Kiln Firing - Digitalfire

Three factors made it possible: 1) The low firing temperature. 2) Even slower firing speed (24 hours instead of 12 hours to ramp). 3) Elimination of the direct radiant heat. This clever potter fires using only the elements in the bottom one/third of the kiln (the top 2/3 elements never go on) and puts the rings only in the top 2/3 of the kiln.
