Was: Casting diamonds with inclusions in place
Hi this is in reference to the disappearing diamonds fired in Metal
I have been trying to find a warning that we had as Metal Clay
artists, but to no avail tonight. Used in the metal clay item was a
bar - from an old ring - with three diamonds set in holes - after
firing the holes were empty. At one time we were advised of the fact
that diamonds would not withstand the length of heating in the Kiln.
I have seen jewelers repairing worn tips holding diamonds, and was
amazed at the temp they could take, but I don’t believe it was
prolonged as to 30 minutes.
My only experience with it - couldn’t take the chance again - the
student was very kind and didn’t sue me!!!
Maybe one of the PMC gurus can elaborate on this situation.
