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.
