ABSTRACT:
A method of controlling the exit glass temperature and the thermal homogeneity of the glass exiting from a glass forehearth having at least two temperature control zones and having in each temperature control zone at least one temperature regulating means responsive to the difference between a set point signal and an actual value signal for each temperature control zone. The temperature control method includes adjusting the set point signal of each temperature control zone as a function of the temperature of the glass entering the glass forehearth and as a function of the temperature of the glass exiting the glass forehearth.
