Pewter used for food vessels must be lead free and contain 92% tin, 6.7% antimony, and 1.2 % copper as required by both U.S. Government regulations and the APG (American Pewter Guild).
The ancient Romans used lead to make plumbing pipes, as joining pins for limestone building blocks and it was popular amongst Roman alchemists. Historically, tin and lead were hard to distinguish between. The Romans called lead 'plumbum nigrum' (black lead) and tin was called 'plumbum candidum' (bright lead). The melting point of lead is 621.4 Â°F (327.46 Â°C) and the boiling point is 3,180.2 Â°F (1,749 Â°C). In 2008, Australia, China and the United States produced the most lead.
