Method for the forming of glass or glass ceramics

A process for forming glass or glass ceramics is disclosed, wherein a glass ceramics form ( 12 ) is made from a starting glass by molding, which is transformed by a heat treatment into a keatite glass ceramic comprising predominantly keatite mixed crystals. With such a keatite glass ceramics form (...

description A process for forming glass or glass ceramics is disclosed, wherein a glass ceramics form ( 12 ) is made from a starting glass by molding, which is transformed by a heat treatment into a keatite glass ceramic comprising predominantly keatite mixed crystals. With such a keatite glass ceramics form ( 12 ) formed bodies can be prepared from blank parts by sagging under gravity force at a temperature above the glass transition temperature of the blank part ( 14 ).
