About This Video:
A Phoenix kiln is a type of downdraft kiln where the firebox is below the ware chamber. It was developed in America in the 1970’s by George Wright and gets it’s name from the Phoenix workshops. It is classified as a downdraft kiln because the flames go up into the ware chamber and then down to the exit flue of the ware chambers before going up a chimney. I built one from mud to learn about how it works and to see how hot it gets.
The mud I used for the kiln is white clay from a flood area and it less than ideal for making pottery.
I tested it and it worked ok but I knocked out the exit flue wall to make it behave more like a cross draft kiln before firing the pots. The kiln worked well in firing pottery despite the poor quality clay which cracked easily. If run for longer it probably would have reached higher temperatures.
About Primitive Technology:
Primitive technology is a hobby where you build things in the wild completely from scratch using no modern tools or materials. These are the strict rules: If you want a fire, use a fire stick – An axe, pick up a stone and shape it – A hut, build one from trees, mud, rocks etc. The challenge is seeing how far you can go without utilizing modern technology. I do not live in the wild, but enjoy building shelter, tools, and more, only utilizing natural materials.
