will Apoxie Clay and Magic Sculpt stand up to the Vulcanizing Process?

[jami 415]

Curious question, Will other epoxy based clays like Magic Sculpt and Apoxie Clay stand up to the vulcanizing process?

What about pieces in cast Urethane resin? Ive been told that aluminum filled epoxy will, but what about just regular Urethane resin from Smooth-on.com?

Reason i ask, is because back in college i remember in jewelry class i made a vulcanized mold of a pendant in sculpey, but it was for jewelry, the teacher assisted me, so im curious if anyone knew if the vulcanized molds for jewelry were similar to vulcanized molds for spin casting.

I think that green stuff is perfect for small things 20mm and under, but for larger 40mm-90mm it seems like magic sculpt works better because its more workable, and easier to add to.

I was wondering if anyone has considered this/done this before.

MagicSculp certainly can (lots of masters that are cast in metal have been sculpted in MS) but I don't know for sure about Apoxie Clay.

I think if you check Apoxie's literature they give the cured hardness ratings for their various products, and if Apoxie Clay's is around the same as MS or AS then you should be okay.

Check with Smooth-on? I think it could stand up fine, but it would depend a bit on the shape and size of the piece and whether it's free-standing or projects outwards.

Generally I'd agree.

Short answer? I've yet to see anything withstand the grip. I reckon Kirk might have gotten away with it by pretending to be dead, but I can't tell for sure.

Epoxie clays tend to stand up to the pressure just fine. Where you get into trouble is with magic sculpt, it's more brittle so fine details that are hanging out by themselves (fingers and such) can break off. I use Magic Sculpt all the time for stuff that's going to be vulcanised but I will switch to magic sculpt for the finer parts.

Apoxie Sculpt?

um, wait a minute, you mean you sculpt in Magic Sculpt then switch to Apoxie sculpt for finer parts, or you start out with apoxie clay for the body, but then switch to Magic sculpt for the fingers because its harder?

Im confused...?

But youre saying it will withstand atleast the first pattern mold, but smaller parts will break in the process..?

Note to self - make sure brain is engaged before replying

I use Magic Sculpt for big bulkier parts and a more flexible clay for finer bits. Lately I've been using Green Stuff for the finer bits. I've also used a clay called Pro Create which, like GS, cure's somewhat flexible.
