Fused glass pattern bars can be made by fusing together a stack of fusing glass strips in a glass kiln or by using a pot melt to drop the glass into a pattern bar mold.
The completed bar then sliced into strips on a tile saw, trim saw or glass saw for use in other glass fusing projects.
For best results a blade designed for glass cutting should be used as normal tile saw blades will chip and may break parts of the slices.
A popular method for fusing glass pattern bars is to create a dam inside the glass fusing kiln to hold a stack of glass strips during fusing.
Dams can be square or oblong and are usually made from a refractory material strong enough to hold the weight of the glass and prevent it moving outward during the fusing process.
Ready made dam strips can be purchased or made from old cut up kiln shelves.
