Pewter has been used for ornamental and utilitarian purposes for over 3000 years. It is a tin alloy which is durable, relatively easily worked, resistant to corrosion and can be similar to dull silver in appearance. These qualities can result in pewter objects lasting hundreds of year, often in good condition.
