Ifriqiya (roughly Tunisia and eastern Algeria) is believed to have played a significant role in the diffusion of ceramic glazed technologies into other regions of the Western Mediterranean. However, due to limited analysis on North African glazed ceramics, its role in technology transfer remains poorly understood. This paper uses SEM–EDS and petrographic analyses to understand the technology employed in the production of Tunisian ceramics through the study of 30 polychrome glazed ceramics from a medieval settlement at the site of Chimtou (ancient Simitthus), Tunisia, dated to the late ninth-twelfth century. The results show that these are lead-rich glazes with varying contents of alkalis, coloured with copper, iron and manganese oxide and applied over a calcareous body. Opaque glazes were obtained using cassiterite crystals as opacifier or by adding crushed quartz. The use of lead stannate as a colourant and opacifier in one light yellow glaze raises questions about the mechanisms of introduction of tin opacification technology in North Africa. Scrap metal seems to have been used as a source of lead for the glazes; while iron slag was probably used as a source of iron to colour the glaze in one sample, pointing to a cross-craft interaction between glazemaking and metallurgy.

据信，伊夫里奇亚（大约是突尼斯和阿尔及利亚东部）在陶瓷釉面技术传播到西地中海其他地区方面发挥了重要作用。然而，由于对北非釉面陶瓷的分析有限，其在技术转让中的作用仍然知之甚少。本文使用 SEM-EDS 和岩相分析，通过研究来自突尼斯 Chimtou（古 Simitthus）遗址的中世纪定居点的 30 件彩色釉面陶瓷，了解突尼斯陶瓷生产中采用的技术，这些陶瓷的历史可以追溯到九世纪末。十二世纪。结果表明，这些釉料富含铅，具有不同的碱含量，用铜、铁和锰的氧化物着色，并涂在钙质物体上。使用锡石晶体作为遮光剂或通过添加碎石英获得不透明釉。在一种浅黄色釉料中使用锡酸铅作为着色剂和遮光剂，引发了人们对北非引进锡遮光技术机制的疑问。废金属似乎被用作釉料的铅来源；而铁渣可能被用作铁的来源，在一个样品中为釉料着色，这表明制釉和冶金之间存在跨工艺相互作用。
