The invention of lustre: Iraq 9th and 10th centuries AD

In this paper the study of four significant lustre samples covering 9th century AD polychrome and 10th century AD monochrome lustre from Iraq is presented. The samples selected are representative of the earliest known lustre productions. The data obtained from the study of the medieval samples are compared to laboratory reproductions and gives important clues about the invention, perfection and success of lustre during this period. The change from polychrome to monochrome lustre decorations and the increase in the lead content of the glazes are the key parameters in the success of obtaining a golden lustre.
