Welcome to us.cupellation problems :
has anyone had this problem before? i guess platinum family is messin with me.
i have a prill from smelting ore with flux's at about 1250 . i belive i half assed scorification with only 2 to 1 lead and cupelled at about 860Welcome to us.
Platinum metals pose no problem in cupels.
What do you have in the cupel?
Describe in detail please.
removing the value, its brittle and theres a rose color powder and gold flakes. some cupells come out with red arms. amazon test stuff says 22k or better, also platinum. so im not getting solid metal.i have a prill from smelting ore with flux's at about 1250 . i belive i half assed scorification with only 2 to 1 lead and cupelled at about 860
There should be no flux in a cupel.i have a prill from smelting ore with flux's at about 1250 . i belive i half assed scorification with only 2 to 1 lead and cupelled at about 860
Did you use Lead or Bismuth as collector metal?There should be no flux in a cupel.
It beats the purpose of the cupel.
Cupelling needs the correct temperature and plenty of air to drive the oxide into the cupel.
Are you talking C or F here.i have a prill from smelting ore with flux's at about 1250 . i belive i half assed scorification with only 2 to 1 lead and cupelled at about 860
That looks like a alumina crucible to me, not a cupel. What is it exactly?cupellation problems :
