A glass table saw is used to cut your glass into various shapes and works very similar to one you might use for wood. Pictured is a Taurus II.2 Ring Saw manufactured by the Gemini Saw Company. I purchased mine from Ed Hoys. However, they are available through most vendors that sell glass fusing and stained glass supplies. These wonderful saws allow you to cut out intricate designs that are, if not impossible, at least very difficult to cut by hand.
