After you have a fused product, you can slump it in a mold so that it takes on the shape of that mold. In fact, you don't even need to have a fused product to do this; you can slump one piece of glass if you want. It will be thin and not very interesting.

So the way you slump is to put the fused glass product on a mold. Remember it must fit the mold fairly well; so you must pick the mold from the very beginning and work your way towards now. The glass should be slightly bigger than the mold, so that when it slumps, it comes out to be about the size of the mold. After you put the glass on a mold, you put the whole thing in a kiln, and heat it at 1300-1400 degrees F for as long as it takes for slumping to occur, usually within a couple of hours.

Here's one sample piece I made that takes on the shape of an ashtray by slumping:



Here's another piece which takes on the shape of a funny looking vase by slumping:
