Pewter is mostly tin mixed with tiny amounts of other metals -such as copper, lead or antimony- to maintain its malleability while making it more durable, states the Pewter Society. Each day, the London Metal Exchange is the site of industrial metals trading; the pricing process is based on the trading of metals and serves as the global reference price, states the London Metal Exchange. The metals listed on the Exchange are then priced accordingly and purchased by the pound for the production of pewter products.
Pewter is priced by the pound, which is calculated by multiplying its density -typically 0.263 lbs/ cubic inch- by its volume, state the metal experts at Oyster Pewter. The metal is typically sold in sheets based on its weight and the metals it contains. The pewter is then melted by the manufacturer and shaped into products; while the melting point is dependent on the elemental metals it contains, pewter typically begins to soften at 471 degrees Fahrenheit and becomes fully molten at around 563 degrees Fahrenheit.Learn more about Precious Metals & Gems
