Also, what does a crucible do?

Crucible are used in the laboratory tocontainchemical compounds when heated to extremely hightemperatures.Crucibles are available in several sizes andtypically comewith a correspondingly-sized lid.

How does an induction furnace work?

An induction furnace consists of anonconductivecrucible holding the charge of metal to be melted,surrounded by acoil of copper wire. A powerful alternating currentflows throughthe wire. The magnetic field induces eddy currents,circularelectric currents, inside the metal, byelectromagneticinduction.
