Blaauw kiln at the Potter's in Residence program at Medalta Historic site in Medicine Hat, Alberta. This type of kiln has an automatic controller that controls the firing schedule and atmosphere inside the kiln. These kilns are expensive, but bring the same degree of precision and convenience to reduction firing that electric kiln users have been enjoying for some time.
A method of firing stoneware where the kiln air intakes and burners are set to restrict or eliminate oxygen in the kiln such that metallic oxides convert to their reduced metallic state.
