Abstract

A continuously flowing glass stream is conditioned and homogenized along a conditioning stretch, which extends from an entry side to at least one extraction point, and at the beginning of which there is a cooling zone, to which a homogenizing zone for the glass temperature is connected. This method is preferentially used for the manufacture of molded glass articles, such as containers and pressed articles. In order to achieve the necessary conditioning and homogenization, even at high throughputs, the glass stream in the cooling zone has a cross section with a depth/width ratio D/W of a maximum 0.6 or 0.5, or 0.4, or 0.3, or 0.2, whereby the maximum depth Dmax amounts to PA1 a) 300 or 250 or 200 mm when the cooling zone is situated in a working end or in a distribution channel PA1 b) 150 or 120 or 100 mm when the cooling zone is situated in a feeder or in a forehearth and, at least 30, or 40 or 50% of that amount of energy which corresponds to the necessary temperature reduction is removed from the glass bath per meter of flow path at the beginning of the cooling zone.
