My new “Tin Can” Kiln

After many years of designing and custom building kilns I wanted to create a super low tech and totally inexpensive way to fire my Chawan, Yunomi and Guinomi and other Teaware.

I located a small old Duncan electric kiln that I stripped of everything and preserved only the shell. Next I drilled 2 burner ports near the bottom just above the level of the floor. I then cut a flue vent in the lid of the kiln approx. 1.25 times larger than the combined area of the burner ports. I use an old broken kiln shelf as a damper to facilitate reduction. I drilled a small hole through the wall of the kiln to insert a K-Type thermocouple that I use to estimate when to start reduction. I start my reduction at a relatively low temp. @1560F, this start point is necessary for the carbon trap glazes that I use.

I fire using two 5 gallon propane tanks with two venture type burners running of a 12 WC regulator. I fire to ∆10 (2345F) in less than 6.75 hours on 4.9 gallons of fuel.

Take a look at the short video below to see and hear this kiln as it approaches 2300F…Let me know what you think and if you should have any questions.

Thanks

    Hello Michael:
    You mention you use two burners. Your video only shows the one, I imagine the other is directly opposite. Do you use any sort of baffle/bagwall arrangement to direct the flame?
    Nice work, your glaze combos are amazing.
    Regards Dick

    Hi Michael – thank you for posting this. I have two students who are interested in firing in this manner. We have an old kiln ready to go but I am trying to figure out the burner system. I have a Ward MR-100 Raku burner system. Do you think adding a second one would give the necessary power to reach Cone 10? Thanks so much!

    Hi, I think I sent a reply to the wrong spot. How big a shell do you think would work for this set up? sometimes easier to find bigger, like 24X27. I’m inspired. Thanks.
