Kiln Schematic
The general scheme of the kiln is shown in the sketch to the right. Its a very cheap and quickly built design. Pleat refers to pleating made with alumina-silicate kiln blanket material.
Kiln Elements
Kiln elements will require no coiling. Due to the size we can lay the wire in linearly in a fashion depicted by the photo on the left.
Why old kiln method was discarded
The second photo on the right in included to illustrate by firebrick is impractical. At 140 brinks it would be a good dose of money and very hard to deal with. Cost ~500 USD would be high. In the end due to varying thickness of the mold bottom we would be required to cover it with sand also to do mold leveling. Therefore the brick idea was discarded in favor of using a "toilet paper" roll of fiber blank. This works not only on the bottom but on the lid of the kiln also. The only other option for the lid would be fiber board. That could run in the thousands just to get enough insulation thickness.
