ABSTRACT:
The invention comprises a method for the continuous opalization of glass, wherein an opalescent agent is added to the molten glass in the forehearth situated between a glass furnace and the automatic forming machine, followed by adjustment of the glass temperature so that the opalescence takes place either before the automatic machine or at the latest, during the annealing which is carried out after the automatic machine.
