Hello,
I just bought a skutt model 818 electric automatic kiln-new, and I was
wondering if anyone out there has fired one, and has any suggestions on
using it. I plan on doing cone 10 firing in it. I just purchased some
celadon and oatmeal glazes along with Rhodes black and Shaners blue,
these are all reduction glazes--even though I told him I have an
e-kiln...hmm....has anyone used reduction glazes in oxidation and if so,
what will these colours look like compared to reduced firing? (you
could say that I am new at this) I have only fired things in a gas kiln
and have no experience with the other types of firings...help!

Hi everyone,
I need some help and support here. I wish to rent a room (15' x 20') on the
ground floor of a 34 storeys condominium block where I live to start a
ceramics activity. I have a new property manager, Mr. Gnana who thinks or is
concerned with the electric kiln.
I got feedback from his staff that he is concerned with the electric kiln
exploding, or accidently catch fire...etc thus making it a dangerous thing
to have at the condominium. I have tried to explain and even shown him
articles on how the kiln works.
But I am still not getting a favorable reply to getting this place rented
out to me though many of the residents I know are keen to learn ceramics.
I am asking for some support here - if members of CLayart, kiln builders,
potters, whoever who have a kiln in their homes, condominium, ...etc, please
write a short note about your experience with an electric kiln. how safe it
is and not troublesome, dangerous or hazardous or if it ever exploded and
the damaged caused.
I will collect all your support mail and show them to Mr. Gnana very hopeful
that he might change his mind about renting the place to me.
Thank you all...
Best Regards,
Jan

All you need to do is find out if the apartment complex has insurance and if
the kilns are covered. some companys do have coverage and some dont. if they
dont you can see about getting it on your own. as far as safty its only as
safe as the way it is used. it all depends on your fireing habits. my
insurance company conciders my kilns as safe as my wood stove or my elcetric
range.

Dear Jan, I have often operated small,(18X18") electric kilns in rather
confined spaces without incident. If the manufacturers directions are
followed and with the concurrance of local codes,there should be no
difficlty. A minimum of 18" surrounding the kiln is usually felt to be
enough space,although I prefer 36" all around the kiln and 1 minimum of 12"
between the kiln bottom and the floor,which should also be protected by
Sheet Rock or other dense fireproof material.This should be raised an inch
or so above the floor simply for air circulation.
You have not mentioned the most important aspect and that is, a means
of collecting and discharging fumes to the outside air, For a small kiln a
simple discharge fan should be sufficient if the exhaust is not far from an
opening window. For larger kilns more elaborate exhaust fans must be used. Don

Thanks to all who helped us decide to go ahead and get an electric
kiln. I'm running it through the first firing tonight. We've got a
bunch of stuff that's accumulated over the past few weeks that we will
bisque fire in the next few days, if all goes well.
This is probably a dumb question. How do you decide to what temp (cone)
to bisque fire pieces? Most of our work, thusfar, are various clay
pieces pressed from molds of slab built sculptures. The clays are mixed
in many of the pieces, various kinds of clay (porcelin, etc., mostly
high fire clay). We are planning to spray paint some and glaze others.
Some are quite thick so I guess I'll need to bisque fire them very
slowly. I've previously done all my work in a studio where someone else
fired everything. This is new and exciting. I appreciate the help.
Thanks, Greg

Can anyone recommend a cone 10 electric kiln for heavy duty studio use? It
needs to have a good ventilation system and programmable controller. Thanks in

I Am finally getting around to building a studio in my basement. Can
I safely install an electric kiln down there? This kiln would be
going into what I call my slop room area- It's located under my porch
away from the rest of the basement near a window where it can easily
be vented-- on a cement floor with fireboard around it. I guess I'm
wondering if anyone else out there has their electric kiln in their
basement and if you do can you give me some tips what you did to make
it as safe as possible.
Laurie Kneppel on thu 8 jul 04
Hi Patrice,
As long as the kiln is safely ventilated so fumes can't get drawn into
your living area from either the basement or just wafting up from the
window vent the only other thing to watch out for is that even a well
ventilated and well insulated kiln still generates a lot of room heat.
So make sure it is in an area where that won't be a problem. My Skutt
KM 1027 is in an attached garage as far from the house as possible. I
have a Bailey vent attached underneath the kiln that does a good job
sucking the fumes outside, but the garage still gets very warm. If I
fire on a summer night the temp the next morning in there will be close
to 90 around the kiln. 80 on the opposite side of the room. Not
dangerously hot or anything, but just not the most comfortable if I was
planning to throw out there the next day. Box fans and opening the big
door take care of it, but in a basement that might not be an option. I
also have a CO detector and smoke alarm in the first room inside the
house from the garage. So far no CO or smoke detected.
A basement studio sounds nice - you don't have to compete with the car
for space! But then when I am working out there the car gets kicked out
onto the driveway.

