For over 131 years assayers have relied on DFC crucibles. DFC crucibles are designed to give dependable service at normal temperatures (1800°F to 2200°F).
DFC melting crucibles are especially designed for melting gold, silver and other non-ferrous metals. These crucibles are widely used for refining and for melting other materials having melting points up to 2750°F.

The complexity of some of the samples being analyzed has resulted in DFC Ceramics developing crucibles to match the arduous conditions required.
