Lead glaze, a type of ceramic glaze which is commonly used for pottery, is a term that is often used interchangeably with other similar expressions. Some of the more common synonyms for lead glaze include fritted lead glaze, lead crystal glaze, red lead glaze, and galena glaze. These other terms can be used to refer to specific types of lead glaze, or to describe variations in the amount of lead that is present in the glaze mixture. However, it is important to note that lead-based glazes have been found to be harmful when ingested, and can pose health risks, particularly to children and pregnant women. As such, many contemporary artists and manufacturers have moved toward using lead-free glazes.
