This is the “Thoroughbred” of kilns. Designed specifically for Crystalline Glaze firing - fast, responsive and precise.

The JH kilns were designed specifically for firing crystalline glaze. They feature special higher temperature firebrick for extra high cone 12 firing, extra power for fast heat up, super heavy-duty elements to hold up to the special rigors of crystalline firing, minimal insulation to allow for fast cool down, and type S thermocouples for long life.

Temperature Rating: Cone 12, 2400°F, 1315°C

Power Loading: These kilns come with approximately 25% more power than a regular kiln of similar size.
Loading: Lid position, when open, rests at an angle away from the kiln. Hinge: The hinge of the JD18-JH is not spring-loaded.

Stand: Heavy-duty 14 gauge full solid stand with multiple bends for strength. Bolt on legs.

Assembly: Two or three 9” high sections stack on top of each other. Easy to assemble. Bottom is reversible.
