Self Support Cone 4

About

Whatever temperature indicator or controller is used to control a firing it is strongly recommended that Orton cones additionally be used since they monitor heat work rather than temperature.

They reliably monitor the effect of heat on the ware load and also the heat balance in various areas of the kiln.

Heat rating oC per hour is the same as No 4 Standard cone
