No problem. So you didn't answer my question. Do you know if you can you only use lost wax casting on brass and not pewter? Are you familiar with lost wax casting?
I'm very familiar with lost wax casting, and it can get very expensive!:eek
I've approached foundry's with pieces similar to this cross and they seem to shy away from them, due to the detail that is involved. Not that they can't do it, but they not only have to mold them and make a wax positive, but then have to clean up the wax positive and repair and fill in all the air bubbles that got trapped in the details. A lot of work is involved and I would be afraid of them messing up the details while repairing the wax positives of this cross. Especially, when there are a lot of straight lines and smooth surfaces.
Plus, when you're casting in high-temp melt metals such as brass, copper, or bronze,... as they cool, they shrink by about 10% to 15%. So, then I would have to go back and start over and make another master that is 10 to 15% bigger to get the exact size to the original.
The nice thing about pewter and other low-melt metals, is that it barely shrinks at all.

Pewter is poured into high-temp silicone molds or graphite spin-casting molds, not lost wax!
Lost Wax casting is for high-temp melt metals such as brass, bronze, copper, iron, and steel.
