up to 2300 plus

You havn't asked yet, but OH YES, it was on your mind. 'What's all this talk about kilns, computers, microwave ovens?'
The kiln I use most often, to about 2200 degrees F, which is what, about 1000 c? is on the right. The large blue box on the right is the firing control, you can just see the digital readout and number pad on the top. Yep, just like a microwave, roughly: key in time, temp, hit start. It has an automatic program you can use, or alter as you prefer, and it goes slooooow at first, then fast then faster, and sloooow at the end, and I program two extras: at the start I XXXXXXXX secret and at the end I also XXXXXXXXX secret. The second bit, at the end, promotes crystal development, and each of my glazes has a lot of XXXXXXXXXX secret ingredient one, two, and three, to make crystals. Crystals, to the layperson, are speckles, in this case. If you XXXXXXXX for 3 hours, it would make huge crystals, but I don't do that.
Anyway, industrial blower on top with a counterbalance on top, to raise and lower. Big duct out the window to remove water vapor, sulphur dioxide and carbon something oxide, out of the house.
The 2 little kilns on the right are also electric kilns, and I don't use them often, unless I have to repair the big guy. I have torn the big kiln apart a few times: the more fancy features, the more that can break down, sigh.....like the thermocouple, twice replaced, 5 of the six elements, and most of the wiring inside.

Neato, Gary. So, you gas your neighbours when you're firing?

Oh, 2200F = 1204.44444C ... So sayeth Google.

Well, there isn't that much gas, but it can't stay inside.
Nice calculation. Good work. Is it 40 below where f and c matchup?

That's the spot. But, really. If it's that cold out, who cares what scale you're looking at? ;-)

Yeah, and don't lick the flag pole, no matter who dares you.

Poor guy probably can't eat anything but oatmeal.

He's had almost 30 years to recover from the injury ... The last I checked, Pete can walk and chew gum at the same time, too ... :-D

You know, if you built a scrubber of sorts and or constructed a simple boiler conversion, you could heat your house with that thing when it is in use.

i was just thinking that same thing.

Master Dib, you better believe that sucker warms up the house. The vent or blower does draw off some air and heat obviously, but we don't need to use much household heat on firing days. We have also calculated that power used per firing is only about 3-4 bucks, and if it holds hundreds of dollars worth of pots.....

Gordo, maybe he now has a calloused tongue and can eat chili peppers with no fear?
