The base of the kiln starts with 2 layers of cinder blocks.
Next, the floor is 3 layers thick; hardbrick wherever there will be weight, and softbrick everywhere else. The walls are started 2 layers (9 inches thick).
The walls are mostly completed and the steel is cut and welded into place.
The skew-bricks are placed on top of the side walls and the arch form is put in place. the arch form is made of 3 pieces clamped together and shimmed up slightly to make it easier to remove. There are 3 pieces of angle iron welded to each side to hold the skews in place.
Laying the arch. 2 layers of arch bricks and straights make up the arch.
A third layer of recycled bricks is layed on top for added insulation.
The center of the arch form is unclamped and removed.
The sides of the arch form are removed.
