Hi, I am trying to get info on Pewter. I have tried Corning
rubber, Kerr vel-mix with little success. The Rubber is good for
small items, and the vel-mix has been of little success. This
gypsum, or is it all gypsum products don’t seem to be able to
keep the edges when used for a split mould. Each mould I created
chipped at the edge, creating flashing when used a second time.
This is the problem. Not to sound cheap but I would like to get
more than one pour from a ceramic mould. I was wondering if I
could use a bronze master as a core and a ceramic exterior,
would it stop or lessen the other problem, that of the metal
freezing partway down the mould. Naturally I get to the end to
tell you what I am trying to create. I am trying to use Pewter
for wine goblets and attaching a fancy wooden base. I have
probably left out and lot of info, so could you or someone email
me with questions and or directions.
Thank you for your time
