Pewter Casting. Pewter casting is a Medieval art form. Designs often consisted of animals. Pewter is an alloy of tin and a little copper. Pewter has a low melting temperature of 500-750 degrees. Pattern Allowances. PATTERN. In casting, a pattern is a replica of the object to be cast, used to prepare the cavity into which molten material will be poured during the casting process. PATTERN.
