I needed a prop for a laser security mine for a fan film (similar to the mines in AVPR), and was knocking around with a lump of clay just to see what proportions etc looked good, and here's what I came up with:
The more I look at it the more I like it--it doesn't have the straight edges that the AVPR model did, but I like the "organic" look that gives it. So I think I'll go ahead and paint it up.
But because it's just made of clay, it's very delicate and I don't want to break it, so I'd like to somehow make a cast of it. And alas the only experience I have with anything like casting was when I was a kid and used to make casts of animal footprints by building up a little paper dam around them and filling it in with melted candle wax.
So I'm looking for a cheap disposable method (preferably from commonly-available stuff--I don't want to go ordering professional-level stuff yet until I have half an idea what I'm doing with it) of making a couple casts of this. What I've brainstormed so far is using Home Depot silicone to make a mold and then using liquid latex to fill the mold, or maybe using plaster of paris to make a mold and filling that with Home Depot silicone.
Would any of those have any chance of working reasonably well, or am I just wandering totally off into the woods here?
I don't really need a sturdy permanent mold because I'm only going to make one or two casts of it.
Any help is appreciated--I'm utterly a rank amateur at this.
