electric kiln outdoors and gas oxidation firing question

I have two questions. How detrimental is it to have an electric kiln
outdoors (in a high humidity climate) if it is under a shed.


How does Cone 6 firing in electric kiln compare to cone 6 oxidation firing
in gas kiln? Are the results similar??

Thanks a lot.

Claudia,

You don't say where you are living but my personal opinion is that it
shortens the life of your equipment. My kilns are for all intent outdoors.
I have two walls, a roof and the other two sides are bug screens. In other
words the kilns are exposed to the humidity and salt air. It could be the
salt air that is ageing everything.

My Skutt Electric which I purchased (new) here 4 years ago is beginning to
show its age. The stainless casing is rusting and the enviro vent is making
funny sounds which means the squirrel cage has probably rusted out and is
about to stop functioning. When I moved here, I shipped a small Skutt that
was over 20 years old but it was used in the lower level of my home and not
subjected to humidity or salt air. The envirovent burned out on it two
years after moving here but then it had seen many many bisque firings.

I don't think humidity really hurts the bricks but I am not an expert in
that area. Everything around here that is metal takes a beating. Humidity
is hard on people and equipment.

i think it's best to keep the kiln outdoors if you can. and if the oxidations are the *same* you'll get the same results in gas or electric.

trick is, getting consitancy with electric is easier then with gas. but not impossible.

see ya

I think maybe keeping electric kilns outdoors is also hard on the electric
connections and the spades of the plug and the outlet too. This may have
been been the cause of our fire which wiped out fifteen years of our lives
and from which it now appears we may never recover. I suggest keeping a
very close eye on the connections in the outlet if it's outdoors or not in
a dry heated environment. (well, keep an eye on that stuff regardless of
it's location.) Watch for corrosion. Check often. Maybe consider doing
away with the plug and outlet and hardwiring the kiln directly into the
breaker box or subpanel.
