I'm gathering information on kiln coatings on behalf of Peter Meanly.a
potter in Belfast,Northen Ireland.Peter is doing research on the long range
effectiveness of kiln coatings for salt kilns. He intends to fire at least
100 salt firings for each coating tested.He is aware of ITC coating,but
would like to test any other commercial or homegrown coating that may be
effective. If anyone out there can help,please reply on the list or to me
at b-chesser@onu.edu

Two refractories have been recommended to me as kiln coatings for a ^10 R
kiln. Has anyone had experience using these: KS-4V Refractory by Harbison-
Walker Refractories Co. or LW2200 by Reno Refractories in Morris Alabama? I
am looking for an alternative to ITC as a kiln coating.
Thank you in advance for your response. Caroline

Caroline,
If you are troweling or painting the KS-4V, that's fine. If you are going to
spray it, you might want the KS-4V GR. The GR stands for gunning refractory
and has better flow characteristics through guns. I'm not familiar with the
LW2200 from Reno. Are you sure that's the right designation? LW2200 is the
designation for a insulating brick made by Newcastle refractories (a division
of Dixon-Ticonderoga). Good Luck and let us know how it works for you. I've
not used the KS-4V in this application, but don't see why not. It's a low
iron, negligible shrinkage, 2600F/1425C castable. It's basically a fire clay
with bonding and hardening materials. It will form a hard, durable coat.

Re: ITC bonding.....for various reason I had to dismantle the top of a Minn
Flattop last summer. It had been sprayed with a thin coat of ITC 100 and
fired maybe 50 times to cone 10. The brick face where the ITC was sprayed
was bonded together and back into the brick maybe 1/2 inch. It was almost
like a glaze layer. In many cases, the bond caused the brick edges to stick
together and the IFB broke away from the bonded faces and edges. Have tried
using Greenpatch and other bonding cements and they spall and chip off.
ITC, properly applied does not.

As long as we're on this subject, does anyone know if using a thinned High
Temperature Bonding Mortar to seal the inside of a softbrick kiln would work
like ITC. I would not spray the shelves and burners like Mel with ITC, but as
a sealer it seems that the mortar would accomplish the same purpose.

Nils Lou on thu 27 jul 00
John, I'm unsure what you mean by "sealing the inside" or why you would
want to, but bonding mortars and most other refractories that might be
used to coat are, and work totally differently from ITC materials. ITC
100, for instance, when applied and heated is no longer a coating. It
interfaces with the material and an entirely new material is created
connecting the surface with the IFB, for instance. This bonding interface
is why, if applied properly (meaning a thin coating) there is NO spalling
of the ITC product. So, the answer to your question is no. Simple bonding
mortars and alumino/silicate zircon mixtures will not function like ITC.
They will remain isolated coatings like paint on wood.

While Nils speaks with the voice of an authority, I speak with the voice
of bitter experience.
Three years ago I built an Oregon Flat Top with a hinged door and coated
the inside of the door with GreenPatch 421 to make it nice and smooth. Now
the door is going to have to be rebuilt because the GreenPatch is falling
off, taking part of the bricks with it, while the inside of the kiln which
was sprayed with ITC 100 is in fine shape.

John,
I use a mix of 1 part kaolin to 3 parts alumina hydrate and 2 parts silica.
I've had no problems with peeling or spalling so far (12 years) in my
catenary arch built with NARCO r28 insulating fire bricks.
Feri,
Back on line after a system rebuild due to a lightening spike. Autumn and
Monika, If you are still out there, could you send your E-mail addresses?

Hi,=3D20
I have been reading most of the posts on kiln coatings over the last =3D
year. I am still wondering if any kiln coatings have proven effective =3D
over time in wood fired soda kilns? This would be on a new hard brick =3D
kiln with a K23 brick door. Any input is appreciated.
Thank you,

This article seems fairly conclusive for salt kilns. Everyone says Soda rea=
cts differently on SiO2 than salt does, and wood reacts in a similar manner=
on SiO2 as does salt. So I'm not sure if this article will help for soda o=
r not.

Hi Jeff -
You don't need any protective coating on the hardbrick, but it does help to
give the hardbrick surfaces other than the floor a fluid, saturating spray
coat of any shino glaze before the first firing. That just hastens the
development of the surface that would form anyway. As far as the door goes=
,
we had excellent luck with a homemade protective coating formed of 45 parts
zircon flour, 45 parts aluminum oxide, and ten parts kaolin. Mix it very
watery and apply several coats that can soak into the surface of the brick.

deal with it...
not a big deal...many years ago....or five years ago here
and dealt with it in 1995 in Bennington Vermont. long ago.
