L&L CONE 12 KILN: JD2927-JH for Crystalline Glaze FiringL&L JHZ and JH SERIES KILNS: CONE 12 Kilns
 L&L JHZ and JH SERIES KILNS: CONE 12 Kilns4 basic sizes (plus custom models) in each line.SEE COMPLETE SPECS IN CHARTS BELOW
The JHZ and the JH kilns are designed to go to higher temperatures than standard kilns. They feature special higher temperature firebrick for extra high cone 12 firing, extra power for fast heat up, super heavy-duty elements, type S thermocouples for long life.
These kilns were designed with Jesse Wiseman Hull.

The JH Series is the 2.5" BRICK VERSION : recommended for crystalline glazes.
The JHZ are the 3" BRICK VERSIONS : recommended for other high temperature work except for crystalline glazes.
The JHZ Kilns also have additional 1/4" ceramic fiber barrier insulation between the brick and the casing.
FEATURES of the JHZ SERIES KILNS
-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 JD18-3-JHZ is not spring-loaded.
-Stand: Heavy-duty 14 gauge full solid stand with multiple bends for strength. Bolt on legs.

-Construction: Stainless steel wrapped around brick with 3 clamps on each section. All stainless screws.
-Insulation: 3” K25 firebrick on the sides and top. Bottom is 4-1/2”. There is a 1/4” ceramic fiber barrier between the firebrick and the stainless steel case.
-Brick Coating: Proprietary brick coating included.
-Element Holders: Hard ceramic element holders protect brick.
-Quad Element Design: Super Heavy-duty, thick elements with 4 wraps per 9” high section.
-Element Connections: Proprietary all-ceramic element connection block makes changing elements easy.
-Control Panel: All controls and components are mounted in a separate control panel. Mounting and type of panel vary with model number.
-The control panel and element box are hinged for easy access and maintenance. Control box can be easily removed for servicing. On/off switch and control fuse are included.
