Anybody actually make graphite-sulphur plastic? (construction, I guess)

Anybody actually make graphite-sulphur plastic? I stumbled on it at: http://www.makestuff.com/sulphpl.html while looking for ways to make closed molds for fiberglass fabrication.

It seems like it would be a great way to make misc items for the house and shop, and after you're done with it you could just melt it down again for something else.

If somebody else has played around with the stuff I've got a couple of questions: First, does it stick well to polymers? After reading the description it looks like it would be a great backing for the mold tooling gelcoat or epoxy - but only if it would stick to it.

Second, how stable and strong is it? I'd hate to actually make the stuff and use it only to have it degenerate back to regular sulphur after a while.

The reason Im asking is that the two ingredients are really cheap compared to castable resins and I'd have the added benefit of being able to recycle it right there at the shop.

I guess if nobody knows I'll have to order the ingredients and find out for myself..... fun project though... making your own plastic

Thanks

Dave

dave sounds a little bit like the sulfer molds old timers used to make chamber impressions on guns.from what I read read it had this weird way of expanding about an hour after the mold was made,then shrank again a few hours after that.I'm not sure how recastable it would be.
