Glass for Fusing, Stained Glass & Lampwork

Start with one question: what are you making, and at what heat? Stained glass panels use sheet glass cut cold, then joined with copper foil or lead came - no kiln needed, so any cathedral, opalescent, or textured sheet works. Fusing and slumping are different: every piece in a single firing must share one coefficient of expansion (COE), or it cracks as it cools. System 96 and Bullseye 90 are the common fusible families; mixing them ruins a load. Lampworkers and beadmakers reach for COE 104 soft-glass rods and stringers worked over a torch. Buy frit by grit, from powder to coarse, for color blending, and dichroic for metallic flashes. Sheet glass sells by the square (roughly 6x6 to 12x12 inches) or by the pound for scrap and mosaic. Expect $4-$12 for a small fusible square, $8-$20 per stained-glass sheet, $15-$40 for rod bundles or frit jars, and $20-$60 for dichroic. Many makers ship in 3-7 business days; cut-to-order and large sheets run 1-2 weeks and need padded packing.

Filter by COE (90, 96, 104), form (sheet, rod, frit, dichroic), and color, then check related searches to match your fusing or stained-glass technique.
