Casting
It is used to produce items of various shapes, in order to complete the dovetailing of a sculpture, but also enables the casting of sculpted items made of a single piece.
By using a readily available furnace, an amateur metallurgist can easily achieved the required temperature to melt tin (232°C), lead (328°C), zinc (420°C), aluminum (660°C) and copper (1085°C). The mixing of some of these metals in well-defined proportions will yield bronze (copper/tin) or brass (copper/zinc).
This furnace can be powered by gas, charcoal or electricity. Once melted, the metal is poured into either a sand mold or a mold manufactured using the “lost wax” casting method.
