Pros
- Runs on a household 120V outlet, no electrician
- Digital controller holds a real anneal
- Heats to fusing temperature fast in a small chamber
- Skutt dealer network for elements and service
Cons
- Small chamber limits plates and platters
- Twenty times the price of a microwave kiln
- Shelf and furniture sold separately
A small electric kiln with a programmable controller is what makes glass fusing repeatable. Glass does not just need heat; it needs a controlled cool through the anneal range around 900°F, or finished pieces crack days later. A microwave kiln cannot do that. The FireBox 8 can, and it does it on a standard household circuit.
Budget for a primed shelf and kiln paper on day one. Our kiln shelves and furniture guide covers sizes that fit an 8 in chamber.
Our Pick
The FireBox 8 is the small glass kiln we would buy first. It plugs into a normal grounded 120V outlet (NEMA 5-15, per Skutt), fires to 2000°F, and its 8 x 8 in chamber fits pendants, coasters, tiles, and small slumped dishes. About $1,500 at the time of writing, sold on Amazon through a Skutt dealer.
Buy it if you want real, repeatable fusing and slumping at home with a digital controller, and your pieces are 7 in or smaller.
What we don't like
The 8 x 8 in footprint caps you at small work. If you already know you want 10 to 14 in plates, skip ahead to the Hot Shot or a 14 in Evenheat.
