Casting Plastics


#1

Hello everyone, I have taken a great liking to old fashioned
celluloid. I would really like to be able to reproduce jewelry in a
form that is similar. Does anyone know a good plastic material for
this? I would like to cast plastics and make molds, etc. Not sure
where to start. If anyone knows how to go about this, be it a how-to
book, or a company that produces the materials please let me know.
Thanks all, A. Derenthal of crybabydesigns.com

There are resins that can be cast using the same machine that is
used to cast white metal (pewter) costume jewelry. They are
thermosetting plastic, probably available from Contenti. You would
cast them into a silicone rather than rubber mold. I made models that
were used in this process back in the early 70’s.

You might also visit a serious model-making/hobby shop. The one near
me caters mostly to people who are into model trains, but they have
lots of interesting materials and the guys who work at the one close
to me are very knowledgable in using materials that are not typically
used in jewelry.

(Some of the guys at the model shop I go to are like the
record-collecting guys (and yes, it’s all guys) in the movie High
Fidelity. It’s always fun to go in there, especially when they’re not
very busy.)
