Hi Tony - you can see what Steven Hill has done in electric and he has just
started. - it's really fabulous - They are fired to about cone 7 with some
slow cooling.

Without starting the debate of kiln royalty- wood, oil, natural gas,
propane, electric I have a question of you. My aunt and uncle fired
their lead glazed e-ware in a gas kiln during the 50's and early 60's
then switched to electric. The early gas fired glazes are
faaaaaaaaaaaaaar superior in depth and quality.
At home here I'm looking at a temoku teapot set that Sheila fired back
near the flue and it oxidized producing a beautiful oli spot temmie.
With your oxidation gas firing and testing of the high iron glazes for
oil spot and hare's fur did you or anyone try them in an electric kiln
with success. Do they hold up in quality to your gas fired ones???
I'm trying to leave this one glaze to a kiln zone and thought maybe a
small electric for temmies might do the job but I want the depth that
Imagining comes from the solid fuel. What's your take on my
suspicions.
cheers,
Tony

Hey Tony,
I believe the most important issue in answering your question is cooling.
Most gas fired kilns are much better insulated than most electric kilns (to=
p
loading, sectional) that one would find in many potter's studios. A well
insulated kiln will cool slowly. The exception with electric kilns are the
newer front loading electrics, with much better insulation, that might matc=
h
the slow natural cooling of gas fired kilns.
Slow controlled cooling allows for crystal formation that helps to provide
the depth in the glaze. Programmable electrics allow us to cool as slow as
we wish, in fact control the entire firing cycle.
Understanding the benefits and limitations of gas vs electric kilns is
important if one is attempting to achieve specific results.
If one wants copper reds, a gas fired kiln would seem the most logical way
to go, as reduction is required.
If one wants oil spot, iron reds or crystalline glazes, then I would sugges=
t
the electric kiln would be the way to go, as oxidation is required.
Certainly one could fire in oxidation in a gas fired kiln, if the kiln was
designed well and the person firing the kiln understood how to fire it.
Having said all that, load up pots with those glazes in a programmable
electric kiln, enter a program that matches your firing cycle in the gas
kiln, both heating ramps and cooling ramps. I would expect results to be
similar glaze depth but a "cleaner" look.

Hi Tony,
Glaze "depth" is mainly a matter of controlled and slow cooling and
has little to do with what kind of kiln the glaze was fired in. It
results from tiny crystals forming in the body of the glaze and
crystals take time to grow. Electric fired work can have that quality
if the kiln is fired down at the same rate that a comparable gas fired
kiln cools.
But if you just turn the kiln off and walk away--there won't be any
depth.
Regards,
John

I will be testing Mashiko glazes in electric. The soda kilns
I have been firing reduce too evenly for them to have a place and
turn tenmoku a scuzzy green. Also cone 1 redware in electric. I
fired some terra sigged pots on shells in the test kiln and they look
pretty cool.
