element changes.
L&L’s Quad element system
features four rows of elements
in each 9" high section. Quad
elements are wound with thicker
guage wire and have a lower
watt density than standard
elements. With coils measuring
almost ½” diameter, these heavy
duty elements stand up to the
rigorous demands of Cone 10
crystalline firings.
Easy to program DynaTrol
Controller has (4) Preset
Programs for standard firings
and (6) User Programs for
custom firing profiles. Custom
programs allow control of heat
up and cool down, heat soaks
delay start and more.
Perfect for Crystalline glaze firings.
Multi Zones keep the chamber firing
evenly top to bottom. Special
Type S Thermocouples give more
accurate readings at Cone 10.
Spring assisted hinge
makes opening the lid easy
and supports it securely.
The hinge opens beyond 90
degrees for easy access to the
chamber while loading and
Sections are completely separate
from the Control Panel for easy
disassembly when moving or
servicing the kiln. Each section
has a cord that plugs into a
receptacle on the main panel.
Once unplugged, the main panel
can be removed and the sections
separated. (*NOTE: The kiln hinge
system must also be removed for

L&L’s JH Series Crystalline Glaze Kilns are designed for Cone 10 Crystalline glaze firing. They have extra power and higher temp rated brick for a maximum rating of Cone 12. Features include K25 firebrick, Quad Super Heavy Duty Elements, Multi-Program Zoned DynaTrol, 2-1/2" brick walls and floor and a 3" lid for heat balancing and fast cooling, and type S thermocouples for more accurate readings in the Cone 10 range. In addition, JH kilns also feature a proprietary brick coating to harden and seal the soft firebrick, full-size (not tapered) 1” spy holes for easy viewing of witness cones, protection tubes for longer thermocouple life and corrosion-resistant aluminized steel stands.

This version of the JD2927-JH features the JD style ‘Plug-In’ Control Panel. Kiln must be Direct Wired and comes without a cord or plug. See ‘Specifications’ for dimensions and electrical requirements.

Electrical Specifications for Kilns

The chart above lists the available electrical specification options for this kiln. You must order the kiln with the proper wiring specifications for it to function properly. These specifications are determined by the power supply that you will be connecting the kiln to. Review this information with your electrician to determine the proper Voltage and Phase for your kiln. The choice of V/Ph determines the Amperage draw of the kiln and the size of the breaker needed. A kiln requires a breaker that is 20% above the actual amperage draw. Be sure that you can supply sufficient power for the kiln you choose. The chart also indicates the NEMA plug configuration for the kiln –or- if it must be Direct Wired. Voltage and Phase selection must be confirmed in writing with all kiln orders. If you have any questions concerning this information, please call us at 800-431-6067.

Thank you.
