The inside of an e23T-3 L&L Easy-Fire Kiln.
Protect Firebrick and keep interior clean
-
Replacing elements does not damage the brick
-
So easy to do - you can change elements WITHOUT unstacking the kiln
-
Elements don't sag or fall out of broken grooves
-
Element Holders are hard - they resist breakage when loading
-
Customers often say their L&L kilns look new after 30 years of hard use!
Allow elements to expand and contract
-
Ceramic element holders have a smooth, hard surface which allows the elements to expand and contract freely
-
No loose brick particles will fall in the kiln and ruin ware
-
Your elements will last longer because elements do not get easily snagged, bunched up, and burned-out
-
It is harder for glaze, clay particles, and firebrick to touch and damage elements
Transmit Heat Better
-
The thin, dense wall of the holders reflects the infrared heat into the kiln
-
Elements operate at a lower temperature relative to the internal kiln temperature
-
L&L kilns require less firebrick insulation to be cut out which increases the insulating ability, energy efficiency, and strength of the kiln
Fix the Problem of Electric Kilns
-
After one or two element changes, without ceramic holders, the fragile firebrick starts to fall apart and pins become the primary element support.
-
It only takes one accidental bump with a kiln shelf to permanently damage a kiln around the element groove.
Don't require pins
-
Pins can actually make the problem worse because as they expand and contract (at a different rate than the brick) the pins fracture the firebrick more.
-
How do you know before you start how many you are going to need?
-
It is very difficult to find places to put the pins, as the firebrick is so deteriorated and crumbling.
-
Crimped terminals are a pain to install and, as the wires have to keep getting cut back, the wires get too short.
Save Money on Maintenance
-
You could save $300 the first time you have to change your elements because, on an L&L kiln, you can do it yourself instead of paying an expert - it's easy!
