Forehearths that create a substantially homogeneous temperature to molten glass forming materials across the end position are provided. A gas cavity, a weir, a refractory block, or a heating element in the forehearth may be utilized to reduce a temperature gradient of molten glass forming materials across the end position. Reducing the temperature difference of the molten glass forming material across the end position permits for improved chemical and physical properties of the glass fibers and the end products formed from the glass fibers. In addition, a reduction in the temperature gradient across the end position produces a more homogenous glass fiber and glass product. Further, a reduction in the shear break rate occurs when the molten glass forming material has a temperature that is substantially the same across the end position, which results in a reduction in the breakage of glass fibers and an increase in manufacturing efficiency.

Apparatuses for controlling the temperature of glass forming materials in forehearths

A filament forming apparatus and cooling apparatus for and method of inducing a uniform air flow between a filament forming area beneath a bushing and the cooling apparatus are disclosed. The cooling apparatus includes an air housing extending beneath the bushing. The air housing has a top wall and side walls defining an air chamber therebetween.
