Metals recovered in fire assaying crucible are the metals that emerge from the fusion of the material in a assay furnace, for gold, usually at temperatures of about 2,000 Degrees F. The Fire Assay Method is centuries old, but it is still one of the most reliable methods for performing assays (to determine the metal content of a ore) of ores that contain precious (noble) metals - Gold, Silver and Platinum.
Accuracy in sampling, preparation, assaying, handling, weighing is extremely important in fire assaying,
since errors will influence the 0.0001 g final gold bead in sometimes astronomical proportions, if done improperly, using un-scientific methods, and little attention paid to the assay process.
It is important to choose a high quality fire assay clay crucible
Customised size is acceptable.Top quality and quick service are our goal.
Fire Assay Crucibles have a higher than normal resistency to cracking under fire assay conditions. Our crucibles are used in laboratories throughout international marketplace. We have a variety of shapes and sizes available to cater to specifications required.
Our crucibles give longer life, faster melting, constant melting speed and exceptional resistance to violent changes of temperature.
