Abstract
A shield for protecting a pyrometric cone of the kind conventionally used in the control of ceramic firing kilns comprises an annular or arcuate member open at both ends and provided with means for mounting it within the cone in a position to protect the kiln against dislodgement or other adverse consequences due to the tipping or falling of greenware within the kiln.
