Royal Selangor produces high quality cast pewter, which is heavier and stronger than spun pewter. Each Royal Selangor item is hand cast by pouring molten pewter into steel moulds quickly and efficiently. After cooling, each individual piece is polished and soldered onto other appendages such as spouts and handles, all done by hand. This attention to detail and precision has made Royal Selangor's pewter pieces durable and timeless. Pewter is an alloy composed primarily of tin. The world's fourth most precious metal after platinum, gold and silver, it becomes pewter with the addition of small amounts of antimony and copper.
