Abstract

Historical decorated glass and glazed ceramics are studied with the object to determine the technology of production and to relate it with the optical properties (colour, shine, opacity). Four different case of study are investigated: production technology and replication of lead antimonate yellow glass from New Kingdom Egypt and the Roman Empire, technology of production of polychrome lustre, analyses of Syrian lustre pottery (12th–14th centuries AD) and study of color and dichroism of silver stained glasses. These different coloured glazes or glasses have in common to be produced by the presence of micro or nanoparticles embedded into the glaze which give their special optical effect. Chemical and microstructural analyses are performed using a selection of complementary Microscopic and Spectroscopic techniques that are the most adequate for the analyses of each decoration. Physical optical properties are also modeled and measured by means of UV-Vis spectroscopy. The composition and structure of the different phases formed during the processing of the decorations in historical times is obtained with the object to learn about their stability and processing conditions and to relate them to their optical properties
