At John Abbott College here in Montreal we have been using high Alumina shelves
(made in Britain by Acme Marl)for many years. We have been buying them from
Tucker's Pottery Supplies in Ontario (I-800-304-6185 US as well as CA). Before
that I used them in England in my oil kiln. They are excellent.
Frank, it's good to see you on Clayart, you've got to stop that lurking!! :-)

Before you chip at the shelves as best you can with a chisel, sprinkle
alumina hydrate onto the frozen puddles and put these shelves into your
next (high) firing. The alumina enters the glaze pool and makes its
texture a little "sugary" and much easier to eliminate.

just note to followup jonathan....it is not always necessary to have all
light weight shelves...all of the lower shelves and front shelves can easily
be sil.carb. i use up many of my heavy shelves for base and low bearing
shelves. i keep 6 big super tech shelves for the top and back when it is
difficult to place. whithout question i have shelves that are 30 years old
and are just fine. i would never replace or "get rid"of any of my shelves.
and then there is the odd chance that you may make a second or third kiln
and will need them.. i have gathered shelves from people "leaving the
pottery business" and have a wonderful collection of mismatched, odd sized
and weird shelves.. but they all work, and often with a strange stacking,
the perfect shelf.
i insist on spending money on good tools, but look into it..nose around, the
claynet can be your best "consumer report" mel/minnesota

Mel, and any others who are listening---
You say "three point posts are the best", however, our shelves are all slumping
in the middle, and we use three point posts. What are we doing wrong?

Hmmm, Douglas Adams, interesting approach to de-glazing shelves. I'm
very tempted. Stop me, somebody, please ... Now, does anybody know if
it's possible to de-warp high alumina shelves?? Don't ask... I firmly
believe that you'll never know if you don't try, and you clayart buds
encourage that attitude ... you know you do ... thank goodness.

Sandra,
(In an ideal world) starting with new shelves, fire them one way up
first time 'tother way up second time, and so on. This requires serious
mental organisation or marking the next side up with a pencil when
unloading. What about Batt wash I hear you cry, answer: sieve fine
molochite (calcined china clay) or Alumina Hydrate onto the working side
before loading. After the firing tip back into a bucket ready to sieve
and use again next time.
Phew! time for a large Gin I think!

i have removed the mess from my kiln.
have done some serious analysis and have some conclusions to
share with you all.
my first mistake was to start a tower of plates using one post
on the far end, and two on the near end with the plate in the middle.
that works fine, but the base shelf had the two posts on the sides
and one in the side middle. it was opposite the rest of the tower.
a simple `shit, i forgot to change the base shelf.`
also, i have three base shelves that were given to me with about
10 others...can't think of the name, pure white, thick, heavy. they
are prone to cracking under heavy loads. it has happened to me
before about 15 years ago. (the full set of dishes, service for 14 in
one kiln load, plus accessories.) that is when you use every kiln shelf
you own or can borrow.
so, what i have done is:
went into my stash of new shelves. have 10 of them hidden. silicon carbide
the same as the rest. did the full coat of itc 100 and have replaced
the white base shelves with new silicon carbide dandies.
put up a note on the wall. `hey, dorko, don't forget the base shelves.`
hit myself in the face with a ruler. made myself lie in the snow naked
for fifteen minutes. went to bed without dinner. felt extreme guilt
and shame. now all better.
i really do stand by my former remark. kiln shelves will often crack
and stop, and will no longer crack. you can use them for years.
i always try and put my furniture under the crack when possible.
my tower of shelves toppling was not due to a previously cracked
shelf. it was perfect when i loaded the kiln. it was due to `pilot
error`. the weight of that tower on top of that unsupported shelf
caused it to split in three pieces, in turn breaking the shelf above
it. it was a good lesson to learn.

Dear Mel
Coincidence, I expect not . With the number of people on this list
firing kilns statistically there has to be at least two of us doing
something stupid with kiln shelves every day.
The other Idiot doing what he knows not to do and would scoff at others
doing what he has done is yours truly .
An Australian potter moved near here a couple of years ago and not
getting on with the weather decided to move and coincidentaly one of my
evening class students moved into the house she vacated . The Australian
left some slip cast clay pieces behind including a cheese dish which my
student turned up with asking me if I can fire it.
At this point every self respecting potter on this list knows the
disaster that this is shaping up to be .
But vanity is an awful powerful force. I looked at the pots ,lid and
base, and said confidently they are porcelain and we can try them in the
biscuit kiln. They came out of the biscuit kiln with the same absorbency as
the other pots. I was on a roll, so I glazed the things up in blue ,and just
in case they slumped a bit I did not glaze the bottom.
Fired it up to 1275c oxidize.
There it was the lid and the base in a blue pool spread over two
kiln shelves all completely vitrifyed to a glass. I chipped it off with a
coal chisel a lot of kiln shelf came away with the molten mess , modern kiln
shelves are soft and stand so much more miss treatment than the more
vitrifyed ones from the good old days.
And being so unnerved by the experience I dropped a vase when I was
moving some of the pots that the molten mass did not stick to on kiln shelf.
Monday is the day of reckoning. I would spend two hours flagellating
myself in the snow not to have to face those students.
Humble pie sticks in the throat.

Nah, it won't stick in your throat. It may be that it is an acquired
taste. But then, I've had lots of practice trying it. It's not too bad
with the proper sauce.
And think how much the students will learn: what can happen, will happen;
clean up the mess and go on, it ain't that big a deal.
How boring life would be
if everything we did went perfectly, no mistakes or disasters ever happened,
and learning was a smooth, gentle, perfect curve.
There'd never be any good material for stories. And this one's a gem.

I think the punishments are not good enough - only last 10 years. I have
better ones - last longer.
Self inflicted ones are never the best. Better to have someone else make

Hi Barbara,
Well I thought things were getting a little too serious so I had to do it -
the devil made me.
Glad you had a good laugh - it's why I did it - funny - Mel is not asking
for my suggestions - been making them up just in case.
Ron.

For Christmas my kids would like to buy me some pottery supplies. I would like to have new kiln shelves since mine are all messed up. I have a Skutt 1227 model and fire usually at cone 6. I had seen a while back in some ceramic magazine an advertisement for shelves that are thinner, stronger and lighter than the norm. I can't find that magazine. Does anybody know what those shelves are called and where can I purchase them from? I would appreciate any feedback on this.

A full shelf (23" dia.) goes for about $50US
