on a warm day in december.
almost 45 today. that is f.
was just wondering, how i think about
the pots as they go in the kiln.
`hey, this one ought to be really nice on friday.
or, these plates had better match, or damn, is
this glaze thin`.?
and on and on....we have such hopes for them, such
ideas of grandness...and then friday comes, i open the kiln..
and often the favorites are plain, the plain ones become stars.
never know.
just like potters, we never know.
who wants to predict?
i think i will just let things take their course.
with a little help with technique, history, and
experience.
get this thing going, let it candle over night.
then hit it hard in the morning, about 4:30 a.m.
hell, can't break with tradition, or luck.
but, good skill always wins.
i loved telling that to my swimmers and divers before
a big meet....`hey, good skill guys, if you need luck to
win, well, you may not have it today...so depend on skill.
and it worked most of the time.
mel/mn
have to hit that reduction early
have to watch it close...lots of sheknows...and
bright reds.....make me twitch.
sending pots off to hog chain mary, to fire
during the passover to a new year.
great fun.

Now I know how men feel about asking directions. I have a 16 cubic foot
Olsen. I load two tiers, each with two new 12X24 acme marle hi alumina
shelves, and six advancers. I fire to cone10 ish in reduction. Problem:
The bottoms of my pots stick to the advancer shelves, as also do the kiln
posts. I work only in porcelain. Pete Pinell gave out a kiln wash formular
of alumina hydrate, e.p.k. and something else. Is that suitable for
advancers? I notice they are developing a slightly raised surface. Does
any one have Pete's formular or another good one? Also, and even more
worrysome, is a question of weight. I make a lot of dinnerware. The hi
alumina shelves at the bottom each carry 3 plates and 2 plate setters, 3
small plates,2small setters. this gives me just 12 each. I would like to
fire more plates on setters,but am afraid the wieght will make my shelves
will sag. One advancer has a slight bow as it is. 12 advancers cost about
$1440, so I'm not wildly enthusiastic about replacing them. Has anyone
experience with this? I do fire at least 2 more shelves with 2 plates and
one setter each. I use hi alumina setters that one attaches feet to, but
they are too big to place side by side on the advancers unless the feet hang
over. I place the setters kitty corner to each other. I seem to have
several questions here, but any help on any question would be great. Thanks

Can't tell you Pete's formula but it is probably Alumina, Kaolin and
silica unless you're doing soda.
I us a latex wax resist and add a little alumna hydrate to that. I
started doing that when my porcelain lids were fusing shut. The alumina
in the wax resist cured that problem. It would also solve your porcelain
foot problem as well. After the firing the alumina hydrate washes off.
Best wishes,
Marcia

Rikki,
I'd think that if there wasn't enough heat work to melt cone 11, then=
a
good shelf shouldn't move. I've gone hotter than that and my cheap clay
shelves are still Kansas flat.
As far as weight, 15 coffee cups would weigh about 20 pounds, and tha=
t
certainly shouldn't warp a shelf! I don't know how much the advancers sho=
uld
hold, but you could call the manufacturer or distributor.

Rikki,
I wouldn't worry about the weight of dinnerware and setters. I would
guess the wash recipe is Alumina, flint and epk, equal parts by weight. Are
you using three posts? that can really help prevent warping. Put one post in
the center of a long edge, and one post at each corner of the opposite egde.

Hi Stephen, Thank you for replying. I try to always be careful about how I
load. I always allign my posts [3] exactly above each other. What has
worried me is that just one of my advancers sagged a little. I think it was
the first firing after itc'ing the entire kiln. Maybe the heat [at about
cone 10] flashed to a higher temperature briefly. There is no evidence of
that, the 11 cone didn't flatten. Maybe it is just a minor defect in the
shelf. If my plates weigh about 3lbs etc I think I may have about 20 lbs
per shelf. Do you have any idea how much weight those can carry,
cumulatively? I love using them after years of old mullite back breakers.
Thanks again, Rikki in Berkeley where the sun is out, finally.

Hi Lee-
Just a quick note to say thanks for making such great posts to
Clayart. It is a pleasure to see images of your kiln being loaded;
best of luck with the hiduski. How have the Yohen pots been turning
out? Are you still putting some charcoal in the flue channel?
Have a great firing!!!!
