L&L E18S Kiln Shelf Kit
Optional Shelf Kit
Includes: Eight 25-1/2" Half Round Shelves (3/4" thick), Six each of 1/2", 1", 2", 4", 6", & 8" high 1-1/2" Square Ceramic Posts, Heat Resistant Gloves and 1 pound of Cone 10 Kiln Wash

Model JD2927-JH - JH Series Crystalline Glaze Kiln with extra power for fast heat up, K25 brick for reduced brick shrinkage at high temperature soaks, Quad Super Heavy Duty Elements, Multi-Program Three-Zoned DynaTrol, 2-1/2" brick sides and bottom and a 3" top for heat balancing and fast cooling, and type S platinum thermocouples. The panel on this kiln is a DaVinci panel with 50 amp power contactors and cords. 29" Diam x 27" High (10.3 cubic feet). This is the only standard kiln we use a side bar to support the lid (because the 2-1/2" brick needs that extra support). Direct power connection. Cone 12. The JH Series is specifically designed for crystalline glaze firing. (Not listed to UL499)

Features & Options
L&L Ceramic Element Holders DynaTrol Digital Kiln Controller Quad Elements
L&L Ceramic Element Holders
L&L Kiln's patented hard ceramic element holders protect your kiln. The ceramic element holder protects the soft fragile firebrick. Replacing elements repeatedly does not damage the brick. Elements don't sag or fall out of broken grooves. You do not need metal pins to hold elements into broken grooves. Customers often say their L&L kilns look new after 30 years of hard use!
DynaTrol  Digital
 The DynaTrol features Dynamic Zone Control. It is like having three controls in one. The DynaTrol separately measures temperatures in the bottom, middle and top of the kiln and automatically adjusts the heat output of three separate heating zones even as the kiln is heating up. Kiln temperatures are automatically evened out to within 1/2 cone or better top to bottom. There is no manual intervention with input switches.
Quad Element Design
The Quad Element System provides a massively robust element for long life under production conditions. Standard on eQuad-Pro and JH Series. Optional on most other kiln series.
APM Elements

Optional APM Sintered Power Metal Elements

APM elements increase element life in difficult applications. It resists grain growth at high temperatures and has a very high hot strength.

Vent-Sure ControlOptional Vent-Sure Control

The vent control allows you to automatically control the operation of the Vent-Sure kiln vent with one of the outputs from the DynaTrol or Genesis.

Genesis Controller

Optional Genesis Touch-screen Controller

Features: touch-screen for the user interface, easy-to-follow instructions, different user interface levels that can be set to match the user's firing knowledge, graphical display of the firing process, continuing use of decades of Bartlett expertise on kiln control.

Additional Features
  • Temperature Rating: Cone 12, 2400°F, 1315°C

  • Loading: Top Loading. Lid position, when open, rests at an angle away from the kiln.

  • Hinge: Spring loaded for easy opening while still allowing lid to be supported without supports that get in the way of loading with sidebar for lid support.

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

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

  • Construction: Stainless steel wrapped around shaped firebrick. There are three adjustable clamps welded to each casing. All assembly is with stainless steel screws. The kiln sections sit on a separate stand..

  • Insulation: 2-1/2" K25 firebrick, 3" Top.

  • Brick Coating: A proprietary brick coating is applied to all interior surfaces of the kiln. This is put on before the element holders are inserted. This coating penetrates the firebrick and fuses the surface on a microscopic level which helps prevent dusting and crumbling of the fragile firebrick.

  • Element Holders: Durability, Repairability, Better Heat Transfer. The smooth, hard surface of the inside ceramic channel allows the elements to expand and contract freely. No pins! The dense ceramic holders extend element life because they do not insulate the hot elements from the kiln interior.

  • Quad Elements: The Quad Element System provides a massively robust element for long life under production conditions.
    Standard on eQuad-Pro and JH Series. Optional on most other kiln series.

  • 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
    that mounts to the element connection boxes. Cords from sections plug into this
    panel. The control panel is hinged for easy access and maintenance. Control box can
    be easily removed for servicing. On/off switch and control fuse are included.

  • Control: DynaTrol with 4 Easy-Fire programs, 6 Vary-Fire programs, PreHeat, Delay, Program & Segment Review, and Diagnostics. Two programs can be combined for one 16 segment program

  • Zone Control: Two control zones with two separate thermocouples.

  • Peephole Plugs: Solid ceramic peephole plugs with full 1” diameter. Two total: one per section.

  • Thermocouples: Type S Thermocouple in an Alumina Protection Tube (4.75" / 120mm)

  • Relays: Mercury free relays.

  • Warranty: Limited Three Year Warranty (Note: The Element Warranty is modified for the JH Series - see the Warranty for details)
