second half of the 20th century.
The second part is devoted to degradation and research methods of (especially) glass mosaics. This is a list of possible mosaic degradation processes, both indoors and outdoors. The degradation of mosaic lies in the penetration of the chemical composition of the materials used and the influence of ambient conditions (especially moisture). These factors significantly affect the degree of mosaic preservation and decide on future possibilities for repair.
The article concludes with a list of the possibilities of natural scientific research suitable for the material analysis of glass mosaics, including specific examples of glass tesserae analyses by the comparative method.
Keywords: degradation of mosaic materials, glass mosaics, glass mosaic research methods, glass mosaic materials, glass mosaic techniques
