Fireclay Crucible, 0.75 L, Drawing 1.T.001.001-135

The T0.75 fireclay crucible is a refractory vessel with a capacity of 0.75 L for high-temperature material processing. Drawing designation 1.T.001.001-135 identifies the product. It is used in laboratory and industrial processes, including fire assay.

Design features

The crucible holds a sample or charge inside a furnace. Its fireclay walls and base separate the contents from the furnace chamber. The compact size is suited to small samples. Chemical compatibility depends on the operating temperature and the composition of samples and fluxes.

Applications

• Fire assay of precious metals in ores and concentrates.
• Heating and melting compatible materials under prescribed procedures.
• Laboratory and industrial processing of small charges.

Product selection

Match the 0.75 L capacity and drawing designation to the process. Establish charge limits and heating/cooling procedures for each operation; melt mass cannot be inferred from crucible volume alone.
