Kiln Brick
All Jen-Ken kilns are made of hand selected 2300°F
refractory brick. The brick is strong as a whole and has a
very long life. The brick can chip easily and care should be
taken to avoid bumps while loading and unloading shelves.
Frequently vacuum, using a soft vacuum brush, the brick lid,
the grooves that the elements are in and the bottom of the
kiln, will keep ashes from the shelf paper out of the kiln. This
will also remove the dust, sand and loose kiln wash from the
kiln.
Kiln Jacket
Your kiln is encased in a stainless steel jacket and is also equipped with handles for easy
moving. Due to the high temperatures, discoloration may appear on
the stainless jacket. A good metal polish will remove this discoloration.
Accessories
Shelves:
Shelves help you make the most of the inside for your kiln. Shelves are sized a few
inches smaller than the inside diameter of the kiln so that they can be placed in and out of the
kiln more easily. They are made of refractory material so that they should be handled carefully.
Should a crack appear in a shelf, break the shelf along the crack and use it as two separate
pieces. A good coat of kiln wash should ALWAYS be maintained on top of the shelves. Store
shelves upright on edge, leaning on a sturdy structure, not flat on their sides. Shelves stacked
flat can put too much pressure on the bottom shelf and cause it to stress and crack. Store
shelves that are not in the kiln on edge.
Posts:
Posts are also made from refractory material and
should be handled carefully. Post sizes range in heights
from ½” to 14”. They are used to support the shelves in your
kiln at different levels depending upon the height of the
pieces you are firing. Usually, three posts allow you to level
the shelf more easily (although some fusers prefer four).
