A pot in which metal is held, while melting in a furnace is called as a “Crucible.” It is made of silicon carbide and clay graphite. Of course there are many different types of crucibles and the type of material you are using. Crucibles are also differentiaed by their shape and the materials used to create the Crucible.
A bilge shaped crucible has the shape of a barrel. The part of the crucible in the middle region is called as a bilge. An “A” shaped crucible has a narrow bottom and a wider top. There are straight sides that are bent outwards. The diameter continuously increases from the base to the top. Both the mentioned shapes can be manufactured in Clay graphite and silicon carbide.
