If you create kiln formed glass you will eventually get ahold of a tile saw. There are all different types and price ranges. If you want precise cuts with very little chipping you’ll have to go to the top of the line models. If you go over to Clearwater Glass Studio you can learn more about tile saws. The owner of this site is Steve Immerman, whose work is so fabulous…check it out! He saws a lot of glass. And then puts it back together to make beautiful fine and functional art.
