	Crucibles
	For over 131 years assayers have relied on DFC crucibles. DFC crucibles are designed to give dependable service at normal temperatures (1800°F to 2400°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. more >>
	Canon Industrial Ceramics has a wide range of Dental, Jewler and specialized Melting and Casting Crucibles more>>
