Common questions
What's the difference between fusing and slumping in this kiln?
Fusing joins pieces of glass together flat on a shelf at approximately 1450-1500°F, while slumping shapes fused glass over or into molds at lower temperatures around 1200-1350°F. The HS-7GW handles both processes with its programmable controller—you'll set different ramp rates and hold temperatures depending on your project. For fusing, you'll typically ramp quickly to tack or full fuse temps; for slumping, slower ramps prevent thermal shock to pre-fused pieces.
Can I plug this into a standard household outlet?
Yes. The HS-7GW draws 15 amps at 120V and plugs into a standard 15-amp household outlet. Avoid running other high-draw appliances on the same circuit while it fires, and make sure the outlet is properly grounded. Never use an extension cord or power strip with this kiln.
What size glass pieces can I fire in the HS-7GW?
The 7-inch square chamber accommodates pieces up to approximately 6.5″ × 6.5″ to allow clearance from the walls. This is ideal for test tiles, jewelry components, small plates, cabochons, and pendants. You'll need to account for shelf posts if stacking, which reduces usable height. For production work or larger pieces, consider Hot Shot’s HS-12G or HS-16G clamshell glass kilns, which have bigger chambers.
How long does a typical fusing cycle take?
A full fuse to 1500°F typically takes 3-4 hours including annealing, depending on glass thickness and your programmed ramp rates. The lightweight ceramic fiber insulation heats quickly—expect approximately 20-30°F per minute on initial ramp. Annealing soak and controlled cooldown add 1-2 hours. The compact size means faster cycles and lower energy consumption compared to larger kilns.
Why buy from an authorized dealer like Peach State Pottery?
