In the May '99 issue of CM "Questions" column, Nils recommends ITC100HT for
kiln shelves. Are there various grades of ITC100, or is that just the
complete name for it? I thought I heard someone else on clayart say that
ITC as a wash didn't release well when dripped on? Who to believe?!!

I am wondering how much change there would be in my firing schedule if I
applied ITC to my kilns. Do they really fire faster? Currently I candle
from noon to evening reaching @ 300F. I leave the main burners on low
overnight and by morning it's usually around 1200-1300F, and then we start
firing in ernest. If I apply ITC am I going to get more rise overnight? I
really don't want any more rise...

First, the answer is no, not likely there would be significant difference
in your morning temp.
My question is...unless you are firing greenware, and you need to candle,
why are you firing untended (assumed) overnite? If you are firing bisqued
ware there is no good reason to candle and go so slowly. I suggest turning
it on in the morning with the burners on full (in earnest) and fire it up.
It will save fuel and time and be safer than having the burners on all
night. Nils

hello;

by itc i assume you mean itc-100.

itc-100 is an infrared reflector.
it is roughly 90 to 98 % efficient.

i use itc-100 for several reasons.

1. seals the ceramic fiber blanket so
that the ceramic fibers do not become
airborne.

2. allows for using a lower temperature rated
ceramic blanket, which costs less.

3. saves fuel, in my case propane.

you would see more rise overnight with a
coating of itc-100 than without. you should
be able to adjust the burners to compensate
for this.

while you do not state it, would it be save
to assume that this kiln is manual temperture
control?

ITC Experts
I've just finished putting Zirconium fiber in my Alpine updraft, 20cu
ft. I would like to start the pilots and dry it out, can I do this
before I spray ITC or do it all at once? Mike

Hi

I have decided to give ITC a try. I am changing elements and I am
wondering if it would be better or worse to spray the kiln while the
elements are out of the kiln. The directions say to just spray over
them. I will be using the two different ITC products, one for the
elements and one for the bricks.
