Why choose Warm Glass for your kiln?

What to Consider
Size & Shape
Consider the volume of work you wish to fire - if you're firing a few pieces each day then you'll need a chamber big enough.
If you're making jewellery or smaller pieces, choose a compact kiln like a Skutt Firebox 8 or Paragon SC2 - a bigger kiln can cost more to fire and take up valuable studio space.
For medium-sized projects, or daily firing of multiple pieces, consider mid-sized models like the Kilncare Hobbyfuser or Skutt Firebox 14.
Thinking of taller work, like drop out vases or deep castings? Choose kilns with deeper chambers such as the Hobbyfuser Drop-Out (exclusive to Warm Glass), the Cub-fuser Deep or the Pro-fuser Deep.
We sell kilns with different chamber shapes - square, rectangular, heptagonal, and bathtub - so you'll need to think about how your work will fit.
Finally, consider the logistics. Does it fit your space? Can you get it through the door? Larger kilns may require specialist installation.
Power Requirements
Controller Type
Make studio life easier with a great controller. The kilns we stock come with preset programs, to help get you started.
All our kilns come with digital programmers, which are recommended for ease and accuracy. The Kilncare and Nabertherm kilns also come with WiFi options, and an app, allowing you to control and monitor your kiln from anywhere in the world.
Consider how many programs and segments you need for your work. If you plan on exploring a wide range of techniques, you may want the ability to store more programs.
