Hi, I am from India, works as a assay chemist and new to this field. We are conducting fire assay
to check the purity of gold jewellery and artifacts, and our target is 916.6 purity. While conducting
the fire assay, the dore beads,at the time of stripping, using rolling machine, is breaking up
and getting significant variation in the result. Our inquartation ratio is 1:3 and cupellation
time is 20 minutes. Check gold purity is 999.9 and using 4 gm lead at the time of the
cupellation. It could be a great help if anybody lend me a helping hand from this
blog. Thanks in advance.
