Chapter 12. The ways of the lustre: Looking for the Tunisian connection

Abstract

Recent excavations at the Fatimid and Zirid site of Sabra al-Mansuriya near Kairouan (Tunisia) provide the first evidence of lustreware production in medieval Ifriqiya, in the 10 th-11 th centuries AD. As the Fatimid dynasty moved from Ifriqiya to Egypt to establish its capital in Fustat (Cairo), technological connections with the Egyptian lustreware could be expected. Tunisian lustreware may also be the link in the transmission of the technique towards Muslim Spain. It represents a new piece of the puzzle of understanding the diffusion of lustre technology from the East to the West of the Mediterranean. The composition and microstructure of the bodies and glazes, and the micro-and nano-structure of the lustre layer are compared in a preliminary approach to the technological relationships between Tunisian, Egyptian, and Spanish lustrewares. Petrographic (thin section) and SEM-EDS analyses of bodies and glazes were performed at the archaeometry laboratory of the DIP.TE.RIS (University of Genoa, Italy). Chemical microanalyses of glazes were carried out on at least
