I have been casting with deox silver which I get from AAA refinery
Portland, Or. and really enjoy working with it. Don’t know ifit is
the same formula as that sold by Rio. The dexox I get casts
beautifully, no porosity, and malleable enough so that when I make a
ring which needs enlarging to fit a client’s hand, I just put it on
the mandrel and hammer away. Best of all, it never tarnishes.
I have been casting with my centrifuge. Have not tried it with my
vacuum, so don’t know if the results will be the same. Alma
