Charcoal Kiln
The charcoal kiln is a west cost brand updraft kiln that I modified to replicate the firebox of the Anagama wood kiln. 
There are air intakes in the bottom of the kiln and two forced air burners coming in through the back. The work is tumble stacked using wadding and seashells between the two bag walls on either side of the kiln. I fast fire the work up to about 2000 degrees. I then dump about one hundred pounds of mashed up mesquite charcoal onto the pottery using an angle iron through two ports on the door of the kiln. This is done again later in the firing. After several hours the kiln is shut down and unloaded the following day. A large portion of the work cracks and warps under the intense stress of the firing. The pots that survive the firing come out with heavy ash drips and flashing marks. 
By stacking a lot of the work upside down, it can still be used functionally. The majority of the work that I put into this kilns are large wall hangings and tea bowls.
