Kiln Brick
All Jen-Ken kilns are made of hand selected 2400°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 the brick
lid, the grooves that the elements are in and the
bottom of the kiln. This will 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
heigh
ts 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).
