It has been awhile since I have posted due to COVID 19's affect on firings and my schedule. I have made some progress on the kiln(s). The small down-draft will be constructed first and the tunnel finished afterwards. In the meantime I have purchased brick to complete the down-draft. Also, I have converted an old electric kiln to a conversion kiln...what I am calling "Chokkuragama", which means "small kiln". It is close to being ready to fire for the first time. Here are some images taken before the winter set in.
