plugging kiln

Hello to all.
A friend of mine has a slight dispute with her
co-worker, and I promised I'd ask this on clayart for
her.

My question is: Should a person plug the top peep of
the electric kiln when firing? Should this be done
during bisque and/or glaze firing? If it should be
un-plugged (open peep), why?

Thanks for responding!!!

Leaving the top plug out will extend the life of the
Kiln Sitter tube. Corrosive fumes will leave the kiln
through the peephole instead of through the porcelain
tube.

If you use a kiln vent, leave the peepholes plugged.

Leave the top peephole unplugged for extra
oxygenation. However, if you experience problems from
cool air drafts (such as crazed spot), you should plug
the top peephole.

Never heard of not having it plugged. Except for keep the door cracked in
the beginning of a bisque to allow water vapors to escape and to bring temp
up slower. Seems like any time after that is a waste of energy. Sort of
like turning your furnace on when you have your windows open!

Elise,
I have a Skutt KM1027. The manual specifically states that the top peep
should remain unplugged during the bisque firing. Not sure why, but I do
what the manual says. I suspect it has something to do with air
circulation, though. Also, I use the envirovent. As for glaze firing, I
haven't used this kiln for it yet, so I don't know what what manufacturer
recommends.

Elise,

If you are using a kiln sitter, you should leave the top peep hole open
(according to the manual that came with my small kiln) during the entire
firing. The reason for this is to allow gasses to escape which would
otherwise escape through the kiln sitter aperture and cause this device to
become corroded and not function properly.

I have a Skutt 1227-3 and the envirovent, I keep all "peeps" plugged during
firing. AFTER candleing with the vent OFF and top cracked open and top peep
open, THEN turn the vent on, close lid and plug everything except the tiny
holes on top, before continuing the firing.
The openings during candling is only to allow any moisture to escape up and
out and not through the vent, which might cause premature rusting of the fan
assembly.

Elise, The question whether or not to plug all the peep holes appeared on
clayart some time ago. I closed all the peep holes of my electric Skutt
kiln and found that the porcelain (?) plug on the top peep hole would pop
out sometime during a glaze firing and shatter on the cement floor. Since I
do not like the idea of leaving a peep hole unplugged I fashioned a plug
out of a fireclay brick, drilled a hole through the center about the
diameter of a pencil, and have had no further problems. Mia in sunny ABQ

Typically during the bisque fire it's a good idea to leave to top peep out
the expedite the escape of water gas and other volatiles.. Although I fire
exclusively gas I will normally not close the top peep until I get in the
400 celsius range..

-------------------
I was told that the top peep hole of an electric kiln should be left open to
prevent deterioration of the kiln sitter. If the peep hole is closed the
effluent will escape through the kiln sitter and cause it to wear out more
quickly.

However, there are systems out there designed to remove
"gases" from the
kiln and if one of these is in place you may actually be
expected to leave
the plug in. the venting system that draws air through
small holes in the
lid and floor of lthe kiln and vents them outside of your
kiln room comes
to mind.
