The production of a lead glaze with galena: Thermal transformations in the PbS-SiO2 system

Galena, also known as PbS, was widely used in the production of lead glazes from the beginning of the 18th century to the second half of the 20th century. Although the PbO-SiO2 system has been studied for years, the PbS-SiO2 phase diagram, involved in the formation of a glaze with galena, has not ye...
