Small single phase kilns that fire slowly are an abomination.  My small kiln, apparently called Mr Edward as it is written in large lettering all over the side, is one of these.  It fired the test glazes to 1240 C so slowly that I had to make three increasingly enraged trips to the studio from my house in Paarl after 5.00 p.m. before I could switch it off.

Approaching cone 7 at 9.00 p.m..  Slow fire de luxe.
