PbS
Description
Galena, chemically identified as lead(II) sulfide (PbS), functions as the primary geological source for lead extraction and serves as a significant secondary reservoir for silver. Within the ceramics industry, it has historically been recognized for its role in lead-based metallurgy and mineral processing. Its distinct mineralogical composition provides the essential chemical foundation for lead compounds used in traditional glaze formulations, where it acts as a potent flux that lowers the melting point of silica and enhances the development of lustrous, smooth glass surfaces in pottery.
