Tungsten melts at the highest temperature of metals. But that is so much more difficult to form, and more expensive to use, rarely will it be a crucible for other metals.

Up to about 1000C they are made of clay and some are graphite. Induction melting uses graphite. Over that temperature they are porcelain.

Ceramics have a very high melting point, thousands of degrees, much higher than any metal. They are transparent to electro-magnetic induction which is used to melt them.
