White Gold casting with 12%PD

Dear all:

We are trying to produce 18k white gold castings with 12%PD. Since the
alloy isn’t available in the Thai market we are using Silver alongwith
the gold and the palladium. So far we haven’t had a single 100%
successful bowl. I should mention that we are using platinum
investment powder. Any insight is more than welcome.

Thanks in advance.

I don’t believe silver will work in this formula. I used to have
Hoover and Strong’s palladium white gold formula but it is proprietary
and I can’t give you the actual formula but I can tell you that zinc
is one of the elements used in it.
