FIBER KILNS

Fiber kilns can be constructed in any configuration. They can be top load, clamshell, or front load. They can also be hybrid kilns and contain brick bottoms or walls.

Glass fusing kilns or ceramic and pottery kilns made of rigidized fiber will heat and cool faster than brick kilns. A ceramic fiber kiln is great for producing lots of fused work quickly, as you are not hanging around waiting for the bricks to lose their heat, allowing you to cycle kiln loads even faster.

A fiber kiln is also a good choice as a travel kiln or portable teaching kiln, as it is light and usually constructed in one piece. Another benefit of a fiber kiln would be its weight. A lighter kiln may be necessary in buildings that have flooring load concerns, for example, loft spaces, pier and beam construction, or elevated construction sheds, etc. If you plan to produce a lot of very thick work, a fiber kiln is not a good choice for you as it will naturally cool too quickly, requiring you to use more power to keep up with the temperature requirements. A fiber kiln will remain cleaner due to its extruded construction and lack of joint expansion.

    Frequently Asked Questions

    Frequently Asked Questions for Fiber Kilns
    What is a fiber kiln?

    A fiber kiln is built with a ceramic fiber chamber rather than firebrick. The fiber insulation is lightweight, heats quickly, and stores little heat, making these kilns energy efficient and well suited to fast firing, glass work, and high temperature applications.

    Are fiber kilns good for high temperature work?

    Yes. Ceramic fiber kilns are designed to reach and sustain high temperatures efficiently, which is why they are popular for heat treating and demanding firing schedules. Always check the listed maximum temperature on each model to confirm it meets your needs.

    What is the difference between a fiber kiln and a brick kiln?

    Fiber kilns use soft ceramic fiber that heats and cools fast and weighs far less than dense firebrick. Brick kilns hold heat longer and resist physical wear better. Fiber is ideal for speed and efficiency; brick suits long, heavy production firing.

    Can I use a fiber kiln for glass fusing?

    Many fiber kilns work well for glass fusing and slumping because they ramp and cool quickly, which helps with controlled glass schedules. Confirm the chamber dimensions and temperature range fit your glass projects before purchasing.

    Is ceramic fiber in a kiln safe to handle?

    Ceramic fiber and fiber paper can release fine particles, so wear a respirator, gloves, and eye protection when handling or replacing it, and follow the manufacturer's safety guidance. The fiber itself performs safely during normal firing inside a sealed chamber.
