Glass Fusing Supplies

If you're just starting, you’ll need the basics: a small kiln, fusible glass sheets, a glass cutter, kiln wash or shelf paper, and safety gear like goggles and gloves. Optional supplies like slumping molds, adhesives, and fiber paper can help you expand your creative options.

Yes. Not all glass is made to withstand the heat of fusing or bond with other glass types. You’ll need to use fusible glass with a known and tested Coefficient of Expansion (COE) to ensure compatibility during firing. Using incompatible glass can cause cracking or stress fractures.

A kiln that can reach temperatures around 1,500°F is essential. Most glass artists use electric kilns with programmable controllers for consistent firing schedules. Microwave kilns can be a budget-friendly alternative for small projects or beginners, though they’re limited in size and precision.

Kiln wash is a protective coating applied to shelves or molds to prevent hot glass from sticking. It acts as a barrier during firing and helps protect your kiln equipment. Alternatively, shelf or fiber paper can be used for convenience or specific texture effects.

Slumping molds are ceramic or metal forms that shape glass into bowls, trays, or other 3D pieces. After fusing your glass into a flat piece, place it over a mold and fire it again at a lower temperature. Be sure to apply kiln wash or mold release first to prevent sticking.

Adhesives can be helpful, especially when assembling layered or intricate designs. Kiln-safe glass glues hold pieces in place before firing and burn off cleanly in the kiln. Use them sparingly to avoid leaving residue or affecting the finished piece.

Basic safety gear includes heat-resistant gloves, safety glasses, and a dust mask when handling powdered glass or kiln wash. Always work in a well-ventilated area and use proper tools to minimize cuts or burns. Safety should be part of every fusing session, regardless of skill level.

Essential cutting tools include a glass cutter, cutting oil (optional for smoother scores), and running pliers. For more detailed work, you may also want grozing pliers, glass nippers, or a grinder to smooth edges before firing.

Fiber paper is a kiln-safe material that is a barrier between the glass and the kiln shelf. It prevents sticking and can be used creatively to add texture or relief patterns to your glass art. It's typically single-use and should be replaced after each firing.

Kiln wash can last several firings if it's not chipped or damaged—just touch it up as needed. On the other hand, shelf paper is usually designed for single use, especially after a full fuse. Inspect your kiln furniture before reuse to avoid project failure or equipment damage.
