Crucible furnaces :
These are the simplest of all the furnaces used in foundries. They are sparingly used in most of the small foundries where melting is not continuous and a large variety of metals is to be melted in small quantities. In these furnaces the entire melting of metal takes place inside a melting pot, called crucible, which is made of clay and graphite. The sizes of these crucibles vary from No.1 to No.400 each number representing a definite quantity of metal that can be held conveniently by the crucible.
