Abstract

Ceramic flatware handles of hard porcelain, aluminum oxide, silicon carbide or titanium oxide, with a center bore for receiving the tang, wherein the surface of the flatware handle is provided with a press-molded relief pattern. Flatware handles of this type are obtained by mixing the ceramic raw materials with a thermoplastic plasticizing agent and shaping them into blanks at 90.degree. to 150.degree. C. The blanks are then given their surface profile by means of a press molding device and thereafter fired. Such a process is particularly suitable for oval flatware handles and handles having a center bore which is to be equipped with ceramic screw threads.
