Need help! clay wont come out of mold!

[Hecubus114]

I made a mold of a bust sculpted in chavant soft. It is a polyurethane mold, but the heat of being inside has turned the clay to a paste and it is stuck all over the inside. isw there anything I can use to make the clay come off??? And yes, I used generous amounts of mold release beforehand...

Make a few castings, it'll pull out any goo.

Put the mold in the freezer let it get cold. The clay will harnden the pick it out. You might save some resin.

I had thought about doing this... it wont affect the polyurethane?

 

[Fyberdyne Labs]

I am not sure. I normally use silicon or fiberglass.

It takes a little elbow grease, but you can clean it out with a tooth brush and dish soap.

Naphtha will dissolve chavant, not sure what it will do to polyurethane however. I'd test it before I tried it on any critical areas.

Freezer method works fine. Unless you have a freezer that will go to -200 or so . . .

Also, alchol works great, as does dish sop and toothbrush.

thanks guys, I thought for sure this thing was ruined... which would have been a huge downer because it was a project I've spent a LONG time working on thus far...
