I am the proud owner of a "new" used Paragon electric kiln. It came with
four 5/8" half shelves (diameter 20"). I plan to fire to cone 10, but I am
only a part time potter, so will probably only go this high once or twice a
month.
After reviewing the rave reviews on ITC in the Clayart archives, I am
planning to coat the kiln, shelves and posts with ITC. Here are my
questions:
1) If I coat the 5/8" shelves with ITC, can I take them to cone 10, or will
I need to buy 1" thick shelves?
2) Does anyone have any cheap sources of shelves, or should I just buy them
locally, to save in shipping? (BTW, I live in Dallas.)
3) My kiln is 5.10 cubic feet. Will a pint of ITC 100 be enough to cover
both the shelves and the kiln?
4) I understand that the ITC comes off with your stuck pieces, so over time
I will need to reapply in places. Does it have a "shelf life", or can I buy
extra now for the inevitable patches?
5) For such a small application of ITC, it seems expensive to buy the
sandblaster sprayer and rent a compressor. I know that brushing it on is not
recommended. Is there a cheaper way to spray it?
6) Finally, a non-ITC question. Someone told me that you should put your
first layer of pots on a shelf at least 7" from the bottom of the kiln. I’ve
always fired with a shelf just an inch or two off the floor of the kiln. Is
this person correct?
Thanks!
Julie Ryan

I use 2" or 3" posts on the bottom of the electric kiln, that
should be sufficient. =20
Re: shelves - I have not had good luck using kiln shelves
from the Dallas area. The only ones I've found there are
made in Mexico, and quality control is poor. Too many have
cracked first firing, no reason that was apparent. The
offer was made to replace the shelves, but - I just got a
credit, bought shelves elsewhere - specifically, Thorley
Refractory, out of California, phone 562-633-2647. No
problems, ever, and this is a teaching situation. Wherever
you get your shelves, be sure to specify for Cone 10.
You CAN brush ITC on, but it is more difficult to get it
on thin & even. ITC keeps, if you re-seal the can. For
coverage, call ITC company, and ask Alice.

Dear Julie,
I spray ITC with a $20 sand blaster hooked up to compressed air (already
have compressor). I sprayed a new fiber kiln 2X2X2.5 feet. ITC is
supposed to be diluted with water. I mixed water into it with a jiffy
mixer. Sprayed a nice coating with the sand blaster after dampening the
fiber.=20
Bricks are also to be dampened first.
I didn't use much ITC. -much less than a 1/4 gallon liquid (1 pint water
and 1 pint ITC)
ABout the 7" from the floor. For electric kilns this is not necessary. I
agree with you 1-2 inches only.=20

Hi!
Try Paragon's shelves. They have a new provider and the shelves are rated
cone 12.
