Pewter is a metal alloy. Traditionally it was made of between 85% and 95% tin with additions of copper, antimony, bismuth, and lead. Nowadays lead is not frequently used. The McLean Museum Decorative and Applied Arts Collection contains several examples of domestic and other ware made from pewter. The pewterware collection ranges in time from the eighteenth century to the modern period and includes English and Scottish pewterware makers. There are also a number of pieces of anonymous origin.
