ABSTRACT:
Temperature conditioning of molten glass flowing from a melter to a glassware-forming machine is described. In addition to the attempt at conditioning the molten glass in the forehearth in the usual manner, in accordance with this invention, distribution channels leading from the throat of the molten glass supply to the forehearth are provided with conditioning apparatus. Most particularly, the conditioning apparatus is such that the conditioning temperatures at the opposite sides of the distribution channel may be varied. For example, at one side the interior of the distribution channel may be being heated while the opposite side is being cooled. It is also possible to heat one side to a greater degree than the other while heating both sides. Most particular, the burner construction is such that the burners may be utilized either to heat the interior of the distribution channel or to cool the same. Combustion supporting air is delivered to the burners from a separate source and, when the burner is not being utilized for heating purposes, the same air may be utilized for cooling purposes.
