Abstract
A ceramic interiorly threaded hollow insert for incorporation in a refractory preformed shape such as hot metal runners into which eyelet carrying bolts may be threaded so that the preformed shapes can be handled by mechanical means. The ceramic insert is made of material similar to that of the preformed shape with which it is used. The ceramic insert is bonded in the preformed shape during the drying and baking formation thereof.
