I cast with gold scrap and have been using an additive called "
Majic Cast " to do away with oxidation problems. The
manufacturer recomends using 5% added to the metal, but I only
use 3% and get very clean results. I’m very happy with the
results, but not the cost. A bottle costs about $35. for majic
cast, and $18 or so for another company’s product. I would think
this stuff is mainly zinc. Could someone give me a little help
with making my own additive for casting scrap gold. I can’t
help but to believe there is a much cheaper way to go about this.
I somehow feel foolish spending the money when there has to be
an equivalent that costs pennies. Thanks for your help!
