Using the correct RTV is a good suggestion, but I have to admit I am
just starting to carve, mold and cast, so I just assumed the flexible
wax wouldn’t work. I will try it since I now have the equipment to
make the molds and cast.
One person suggested pouring injection wax on plates to make sheets,
controlling the thickness, which seems like it may work very well
for me. I am assuming that when standard injection wax cools it would
have the rigidity I am looking for, even at 20-24 ga.
One pro caster recently told me you need 20 ga. thickness in a wax
backing plate to get good casings, which is certainly heavier than
the sheet I fabricate with.
My fabricated pendant designs have a pretty thick bezel, two 12 ga.
square wires stacked, soldered and shaped, then soldered to 24 ga.
I am hoping to cast these settings in one step, with a resulting
back plate that has the properties of real sheet. Otherwise I will
probably have to cast the bezel and solder sheet to it.
I would appreciate any input on this, and thanks very much for the
tips! What an invaluable resource this is.
