Abstract: At least one cooling zone and a subsequent homogenization zone are installed between the inlet and the outlet of a forehearth for conditioning and homogenizing a stream of colored glass. The glass temperature in the forehearth is reduced from the inlet temperature T1 to an outlet temperature T2. In order to increase the cooling effect while simultaneously homogenizing the glass temperature at a throughput of at least 70 tons per day, a raised area is installed in the bottom along the length of the cooling zones to set a maximum bath depth Dmax of 120 mm. Furthermore, the cooling capacity is such that the temperature 20 mm above the bottom is reduced by at least 40.degree. C. in the cooling zone. In the apparatus used, the raised area above the bottom covers the complete length of the cooling zones K. The maximum depth Dmax of the glass bath is 120 mm above the raised area and in the homogenization zone the channel is at least 30 mm deeper.

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 at least one homogenizing zone for the glass temperature is connected. In the working end or the distribution channel the temperature is reduced from the entry temperature T1 to an outlet temperature T2. In order to achieve the necessary conditioning and homogenization, even at high throughputs, the glass stream in the at least one cooling zone of the working end or distribution channel 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.

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.
