_Casting is one of the oldest methods of re-forming metals (shaping by re-forming), melting the material to re-form it into a certain shape.
It is used today in objects like car engines, and machine parts, and jewellery.
Pewter is a soft metal which can be easily shaped and moulded, and has a low melting point of 230 degrees. Some schools have projects where students create their own pewter casts.
Common problems when casting:
Polishing becomes tricky if engraving has been made
Spitting can occur if the hot mould is placed on a cold surface causing health and safety risks.
Pewter is very soft so unwanted marking on the casting can be made
