Casting from Paper Mache molds?

[oreloki]

First livejounal post ever, so bear with me if this winds up in the completely wrong spot. Recently, I recovered a nice, small pair of antlers from a buck that was sadly made roadkill near my house. It was kinda gross, but I digress. I was wondering if it would be at all possible to make a mold of them using paper mache. I've seen people cast resin

Paper mache is not water tight and not a very good mold material. You can't use porous materials (like clay, paper, etc) as a mold for resin.

Have you heard about oogoo? You make it from silicone caulk and corn starch. A little more expensive than paper mache, but not nearly as expensive as real silicone molding material.

No, this is definitely the first time I've heard of it. I might have to give it a try, though! It looks like it will work just the way I need it to.
