fast fire kilns

steve graber on fri 17 mar 06


i used to have a kiln that was a fast fire kiln. i could do 2 cone ten's a day. it was a dinkensen kiln, about as big as a coke machine. i got the old kiln free, and refurbished it with cloth. it was a hard brick before i added cloth.

while i got great pieces from the kiln, it was too small functionally to hold much besides mugs & thin vases. large bowls simply did not fit. medium bowls could only stack a few to the overall kiln - didn't seem smart from an overall load point of view.

i considered the affects to be like a *cone 10 raku* where the glaze hit solution, but froze there quickly & never had time to use that solution period to move around & soften or blend the colors. i got vapour deposit reactions which seemed to be a local pot throwing off fumes that landed on neighbor pots & froze there quickly. i got matt. slower fire kilns got more satin from identical glazes.

~ i liked the kiln, got lots of product out, and can see fun times with a fast fire kiln.

see ya

My woodkiln is the only kiln I have and I bisque in it. Because both
fireboxes have their entry at the same end of the warechamber, I
think it is easier to bisque with than the Olsen.

It is a combination of the Olsen and the desgin of Mick Casson's
first chamber of his woodkiln.

I glaze fire for 17 hours (can get cone 10 in 5, but looks like
gasfired if you fire that short) and it uses about 400kgs of wood for
a glaze firing.

I've been reading and lurking for a while now and I figure it's about
time to introduce myself--Linda White. I did production pottery about
20 years ago and am now getting back into clay--and having a lot of
fun. My question is--has anyone ever used a fast fire kiln like
Frederick Olsen talks about in his kiln book? Is it true that you can
fire one in four or five hours? Any info would be greatly appreciated.

This is anecdotal at best, but I talked to a potter showing in the
market in Portland last year who used one. He doesn't have
electricity at his homestead (southern WA) at all. I asked him the
exact same question and he comfirmed it's true. Moreover he claimed
he fires it on only a half cord of wood. That I found hard to
believe. He even uses it for bisque ... wood fired.

Hi Linda,
I built a fast-fire kiln. It fires to cone 10-11 in 4-6 hours. We also
use about a half a cord of wood.

Hi Linda,

I fire a kiln that is a couple generations evolved from the
Olsen. Both fireboxes are in front, so there isn't so much running
around. You can see plans and photos of my building here:
