A big soft candle flame wrapped with heavy hard bricks
It was my simple Anagama concept but it was not easy in practice.
Layer by layer, I had to place the ultra heavy bricks. 2 front air-ducts and another 2 spy-holes were made. Chipping the heavy gricks into the shape I wanted was not an easy job. My kiln site has no electricity and I have to do most of my work by a pair of hands. I also must wear clear goggles when I chipped and shaped the bricks with masonry tools.
I am careful about The front wall which must be curved and has no blind corners where often cool air lingers during the firing.
Anagama ‘Moby’ has a fire-mouth (which devided into upper and lower in front) but has no ash-pit. I have never designed a proper firebox nor dampers for my Anagama.
I still have to work on a few details like a chimney, an interior wall (flues) and a mortar cover over bricks for insulation. Yet I can safely say that the hardest part of Anagama building was over.
I did not want to use any modern kiln materials (soft white bricks & kiln blanket), so ‘Moby’ was mainly build with bricks and mortar (fireclay and sand).
