Casting in Sculpey for Miniatures
For Xmas, I want to make small press-out parts for miniatures, that I and a friend can paint and play with over the holidays.
I was thinking the best way would be to make the minis in re-useable pieces (head, arms, legs) and the mold out of a very firm but flexible material, and press sculpey into the mold and then stick the pieces together, cook, paint and play. I've made a few attempts with various molds pressing ordinary Sculpey into the mold and while the details are very faithfully caught the piece gets highly deformed as I tugged it out of the mold, and at the edges where it was pulling free. I was wondering if I wouldn't be better off by working the sculpey till it is warm, pressing it into the mold, then letting it cool or even chilling it, then using a much more flexible molding material (silicon, dragon skin, etc) which I would peel away from the piece. I also toyed with the idea of pressing a huge knob of Sculpey into the mold and then cutting the piece and mold away from the knob rather than trying to retrieve a piece alone from the mold. I was wondering if anyone out there had any better suggestions for how to do this? |

Casting in Sculpey for Miniatures
I use RTV silicon for my molds all the time and I bake sculpey into them.
The silicon is a two-part putty that you knead together in equal quantities. It allows 5 minutes for actually making the mold, then it starts to harden. It is quite flexible and does not stick to the clay. Hope this helps!

I haven't done this sort of thing for a long time, but I just made the mold
of sculpy, baked it, then used the mold to make more units. Easy and works fine. "LoopyWolf" wrote in message ...

I am rather new to using sculpy and seeking information. If I make molds in this manner, what do I use or do I need to use some form of mold release? My experience is more with poured ceramics where I used talc powder or corn starch as a mold release. |
