Hard Ceramic Element Holders Make L&L Kilns More Durable
If you recognize these Broken Bricks and Sagging Elements:
A typical non-L&L kiln without hard ceramic element holders showing how the brick breaks and elements sag from from constant loading and wear.
Then you Understand the value of an L&L Kiln with a clean Interior:
This is an untouched photograph of an L&L Kiln from 1968 that a customer sent us.
Hard Ceramic Holders Protect Firebrick
- The hard ceramic element holders protect the soft fragile firebrick
- Replacing elements repeatedly does not damage the brick
- Elements don't sag or fall out of broken grooves
- No metal pins are needed to hold elements into broken grooves
- Customers often say their L&L kilns look new after 30 years of hard use!
Smooth Hard Surface of Holder allows 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
Dense Ceramic Transmits 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 insulating ability, energy efficiency and strength of the kiln
Cost of Maintenance
- How hard are you going to use the kiln?
- If you are a school, an institution, a factory or a serious artist who depends on your kiln for a living, then you should seriously invest in the most trouble-free kiln you can buy.
- Even if you are hobbyist why not get the best kiln made?
- Although the exact cost of maintenance savings is hard to calculate - it can add up to major savings in time and money.
Ceramic Holders Fixe the Fundamental Problem of Electric Kilns
- Most electric kilns have grooves routed in the firebrick for the elements to lay in.
- The elements are often pinned in for further support.
- The firebrick "wall" that supports the element also insulates the heat of the element from the kiln (creating energy efficiency problems and element life problems).
- After one or two element changes 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.
Replaces troublesome Metal 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.
