A jeweler uses a crucible and blowtorches as a metal melting forge. Types of foundry melting furnaces. Traditionally, cupola and crucible furnaces were the most common ways to forge metals for casting; in the modern day, electric arc and induction furnaces are common. Crucible furnaces. Crucible furnaces are the most basic form of metal furnace.

The ladle must not be allowed to dip into the furnace when the valve is not actuated. A circuit diagram with a back-pressure valve must be developed to cater for the case in which the ladle is very heavy. The requirements of the exercise are met by the first circuit diagram only if the ladle represents a light load.
