Casting gold into platinum


#1

I was wondering if anyone had any info or experience with
casting 14 or 18k gold directly into a semi-finished platinum
piece?


#2

Gold will flow onto platinum like solder. Try this to fill
depressions.


#3

Be sure and prepolish the Platinum piece. Now attach your wax to
it and invest and cast. When the gold meets with the Platinum it
will create a metallurgical bond and you are all set. It is a
very convenient way to make bi-metal jewelry. For more questiona

If you mean casting with platinum findings already in place, my
experience is that the gold will unlikely bond completely as the
platinum is still a little to cool to accept the new metal. It
is possible to solder and there is otherwise no harm done.
