White lead ore, also known as cerussite, is a mineral commonly found in lead deposits. It has a white or grayish color and is composed of lead, carbon, and oxygen. Often used as a paint pigment, white lead ore has several synonyms, including lead carbonate, lead sulfate, and plumbous carbonate. Other names for this mineral include lead spar, white ore of lead, and white lead ore. While white lead ore was commonly used in the past, its toxicity has since caused it to be banned from use in many countries. Alternative paints and pigments have since been developed to replace traditional lead-based products for safer and healthier options.
