Sorry- it's a little misleading. The original was made of clay. Then the plaster mold is made around it. Then the mold is broken open and the clay is scooped out and the mold is washed out, and then it's seamed back together again, and then something else more permanent is cast inside it. The clay is only used for modelling and then discarded. This head is cast in densite.
Heh, I thought the same thing. Densite *isn't* much different from plaster, which is kind of irritating in a way, as it's pretty easy to scratch and break it when the mold's being chiseled off. On the plus side, it's going to be pretty easy to repair or carve out places where the mold kinda broke apart. It seems more fragile than I'd hoped, unfortunately. I hope it can withstand the playa, as I'd like to bring it out there.
'cause the mold is just made of plaster and is being chipped into millions of pieces as I get it away from the head. But if we got molding stuff and made another mold of it, then we could do that. But it'd take kind of a lot. It's a life-size head.
haha! it's totally right in the picture that the mold is being broken away. i'm retarded.
you know, if you had made that mold with a combination of smooth-on's brush-on silicones and their mother-mold plastics you could cast 100's of big heads before the mold would even _begin_ to deteriorate!
*product number here* has a pot life of about 4 minutes, and you can't expose it to moisture, so a good bet might be a silicon *product number with some letters here*, as that's a good all purpose one- but you need a special spray, you know, something like *product number here* would work well. And it'd have a durometer of 30 and a viscosity of eight million viscoparticles. That's about right, right? NIBBETS! Not the non-slarking narkocompfs- we'd defintiely need the slarking ones for that, and the *product number* mold release agent. We'd definitely need that, too, right?

hey now that you have that mold why don't we cast some rubber or plastic in it, dig out the inside and put a speaker inside with a tape player?
no - a walkie-talkie with a speaker in the mouth and then at burningman we could stand far away with binoculars and give shit to people who walk by!
