Hard Ceramic Element Holders Make L&L Kilns More Durable

If you recognize these Broken Bricks and Sagging Elements:

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

Durability Rules

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.
