Product Tags
Cupellation is the last and crucial stage in fire assay process.so,the quality of cupel is very Important .
During cupellation,the lead is oxidized to litharge(PbO),most of which is absorted by the cupel.Gold,silver,platinum and other precious metals form a tiny bead in the cupel.
The cupels are removed from the furnace, allowed to cool and the gold bead is weighted.Finally,we can calculate the content of precious metals.
Jintuo advantage of cupels as followings:
1. Manufactured with unique blend of Magnesium Oxide and special fluxing ingredients.
2. Regular testing at our own assay lab .
3. Rapid absorption of large quantity of litharge.
4. Free from cracking and pitting.
5. Beads are easily removable.
6. Perfect uniformity of quality.
7. Consistently low losses.
8. High refractoriness(1100 centigrade degrees),rapid absorption(70%),and recovery rate of 97%-98.5%.
Available sizes are: 6A, 7A, 7AS, 7AL, 8A and 9.
Any sizes and styles can be Customized ,pls contact with us !
