Abstract: A system for and method of analyzing a cullet stream prior to batch formulation in glass manufacturing. Cullet is fed onto a conveyor where a real-time composition analysis is performed. Contaminants are optionally removed, and a determination is made as to whether the cullet batch color is consistent with a predetermined tolerance threshold. If necessary, the glass batch formulation is modified in view of the cullet analysis. Virgin raw materials requirements of the modified glass batch formulation may then be communicated to the batch controller before sending batch ingredients to the mixing stage and completing the overall glass manufacturing process.
