Description

Crucibles. DFC products have an unexcelled, time-tested reputation and are known for being manufactured with high quality, raw materials to exacting specifications. Covers are optionally available for all crucibles. Melting crucibles are made from the highest quality raw materials for the best mechanical strength in melting and refining gold, silver and other non-ferrous metals.

Standard Clay. Designed to give optimum service under standard conditions. These units have been used for assaying, refining, smelting, fusing and testing for many decades. Dependable service at normal assaying temperature (1800-2000°F)

Premium Clay. A relatively recent development, on demand, giving improved resistance to wall erosion and higher refractory qualities (2250°F). when this unit is used, additional silicon and/or borax may be needed to obtain fluid fusions.

Fused Silica. Has excellent resistance to thermal shock for use in melting and refining up to 2750°F.

Corderite. Used for non-ferrous metals where pouring temperatures do not exceed 3000°F.

Colorado. Multi-purpose use. Crucible designed to endure many melts. For glass melting or analyzing difficult ore bodies. Composite of alumina, silica, fireclay. Max. 2400°F.

Special. GENEQ will respond to inquiries for special size crucibles of other compositions such as: silicon carbide/carbon, clay graphite/ceramic and carbon. Thin wall and bilge type shapes are also available.
