Abstract

The present invention provides a component, particularly a plunger or stirrer, for use in the manufacture of glass articles such as bottles, which component comprises a ceramic tip, an elongate, hollow metal support member, fixing means for fixing the tip to the support member, and cooling means for causing or allowing a cooling fluid to flow interiorly of the support member for cooling the same. Typically the tip will be manufactured from a suitable glass contact refractory material and can be accurately dimensioned and finished.
