I've heard on old china doll type kilns that the brick itself does not survive past a certain rating? Have you tried adding a layer of fiber as insulation?

We have checked the plug and circuit feeding the outlet. All appear to be functioning properly. At this point I don't know what else to try. Any suggestions would be welcome. Thanks,

I had a crucible oval for ages and dealt with Seattle Pottery for 30
years. Good folks.
As for the Thermo Lite test kiln, I would suggest insulating it. You
could do a "Linda Blossom" and take the jacket off, put a layer of
fiber and replace the jacket. I'd spray the lid inside with ITC and
cover the lid when firning with an inch more fiber. I have a little
crucible test kiln that goes to ^7 on 110 in about 5 hours.

Judy, your kiln is about the size of a Paragon X-14J china
painting kiln. It, too, is low fire only.
I don't think you will get it to cone 6 on 120 volts. You
could convert it to 240 volts, but it may be less expensive
and time consuming to sell it and find a used test kiln.
A 6"-cube 120 volt kiln will easily reach cone 6. You can
use them for anything--silver jewelry, stoneware testing,
copper enameling, glass fusing, etc.
Sincerely,
Arnold Howard

He also had a very old test kiln that he 'threw in' for
$100. Although it works great for my bisque and low fire
tests, it does not go to cone 6.
Since the original maximum temperature on the label on the
outside of the kiln says "max. temp: 2000 F", should I
assume it will never go higher than that, even though I have
put new elements in it?
