During this past week 16-22 September 2019 I have been building a new kiln based on a catenary arch design with the help of Gyan Daniel Wall.
The kiln is constructed with firebricks on the hot face backed up by commons and insulating bricks. The arch is double brick construction with back-up fibre insulation, a covering of chicken wire before an adobe ‘cob’ style mud covering.
A fire grate has been installed so as to keep the hardwood suspended while burning.
My thoughts behind this kiln is that I wish to obtain soft quite glazed surfaces from the back of the kiln while those on the hotface will be subjected to direct flame and ash. I am anticipating on firing for 30+ hours depending on stack and wood.
