Hi,
Here is an unusual question. I would like to refinish an old heave (20lb) brass urn. As I'm working on it, I would like to take before and after (and in-process) pictures. What would be the best material to build a mold that I can set this piece on so I can place the piece in a consistent place? I'm thinking plaster or compound or something like that, and I need something that's soft at first but the solidifies, but wouldn't stick to brass while wet and is stron enough to initially support a 20lb piece with a tiny total base (4 little claw feet).
Thanks!
Aaron
