Lusterware is a manifestation of metallic brilliance that appears on the surface of ceramic glaze through the formation of a thin layer containing reduced metallic particles, capable of reflecting a range of hues from golden to reddish tones. The successful formation of this layer depends on a combination of physical, chemical, and technical factors, where any disturbance in these parameters may result in diminished shine or instability of the layer. The aim of this research is to analyze the manufacturing technology and identify the factors influencing the formation of the lustre layer based on historical written sources and experimental data. Accordingly, this study seeks to answer two key questions: (1) What are the variable factors involved in the successful formation of the lustre layer? and (2) How can a lustre glaze be produced by combining insights from historical sources and laboratory methods?In terms of nature and methodology, this research is descriptive–analytical, and data have been collected through library studies, observation, and laboratory experimentation. The results indicate that three main factors—including the base glaze, the composition of the lustre mixture, and the reduction-firing process—play a decisive role in the successful development of the lustre layer

This research has been done, with the purpose of reconstructing the glaze manufacturing technology based on historical formulas with an emphasis on the carved pottery of the middle ages of the Islamic period and based on the experimental- technical method. The main questions are: 1) What was the process of development and formation of sgraffito pottery until its peak? 2)According to the available information regarding the technical operation of sgraffito pottery, how can it be revived? In this article, the history and techniques of sgraffito pottery and its developments in Iran, as well as the stages of making scratched pottery, with an emphasis on the Aqhkand type pottery, are discussed and based on this, by designing experimental-technical tests, prototyping, and testing the body of pottery and glaze has been carried out, based on observations and visual study Aqhkand pottery collection. The results showed that by considering some factors such as: coordination of the appropriate clay body, the coordination of white slip with the colored glaze, the coordination of the colored glaze with the transparent glaze coating on the body of pottery controlling the formula and amounts of the materials, the desired glaze can be restored and revived.
