Common questions
What glass applications can I do in the 189 Slider?
The 189 Slider is designed for fusing, slumping, and annealing glass up to 1700°F. The 18×18-inch floor accommodates full sheets or large glass projects, while the 9-inch height provides clearance for slumping molds and multi-layer fusing. The sliding floor design makes it particularly well-suited for loading delicate glass arrangements without disturbing your setup.
Do I need an electrician to install this kiln?
Yes. The 189 Slider requires a dedicated 240V, 30-amp circuit with a NEMA 6-30 receptacle and 10-gauge wiring. We strongly recommend hiring a licensed electrician to install the circuit according to local electrical codes. The kiln can also be wired for 208V in commercial settings where that voltage is available.
What kiln furniture do I need for glass firing?
You'll need kiln-washed shelves designed for glass work, fiber paper, and slumping molds depending on your projects. Standard ceramic kiln shelves work but must be properly prepared with kiln wash or fiber paper to prevent glass from sticking. We recommend purchasing a glass kiln furniture kit that includes shelves, posts, and fiber paper specifically sized for the 189 Slider.
How does the sliding floor mechanism work?
The clamshell lid lifts open while the floor slides forward on rails, extending 44 inches out from the kiln. This allows you to load and unload projects at waist height without reaching over hot elements. The sliding mechanism is smooth and stable, keeping your glass work level during loading and eliminating the awkward overhead positioning required with top-loading kilns.
What's covered under the Olympic warranty?
Olympic provides a one-year limited warranty covering defects in materials and workmanship. The kiln must be registered within 30 days of delivery, and the warranty is valid only when purchased through authorized dealers like Peach State Pottery. Elements are considered consumable items and have limited coverage. Proper installation and maintenance are required to maintain warranty coverage.
