I am getting ready to do a project using a blend of Pure Silver,
Palladium, Ruthenium,Platinum, and will be using Hydrogen/Oxy from
the torch to do the melt and pour and I will use an Argon Gas to put
a blanket of inert gas over the melt to keep down the scale and
I will be soldering pieces of 22K Green Gold on the cast pieces an
will I need to go back to Butane/Oxy to do that?
Any advise or help on this subject will be greatly appreciated.
Thanking you in advance,
This is a first for me and I seek any safe advice from those of you
that have experience in this area.
