there's a couple in Australia that do the same as you, but they put a raised metal wall around the retort. it's as high or slightly higher than the burn cone. They say that the system draws air from the gap beneath the raised wall. The air rises up and enters the open center of there kiln in like an upside down mushroom cloud ☁ vortex fashion. So it drives the smoke donw into the center and flames comes out the edge

Great informational video. Valuable info

Great video , Michael. T Y

I think this is a great design overall, I just wished the demo was using actual waste wood... It was fueled almost entirely with what I would gladly use in my wood stove indoors to heat my home. I'm hoping we start using these tools to teach people how to make this incredible resource out of truly waste material... Japanese Honeysuckle bush, other invasive branches, dried weedy chaff, diseased prunings... things that would be best served cooked to carbon... Nice, dried, split, stove length wood has a higher purpose to heat a home!

All the wood and products used in this demo are waste product. The cut rectangular boards are remnants from a furniture factory. BlueSky Biochar only uses waste materials in its production.

Good Video. Congratulations.

I didn't realize this before and he very well may have done this on purpose, but he didn't let it burn completely

The idea is to make char, not ash.

Nice video showing the debut of the SoCal Cone Kiln! I hope everyone notices that most of the smoke you see is from the biochar stoves that are not being operated properly! Please, pay attention to your stoves and don't let them smoke like that! More cone kiln lore at my blog, www.greenyourhead.com

Kelpie - do you use the circular arrangement of wood that Josiah does? Does that help the newbies cut down on the smoke with the cone kiln? Or does the open stacking method work better - like the improved field stacking method all you all were working on?

Erin Rasmussen Erin, I do not use the circular arrangement. The cone kiln is not really big enough for the wood to arrange easily in a circle. The wood I use is sized at 1-3" diameter (approx) by 10-24" length. To start it, I make a little teepee fire like I learned in girl scouts. When that has been reduced to a layer of glowing coals about 3" deep, I start adding the sticks in layers, one layer at a time. Each layer is criss-crossed with the layer below. I try to leave a half inch or so between each stick as they are laid down. That reduces the smoke. As each layer begins to char, the next layer is added. Don't add too fast, or stuff on the bottom will begin to cool and won't char all the way through.

Thanks! :-) So a good coal bed is important, and then build up from there... keep the spacing between the sticks so that you've got nice even air flow.

Are these kilns available for sale in the U.S.?