Hi,
I set up my workshop in my basement a couple of years ago and like you I was=
a bit
concerned about whether it was safe to have the kiln down there. Another pot=
ter had
told me it was a bad idea because of toxic fumes and the potential for fire.=
Others,
however, said that as long as the kiln was installed correctly there shouldn=
't be a
problem. It's been almost two years now since we struggled to get it down th=
e
basement steps=97and all is well.
I made sure to have the electrical outlet installed by a qualified electrici=
an. In my
case it was the type of plug typically used for dryers and I luckily had eno=
ugh room
on the electrical box to add it. My kiln is fitted with an Orton vent which =
sends the
fumes out the window. A couple of times I forgot to put the vent on and ther=
e was a
noticeable chemical odour from the kiln so now I put the vent on before I ev=
en turn
the kiln on and I leave the vent on until I open the kiln after cooling.
I also made sure there is at least a foot of space around the kiln. It is am=
azing how
hot the thing gets! My kiln is in the same room as my washer and dryer and o=
ne day I
did something really dumb. The kiln had been off for a couple of hours after=
reaching
Cone 6 temperature. I was in a hurry (multi-tasking as usual) and took dry l=
aundry
out of the dryer and sat it on top of the kiln while I refilled the dryer wi=
th wet clothes
from the washer. Within less than a minute I noticed the distinct smell of b=
urning
cotton. It took me another second to realize that the laundry on top of the =
kiln was
smoking! Luckily I grabbed it off before flames erupted but I had to throw a=
way a
couple of things that had burn holes. It was a good lesson: I made a strict =
rule for
myself to NEVER put anything on top of the kiln whether it is on or not. My =
brother
(who shares my workshop and loves electrical gadgets) installed an alarm tha=
t goes
off if the temperature above the kiln is greater than 190 degrees F. It's n=
ever gone
off, but just seeing the alarm's little green light blinking gives me some c=
omfort.
Anyway, just thought I'd share my experience. (This is my first message as I=
just
joined the list!). Hope you enjoy having your own pottery workshop.

Simple answer is yes, with some buts.
Need to provide good kiln ventilation - both venting fumes from kiln
and providing adequate air circulation/ventilation around the kiln.

Ron Roy on sun 11 jul 04
Hi Patrice,
Pay special attention to what Ken said - makup air is essential no mater
how you ventilate.
Have a CO detector installed - preferably the type that detects small
amounts of CO - and be sure to have smoke alarms installed and functioning.
Do not use a plug in type connection - have the kiln hard wired and fused
properly with a shut off at the fuse box - and always shut it off there
when the firing is finished.
Never assume any kind of automatic shut off is fail proof - don't leave
your kiln alone until the firing is over.

I have an opportunity to buy an 8 year old programmable Skutt 1027
electric kiln that has been stored in an unfinished basement since it
was new in 2000. The kiln was never plugged in, never used. I would like
some advice as to what to offer for it and what are the chances there
could be corrosion or other problems with it setting unused for so long
in the basement. There is no power to the kiln so there is no way to
plug it in and test it.
Thanks for any opinions that you could give.

Should not be a problem. I bought a kiln about 4 years ago that was 30
years old and it worked fine.
It was manual though. Did have to replace some switches. You can't tell
about programmable kilns until you crank it up and try it.

Yes, the kiln may have corrosion if the basement is humid. I
suggest opening the switch box and looking at the wiring
with a flashlight. You could also check the elements with an
ohmmeter while the box is open. Check the condition of the
firebricks, especially the lid. In all likelihood the kiln
is in good condition, though, since it has never been fired.
(If it has been fired, the lid will be discolored.)

Yes. You might have received a defective switch. Or, a loose connection
may have damaged your new switch. A loose connection generates enough
heat to ruin new switches and relays within a few firings.
When you removed the old switch, were the wire connections tight?
Push-on terminals should be so tight that they are difficult to remove.
If they come off easily, they are too loose.
Push-on terminals that are discolored should be replaced. The
discoloration indicates heat damage. The oxidation on a discolored
push-on terminal will prevent a good connection. Installing the push-on
terminal might scrape off the oxidation, but the terminal has probably
lost the spring tension. This means that even if you tighten the
terminal with pliers, it will soon loosen again.
When replacing terminals, also replace the wires they are attached to
unless you have a good crimping tool. Crimping a new push-on terminal
with the wrong tool will cause the terminal to burn out.

The normal hum of elements is loudest when the elements are cold. (The
hum is caused by the coils repelling and attracting each other with the
cycling of electricity.) Since the hum from your kiln becomes louder as
the kiln gets hot, it may be due to a switch that is about to fail.
