PbCO3. Cerussite is a popular collection mineral. It is famous for its great sparkle, great density and amazing twinned crystals. Cerussite is a minor ore of lead. It has a very high luster due mostly to the lead content. Just as leaded crystal glass sparkles more brilliantly because of its lead content, so too does Cerussite.

Lead carbonate - Wikipedia

Lead carbonate is manufactured by passing carbon dioxide into a cold dilute solution of lead(II) acetate, or by shaking a suspension of a lead salt more soluble than the carbonate with ammonium carbonate at a low temperature to avoid formation of basic lead carbonate. Pb(CH 3 COO) 2 + (NH 4) 2 CO 3 → PbCO 3 + 2 NH 4 (CH 3 COO) Regulations
