Skutt Glass Fusing Kiln: Firebox 8 GMLT
This kiln offers all the convenience features of the FireBox 8 plus the GlassMaster LT3 Button Controller, which allows users to write and store up to five programs with up to eight segments each. It also includes the exclusive Skutt Glass Fire Mode — simply choose Fuse, Tack Fuse, or Slump, pick a speed based on the size and thickness of the project, and press "start."
Features of the GMLT FireBox 8 include an 8" × 8" × 4½" chamber, a "cool-to-the-touch" wood handle, and a stand.
Body lifts Off Base!
Sometimes when you are assembling a piece you do not want to risk moving it. The FireBox 8 was purposely constructed so the body of the kiln can be easily removed simply by undoing a buckle. This allows you to assemble your piece right on the shelf as it sits in the kiln and then place the body of the kiln back over it.
Plugs into standard, 3 prong, 120V household outlet
Includes a two-year manufacturer's warranty on parts and labor.

Plugs Into Household Voltage
Nothing against electricians, but who really enjoys paying to have their house rewired. With the FireBox 14 you take it out of the box, plug it into any spare 120V outlet you have in the house and you are ready to start fusing. Okay, it does need to be a grounded outlet.
Lid Opens Over 90 Degrees
Why is this important you ask? We are glad you did. When the lid can open past 90 degrees it will not be in your way when you go to load your shelf. That’s it!
