Hi,
I'm new to CLAYART, but not new to clay. I will be purchasing a downdraft gas
kiln this Spring and need some input. In the past I've built a downdraft
(many years ago) but this time I'm planning to buy one. Don't want the
problems I encountered in the past. Although I seem to be facing new ones.
Like, which one to buy. I'm in NY, so I'm considering the Bailey. But folks
I speak to tell me that geography should have nothing to do with my decision.
If there's anyone out there with a car kiln, who either loves theirs, or hates
it, can I please hear from you. Also, if you recommend a regular downdraft
that isn't a car kiln, I sure would like to know why? After reading all your
esoteric messages for a couple of days, I'm sorry to ask such basic questions.
However, It is a lot of money, and hopefully will be for a long time. So I
just want to make the best decision I can. Thanks for your input.

When I went from my DIY kiln to a store bought type, I went to everyone I
knen and asked. then I visited all the local kilm\n builders. I ended up
with a local kiln builder who made me the kiln I wanted. I wanted a down
draft. He liked a \n updraft. I told him to make me an updrft\down draft. I
buisqe up and highfire down. The updraft feature allows me to get some
additional top to bottom evenness.

This can be a problem with tall, narrow downdraft
kilns, but is curable! Build a bagwall to deflect
most of the flame upward as soon as it enters the
kiln. Tightening the damper will help if too
much airflow was the problem to start with, (This
is what the brick-in-the-flue tries to do, also)
but that's less likely. Adjusting the bagwall
will have a huge impact on heat distribution in
any downdraft kiln.

I will be firing a small downdraft salt kiln at school this week. I've only
done it a couple of times but this kiln always seems to be hotter on the
bottom (which makes sense to me being that it is a downdraft kiln). My
theory is that the arch is too high-- it's very narrow-- and very hard for
the flame to heat the top, it just shoots across the bottom and out the
chimney. I've placed a brick in the flue to deflect and staggered the
shelves. Any other suggestions on how to get that heat on top without
closing the damper down and getting too much reduction? We will be only
firing to ^6. Thanks for any help you can give.

When you get near a flat ^5, starting reducing with a hard reduction
flame at the top and a soft licking reduction flame athe bottom.-if you
have two peep holes. You might stack the bottom tightly with a 6-9" post
but not too short and then pack the upper part a little more tightly. We
had a kiln that I rebuilt raising the arch for more space.
Good luck.
don't forget a Kiln God.-it never hurts.

Hi!
I have a 15 cubic ft. downdraft kiln which I would like to set up and build a
shed for. I really don't know how to go about this myself and I need some
help.
I want to set the kiln up at my cottage on the edge of Lake Michigan, and I
want to be able to fire at cone 10 (reduction).
Does anyone out there know anyone in the Michigan area who can provide some
assistance in getting me up and started.
Many thanks,
Edie Clark
