These sound like the ones I use here in Japan, they are think
silicon carbide with the slits. Mine are 40cm by 35cm. I bought
them used (they were used in a factory pottery in Seto.) Cost me about
$10.00 each. I bought 40.

Hi:
I better mention that I don't have any sort of "trust fund" before I continue.
I have Crystars and Advancers. They are basically the same type of shelf
but are rated for different end temperatures due to differences in the
amount of nitride bond. Advancers are rated to 2600F and Crystars will go
to 2900F if my memory is serving me well.
I purchased most of the Crystars about 15 years ago when Norton was still a
US company and they were $95 each. We did a very large group buy. Later
on, a potter ran a credit line of10,000 bucks and got a super deal on
purchase for more Crystars. That time, we paid $105 a shelf. Still spendy
but within reach in the financial sense. I have about 40 shelves
total. First time I laid eyes on these buggers was when I took MacKenzie
out to Nils Lou's digs for some chow and a long chat. Nils had some then
and so did Warren, I think. I couldn't afford them at the time.
The big advantage other than fuel and space saving is almost no labor in
shelf maintainance and a lot less stress on the back when loading kilns. I
have never flipped these shelves and redo the wash maybe twice a year at
most. They are all totally flat and not the least bit warped. I fire
porcelain to cone 10-11 and it really helps the finished quality of the
ware to have very smooth, flat shelves.

Hi Tony, I saw the woman I buy my Advancer kiln shelves from an NCECA, her
name is Dona Turbes, email dona@ssfbs.com and she works for Smith-Sharpe
Fire Brick Supply. Phone # 1-866-545-6743. They are located in Minneapolis.
If you do a workshop here, maybe you could work something out. As part of a
large buy, possibly with other potters, these are now going for $135. I
checked the price with her, and that was two weeks ago. Good luck, Rikki

I got my 8 Advancers used for 80.00 each! I was happy. I have a very
light coat of kiln wash on them. My white stoneware sticks a bit. Hate
leaving bits of foot on the shelf..... But when glaze drips on them
it's very easy to scrape it off even with no kiln wash....

The rich folks out there have the fancy Advancer kiln shelves. Way to
expensive for those of us without trust funds. I'm testing thin silicon
carbide shelves for the local pottery supply house imported from China. What
is interesting about these 14" x 28" shelves is that they have 2- 6 inch
cuts into the length and 2- 3 inch cuts into the width. i figure this is to
prevent warping and possibly stress cracks. the word is these shelves will
be the same price as the high alumina clay shelves. I have been asked to
give them hell before they order from china. i will fire them in reduction
and then fire them wood salt.
If you are interested I will report to clayart about the fire and
mistreatment i give them. Put a burr in the bonnet of John Walls at Pottery
Supply House, Oakville,Ontario Canada that you just might want to be on the
list of people interested in the poor mans Advancers.

Good news for the working stiff.

Dear Daniel;
Plucking is when the porcelain pieces stick to the shelf or the wash,
when you remove them from the shelf. some of the foot stays on the
shelf. Really only happens with 'wet' clays.
Cheers, Hank

Hi Craig, Tony and all,
First, no trust fund here either.
I got three advancers to try, and am concerned about their possible
explosion. Craig, you wrote that you put kiln wash on them, and I was
wondering how you dry them before firing. Do you pre-bisque as the Mayor
recommends, or just dry them for a while? I would like to coat them with
kiln wash, as I fired one (unwashed) in the gas kiln and experienced
some plucking on the feet. The wash I use is half kaolin and half
alumina ox.
Is there anything dire I should know about kiln washing these shelves?
Thanks and best wishes,
Paul Herman

" Need something to plop a big fat 65 lb casserole in
the
middle of and not worry throughout the firing that my oldies are going
to
give up the ghost. Maybe the trick is to buy one or two a year."
Last year I bought one 24X24" advancer.
Perfect for some large pieces I was having
trouble with. Donna had a kiln shelf at
nceca that had been used in salt firings
for years. good news for me as i mostly
salt fire. a hardbrick rubbing takes the salt off the
unwashed shelf with little effort.

Dear Paul;
I use both Crystars and Advancers, used them nude with just a thin
layer of straight alumina oxide distributed with a grooved SiC block
evenly over the shelf. No plucking, no alumina oxide 'blowing' around
the kiln, easily reversible. Great!
Then I outsmarted myself by buying Tacoma Clay Art's Zircon kiln wash.
Sprayed thin coats on the shelves, dried in the sun, spayed more, dried
in the sun. Bisqued them with a long candling. Result? Plucking on
Grolleg porcelains, wash began to chip off almost immediuatelty, can't
reverse them, felt stupid after 46 years potting!
Got new Advancers recently.........distributing 80 mesh alumina oxide
with the grooved SiC block, no plucking, can brush off the oxide to
reverse, I am happier and wiser, but nbo one will believe me. They say,
"The Alumina will get all over your work in the firing!" I smile and
say, "Your Mileage May Vary".
Cheers, Hank in Eugene

So now I find out Hank has the Advancers. Lucky stiff. That's why his
tiles lay flat. If tourism gets back on track i might buy one or two for the
back of my kiln. Need something to plop a big fat 65 lb casserole in the
middle of and not worry throughout the firing that my oldies are going to
give up the ghost. Maybe the trick is to buy one or two a year. the thought
of buying 30 at at $300 ($12,000 Cdn) US a pop is just too frigthening. Hell
I could put a nice porch and deck on the house and maybe even take a trip to
Scotland.
Spend all my money on the pottery as it is. Time for me to spend it on a
hot tub or something.

Dear Daniel,
<>
It is a condition where a vitrified footring adheres to the shelf
surface and during cooling differences in contraction cause small
fractures in the footring. This leaves razor sharp fragments of your
pot welded to the shelf surface.
Very, very dangerous. Slice into the unwary hand. Result, copious
amounts of red stuff .
Best regards,
Ivor Lewis. Redhill, South Australia
