Cones and Rings

Cones to check temperature;rings to check accumulation of ash. Lots of them to spread throughout the big kiln.Rings:brown Tzemach clay [3 pinches on top] and K117 [5 pinches],cones 8,9&10 [for the hot front,we made some cone-pads with 8,9,10,11&12,the last bending at 1320 degrees,which should be quite hot enough.]
