摘要
Stirring of glass of high optical quality is effected by initiating forming of the glass, such as by the float process, at relatively high temperatures immediately after the glass has been stirred. Preferably, during and/or following the stirring operation contact between the molten glass and ceramic refractories is minimized. This is preferably accomplished by providing a layer of molten metal (e.g., tin) on the bottom of the stirring chamber.
