ITC
ITC products are high refractory coatings used for coating the inside
of kilns and elements. Benefits are lower energy costs, faster
firings, and less wear and tear on your kiln. ITC products are
used extensively in industry in applications from commercial ceramics to
the space shuttle. Nils Lou, in "The Art of Firing"
writes "The ITC coatings are as technologically significant as the
development of the insulating brick." |

ITC
100HT Ceramic Coating
 |
Use: To save fuel and to repair and protect all kiln interiors make of
brick, castable, fiber blanket or fiber board and burner blocks and burner
tips. To minimize glaze sticking on kiln furniture, such as setters,
slabs and pins.
Prepare surface: Remove all debris, loose particles, dust, etc. from
interior walls, door, crown and grooves behind electrical elements.
Vacuum if possible. (It is recommended to clean you elements with a
water/bleach solution and toothbrush prior to spraying ITC.)
Mix: To one pint of ITC100HT add 1/2 pint of water and mix well.
To one gallon of ITC100HT and 1/2 gallon of water and mix
well.
Apply: Immediately before applying coating, dampen the areas by
spraying lightly with water. Then using a spray gun, apply a thin
coat on the dampened surface. A brush can be used for small areas,
dipping the brush into the water first each time. Spray or brush
through elements. Spraying is preferable. (Note, it is
important that you get the coating on thin. You may experience
peeling the first few firings, especially if the coating is too thick, so
your first firings should be bisque.) It is also important to keep
stirring while you apply, because the product settles out. So it is
better as a two person job.

213 Ceramic Coating for Metals
 |
Protect your elements even more. ITC213 will protect all metal parts
from oxidation or reduction and other harsh environment such as high
temperatures and proximity to molten metals, molten glass or
glazes.
Prepare Surface: Remove any metal scaling,
loose rust, grease and dirt. Also remove any paint on the surface of
the metal. Sandblasting is not recommended nor using any kind of
solvent such as kerosene, alcohol, etc. Use a wire brush, file,
hacksaw blade or grinding wheel if possible. Rinse with plain water
and wipe with clean cloth.
New elements have a greasy residue left from the wire manufacturing
process, which may cause the ITC 213 to flake off if not removed.
One method is to pre-fire elements after stretching for 5 to 10 minutes to
achieve at least cherry-red glow. If this is not possible, the
elements can be heated in a furnace or kiln at 700 degrees F for 30
minutes. Allow to cool. (note: Some potters have recommended washing
the elements with a 1:1 solution of liquid Clorox bleach
and water.)
Apply: Mix coating thoroughly and apply
using a short bristle medium hard brush or foam paint edger or a
cloth. For large areas use a cup spraygun, available below. In
caes of spraying it is necessary to dilute the ITC213 as follows: to 1
pint ITC213 add 1/3 pint water and mix well; to 1 gallon ITC213 add 1/3
gallon of water and mix well. Probably the best method for applying
ITC213 to elements is to dip. Using a wide shallow pan, such as a
wallpaper tray, empty the ITC213 into the pan and add 1/3 water, mixing
well. Dip the entire element except for the lead wire into the
mixture. After dipping, shake the element to remove excess coating
and hang to dry for several hours or overnight. The elements are now
ready to install.

ITC
296A Ceramic Top Coating
A high purity coating which gives a clean firing and minimizes impurities
in glass kilns and molten metal operations. This is used to obtain a
higher degree of purity which firing porcelain, jewelry, glass, and other fine
items. Further enhances kiln performance and increases longevity of
electrical elements. ITC 296A is applied OVER ITC 100HT.
Prepare Surface: Apply ITC 100HT and
ITC200EZ as directed and fire kiln at least twice with these in place.
Mix: To one pint ITC 296A add 1/2 pint of water and mix well.
Apply: Spray or brush entire surface, including elements.
Spraying is preferable.

recommends this one. Originally designed for sandblasting, it's
simple, tough and works well with ITC materials. Easy cleanup with
air or water.
Operates at 80 - 120 PSI and has a 1/4" NPT air inlet. Comes
with a pickup tube, 10 ft of siphon hose and 2 extra nozzles.

200 EZ Ceramic Repair
Excellent for repairing broken, chipped or cracked brick or burner blocks,
castable or fiber material and for filling in crevices.
Prepare Surface: Apply ITC 100HT and patch
with ITC200EZ while wet.
Apply: If necessary, thin with ITC100HT
as prepared above. Using a spatula or similar tool, simply fill all
cracks, holes, crevices and damaged areas, including areas behind
electrical elements in need of repair. Allow to dry.

| (Note: Many users of ITC are members of the
ClayArt internet user group, where various users share their experiences
with applying it. To help you understand the process of applying
ITC100, you may want to read these recommendations from an avid user:
"I have found that thinning a quart to a quart will
work just fine. It is important to mix it well and keep it mixed
when spraying. I suggest a second person to stir. It will
settle very fast. I like to keep the feed pail high...like on a
ladder top. Let gravity work. It will take about ten minutes
to spray an electric kiln. Also, it will smoke a bit on the first
few hours of firing. It is just the adhesive burning off. Typical
venting is just fine. Open windows, etc. a fan always helps. Remember
the inexpensive sand blasting spray gun works the best. You will
need 40-50 lbs of pressure, and a bigger spray system works well, as
pressure drops very fast. You can spray for a minute or two, let the
compressor catch up.
A thin even coat is best. Thick and blobby is bad.
Spray right over the coils, thermocouple... everything. Give it a
nice even, thin coat. One can see very clearly where you have
sprayed. Turns a rich gray.
Remember, unplug and wash your kiln before you spray. I know, that will freak
many folks...but i use the spray gun and spray the entire inside of the
kiln with pressurized water. Cleans that puppy like a dream. After
you spray, let it air dry for a few hours...then turn it on low....for
about an hour. Then to high for about 15 minutes. It will smoke and
puff for a bit, then just turn it off, and look forward to many firings.") |
