Thanks for that info Dave, I bagged and got rid of the asbestos last
night. It appears that the big difference between mine and the new kilns
is that the electrical box's on them have an air gap of about 1/2 inch
between the brick and the box, "mine would have been screwed directly to
the side without an air gap. One thing that I found out at Seattle
pottery was that most, if not all, of the new kilns have all the heating
coils on one circuit, like they all come on at the same time. Mine is
set up as 3 separate circuits originally but since I have to wire the
whole thing anyway I will hook all the heaters to one circuit. That is
unless the people on this NG say it's better one way or the other.
Thanks for the help and please keep it coming, Bri

Hi Brian,

Your bargain kiln sounds very old, but should be OK. There are still lots of
kilns that age in regular use.

Toss the asbestos covered wire away. For high temperature connections, you
cannot use copper wire - the wire must be multi stranded nickel alloy.
There is a high temperature silicone insulated wire available to use on kiln
wiring, with or without braided sheath, which has the necessary multistrand
wiring. It is available from most kiln manufacturers, or you might get some
from a specialist wire store.

If the elements are new, there should be no problem fitting them to the
kiln, you can stretch or bend the wire without problems, until it is fired.
Then it becomes very brittle, and can't be moved unless it is red hot.

Hello All:

I am very new to this stuff and could use some pointers, but last week I
came across a great deal on a kiln and wheel. The kiln has never been
assembled, it is about 30 years old, it was sold by Westby Ceramic
supply and is 4 rows of 8 bricks each, 3 rows have heating elements and
one row is a spacer row. I don't know where the spacer row is supposed
to be located in the stack, or if it even maters where it is placed. I
had to lay out bricks and trace the ring on them and cut the bricks to
shape for the lid and base of the thing. It's all held together with
bands, 2 for each ring and one for the lid and one for the base. Now I
need to coat the lid and base with this mortar stuff that is in the kit
and install the coils and wiring. The wiring is asbestos covered so I
don't want to mess with it. What do kilns use now a days for wire that
will hold up to the heat? Does anyone have info or experience with one
of these kilns?
Also the wheel that I got is called a spinning tiger. It is missing the
rubber drive thing on the motor shaft so I ordered one from Creative
supply, it seemed awfully expensive for a piece of rubber, It doubled my
cost for the whole outfit!, I got the kiln, Wheel and a box of clay for
$25.
Anyhow, please post any helpful comments that you may have, Thanks,
Brian
