I just thought I would share this for any potters out there. I'm building a primitive kiln in the backyard strictly out of found materials... from... the backyard! I understand that cinderblocks are certainly not period for construction... but I'm trying to capture the 'process' moreso than the material.
This is a work in progress. The first stage was building a structure with air intake to feed the fire at the bottom, a shelf to hold a wood/charcoal fire just above the open space, another shelf above the fire to place the pottery on, and a tapered top leading to a narrow chimney. As you can see, I'm smearing mud into the brick cracks to begin sealing them (mortar is a big no-no, as it won't allow bricks to expand with heat) but the next step is to bury the kiln entirely (aside from chimney, access walls, and air intake) to insulate it further and make it more pleasing on the eye. Then I'll grow some grass on my kiln and make it look like a nice smokey-chimneyed hobbit house. ;D
Now to get the kick-wheel together so I can start throwing some pots!
