ABSTRACT:
A method and apparatus for the production of colored glass includes the steps of diverting a stream of clear molten glass from at least one glass melting furnace through one or more transport channels to a color treatment chamber. Recycled cullet and color additive are added to a charging end of the treatment chamber. The treatment chamber is heated to melt the cullet and further heat the remaining feedstock to form a molten bath of colored glass which is thermally and chemically homogenized in the treatment chamber. Refractory rotary paddle wheels positioned in the transport channels regulate the flow rate and level of the molten glass and provide for selective shut off of individual glass streams. A glass level sensor is located in an outlet channel of the treatment chamber and is electrically coupled to a programmable controller to selectively regulate the rotational speed of the paddle wheels responsive to glass level fluctuations to maintain a controlled gob weight of colored glass supplied to the glass forming machine.
