Pis forPewter
Pewter is a metal alloy made from around 85% tin, and the remainder being antimony, about 1% copper and 4 or more percent lead. It is commonly used for photo frames, vases and decorative mugs. Plates, bowls and cups were all made from pewter before glass and porcelain became more common.
People of ancient cultures used to get lead poisoning partly from eating from pewter plates, and partly from using a lead compound to sweeten their wine.
