Online Workshop: Coloured Inscriptions and Analytical Techniques
Wann: Di, 19.10.2021, 14:00 Uhr bis 17:30 Uhr
Colouring paintings has been a well-known procedure since Ancient Times, aiming to enhance the appearance of an object, such as rock-based written artefacts, sculptures, ceramic pots, et cetera. In particular, writing can be perceived more clearly or be obscured, it can be emphasised or put in the background by using different colours. Colour can also be added to express feelings and highlight details of daily life, and thus coloured cultural-heritage objects can reveal peculiar characteristics of societies. The application of material-science analytical methods to colours and in particular to mineral-based pigments is vital to gain information about the structure and crystallo-chemical composition of the pigment components, which are key factors in studying the origin and the conservational history of a coloured object. Of critical importance is the use of non-destructive analytical methods, as sampling of pigments is undesirable or forbidden for most historical objects.
