Craigslist, not unlike my cats, can cough up some remarkable stuff from time
to time.
In this case, it's an old .85 cu.ft., 110v, Evenheat 1210 "china painting
kiln" being given away by a grand-daughter clearing up her deceased grand
mother's estate. From looking online I see that newest versions of same
sport a kilnsitter. Not this one. The venerable model I just obtained via
Craigslist, free for the investing of a little sweat equity lugging it out
of a basement, just has three switches on it's side and nothing that looks
like a kilnsitter. There is a large peephole (maybe 1.5 or 2 inches in
diameter) with a plug made of firebrick.
So... back before computerized controllers and kilnsitters (somebody on this
list *must* remember back that far, right??? I know, it's a stretch and God
*was* still in diapers, but... ), I'm guessing the trick was to place cones
within eyeshot of peepholes even on small electric kilns and then keep an
eye on 'em.
I'm wondering if someone can give an educated estimate for a fireing
schedule to reach ^04 with a small kiln like this one? I'm guessing a few
hours, but using Scutt 818's with a kilnsitter or a controller (w/ varying
degrees of "set'n'forget" convenience) has meant I've not internalized the
time for reaching temps with such kilns. The Evenheat 1210 is so much
smaller that I really don't have much of a base for guestimating a fireing
schedule.
Thanks and Peace!

Hi Jeremy,
Besides the cones behind the peepholes, you can keep an eye on the color
in the kiln. A dull red glow will mean you are moving up in temp, but
the kiln will need to look orange before you have to start keeping a
really close eye on the cones. Watch the color in your Scutt as you
fire and this will give you an idea of the color to watch for in the
little one. Analog pyrometers can sometimes be found attached to old
kilns or on e-bay for around $75 bucks.
Calibrate it with your skutt and then use it on the little evenheat.
Think of Raku. I fire raku by color of the kiln and melt of the glaze,
no cones needed.

Dear Jeremy McLeod,=20
If this is a genuine china painters kiln you may be stretching the =
boundary of credibility by attempting Cone 04. Much of the work done in =
that genre was fired in the 600-700 deg C range and the elements might =
be Nichrome, not Kanthal.
There may be a hole for a pyrometer.
But it is worth playing with.
If the manufacturer is still in business why not ask them.
Best regards,Ivor Lewis.

You can even buy a new digital hand-held pyrometer for that
price, complete with K-type thermocouple.

A .85 cubic foot firebrick kiln will fire very slowly on 120
volts and probably will not fire hotter than china painting
temperatures, as Ivor said. But if it still fires, it is a
real find. You can use it for copper enameling.

For about $75? An honest-to-gosh pyrometer that goes to 1300 C?
Where??? I've been looking, but finding only much higher prices than
that!

We carry a digital pyrometer for $75, but it reaches only
1999F / 1093C.
