Modern pewter is a soft metal, an alloy made with tin that is hardened with the addition of copper and antimony. Originally, pewter was hardened with lead. After long-term exposure to lead was discovered to cause brain disorders, its use in making pewter was discontinued. Antique pewter pieces continue to be in demand as collectibles. Lead-based pewter pieces, which become very dark as they tarnish, and lead-free pewter, which tarnishes slowly, have different cleaning requirements.
