So I'm on a hunt for the Perfect Project Material...and I'm not having a lot of success. What I want is pretty specific. It's a sculpting compound that cures into something resilient but spongy...sort of like foam or rubber. I've tried Crayola's Model Magic, but the result was just too crumbly.
So...er...the first trinket I tried to make out of silver PMC didn't exactly work out as planned. Therefore I've turned the dry clay particles into slip. But can you use pmc slip to cast something using a mold? I sort of tried it earlier, but there were a lot of bubbles that formed. Anyone have any advice for making this go smoothly?
I've been getting into a holiday mood lately, and this is the result. He's supposed to be the Spirit of Christmas Present. >_> I always did like the more antiquated Christmas feeling. You know, lots of baroque frills and lots of gold, red, and green.
Hmm. Looks like it might be the same as craft porcelain, but it's hard to say for sure. You could always roll out a ball as a test piece, let it harden, then dunk it in a cup of water for a while to see what happens.
I know Sculpey makes a kind of polymer clay specifically for mold making. It works best to chill it in the fridge for a few minutes before pressing your figure into it. Otherwise...I don't know if it would hold up to melted wax or not. I mean, it doesn't take a lot of heat to melt wax anyway...could experiment and see, I guess!
Ditto about the release. If you have problems with that, try experimenting with different release agents- i.e. coating the mold interior with soft soap, talc powder, and other substances.
Wow, those are fantastic! I used to work at a miniatures museum and those are really on the level of some of the things we had there. Great job at nailing realism! Can't believe you even got the wood grain right!
Hmm. Are you thinking about using stuff like craft porcelain? If so, it does tend to rehydrate when it comes into contact with water. Honestly, I think most moisture based clays would. However, you might be able to use it and then seal it with something. Add several coats of acrylic on top, or pond sealant or something...that might work.
