How do you apply lacquer to non hardening clay?

I was just makin some random sculptures when I made some thing alot of ppl thought was nice, so i need to harden it.

Best Answer - Chosen by Asker: successful mold making takes experience. If you don't know what you are doing you are more likely to destroy your piece than make a copy.
If you made it once, you can make it again, and what's more, your second try will come out even better.
So I'd recommend to regard this as practice or as making a model of something you want to make.
Now you make it again, you'll make it even better, and you'll use oven bake (polymer) clay to do it. Then you can paint that with acrylics or whatever color you want.
