Hi misswendiki,  Grin

I'm new to this site, however I'm not new to polymer clay. Polyform Products Co. The makers of Sculpey have a product called Sculpey Super Flex Bake and Bend. It stays stays rubbery and flexible after baking. I have made very detailed of molds out of it that I have had for over a year and they are still flexible. The molds should withstand the temperature of your soap because this product bakes 285. The only problems I can think of would be chemical reactions with your soap or if you use a mold release. You can contact the company and I'm sure they will help you with any questions that you have.

Here is the link from Sculpey, I hope it helps. Good luck.

P.S. I know that for a while the 2 oz. blocks were unavailable, I don't know what the status is now.

Both MoldMaker and Bake and Bend may have less than totally-smooth finishes though, so you might have a tiny bit of texture or just less clarity in your soap after using them.  I haven't tried regular polymer clay for pouring soap so don't know what would happen in terms of any releases needed, or whether cooling to remove would be sufficient, etc.... regular polymer clay molds can't have any undercuts though.

If you really want a very smooth and flexible material to make a mold from for soap, a 2-part silicone molding material should work great. It won't be cheap for the size you probably, but the expense may well be worthwhile for just a mold or two (... plus you can always use the concept of a "mother mold" behind the flexible one so that you could make the mold itself thinner and not use up as much molding material).

There's lots of info on silicone molding materials,brand names,  where to buy, how to use, etc. on this page at my site:
http://www.glassattic.com/polymer/molds.htm
(it also has info about all kinds of other molds including polymer clay ones --made or purchased --and on various releases)
(... click especially on 2-Pt Silicone Putties and Releases..)


Good luck!
