Methods of creating a batch of recycled glass from mixed color glass cullet. In one embodiment, the method includes receiving at a glass plant a weight and color composition percentage of a first batch of mixed color cullet. The glass plant also receives a weight and color composition percentage of a second batch of mixed color cullet. The weight and color composition percentage of the first batch and the second batch are combined to generate a combined weight and composition percentage. The combined weight and composition are percentage are used to generate, automatically at a glass plant, a formulation to produce glass of a desired color.

1. A system for creating a batch of recycled glass from mixed color recycled glass cullet, the system comprising: a feeder to (i) transport a first batch of mixed color recycled glass cullet having a first color composition percentage from at least one stockpile, the first batch comprising at least two of flint, green, and amber glass and (ii) transport a second batch of mixed color recycled glass cullet having a second color composition percentage from at least one stockpile, the second batch comprising at least two of flint, green, and amber glass;a raw materials supply feeder to transport at least one glass raw material element;mixing/melting equipment connected to the feeder and the raw materials supply feeder to receive the first batch, the second batch, and the raw material element; anda batch controller in communication with the mixing/melting equipment, the feeder, and the raw materials supply feeder, the batch controller to: receive target specification data for mixed color recycled glass cullet;control the mixing/melting equipment and the feeder to generate a third batch of mixed color recycled glass cullet, the third batch being consistent with the target specification data and having a third color composition percentage, by blending a first amount of the first batch with a second amount of the second batch, the first amount calculated at least in part based on the first color composition percentage, and the second amount calculated at least in part based on the second color composition percentage;control combination of a portion of the third batch with plant scrap transported by the feeder from a plant scrap supply to form a further color composition; andcontrol adjustment of the further color composition by combining at least one raw material element transported by the raw materials supply feeder with the third batch and the plant scrap. 2. The system of claim 1, further comprising a glass coloring oxide agent adder, wherein the batch controller is further adapted to: control production of glass using at least a portion of the third batch;determine a glass coloring oxide agent level to produce a desired color of a glass product, the glass product comprising at least a portion of the third batch; andadd glass coloring oxide agent from the glass coloring oxide agent adder to the mixing/melting equipment. 3. The system of claim 2, wherein the batch controller controls adding copper oxide from the glass coloring oxide agent adder to the mixing/melting equipment. 4. The system of claim 2, wherein the target specification data comprises a desired transmission property. 5. The system of claim 4, wherein the batch controller is further adapted to determine the glass coloring oxide agent level to produce the desired transmission property. 6. The system of claim 1, further comprising an optical imaging device adapted to analyze at least one of the first color composition percentage, the second color composition percentage, and the third color composition percentage. 7. The system of claim 1, wherein the batch controller is further adapted to store at least one of the first color composition percentage, the second color composition percentage, and the third color composition percentage. 8. The system of claim 1, wherein both the first color composition and the second color composition comprise a flint glass percentage, a green glass percentage, and an amber glass percentage. 9. The system of claim 1, wherein the target specification data comprises at least one of a color specification, a purity specification, and a contaminant specification. 10. The system of claim 1, wherein the third batch comprises a specification that is at least one of equal to a value specified by the target specification data and within a percentage range specified by the target specification data. 11. The system of claim 1, wherein the third color composition percentage is consistent with a color specification of the target specification data such that the third batch can be used in a glass production process, wherein a glass coloring oxide agent level is determined for the glass production process before the third batch is generated. 12. The system of claim 1, wherein the feeder comprises a vibrating conveyor belt. 13. The system of claim 1, wherein the feeder comprises a first feeder adapted to transport the first batch and a second feeder adapted to transport the second batch. 14. A system for creating a consistent feed stream of mixed color recycled glass cullet, the system comprising: a first separator for removing contaminants from a first batch of recycled glass, the first batch of recycled glass comprising at least two of flint, green and amber glass;a second separator for separating a first portion of glass from the first batch of recycled glass, the first portion of glass comprising pieces of glass greater than approximately 0.625 inches in size;a crushing apparatus for crushing the separated first portion of glass to a piece size of less than approximately 0.625 inches;a measuring apparatus for measuring a first color composition percentage of the first batch of recycled glass after the crushed first portion is returned to the first batch of recycled glass;a feeder to (i) transport the first batch from at least one stockpile and (ii) transport a second batch of mixed color recycled glass cullet having a second color composition from at least one stockpile;a raw materials supply feeder to transport at least one glass raw material element;mixing/melting equipment to receive the first batch, the second batch, and the raw material element; anda batch controller in communication with the mixing/melting equipment, the feeder, and the raw materials supply feeder, the batch controller to: receive target specification data for mixed color recycled glass cullet;control combination of at least part of the first batch of recycled glass with at least part of the second batch of recycled glass, the combination generating a third batch of recycled glass having a third color composition percentage, the third color composition percentage being consistent with the target specification data;control combination of at least part of the third batch of recycled glass with plant scrap received from a plant scrap supply to form a further color composition, andcontrol adjustment of the further color composition by combining at least one raw material element received from the raw materials supply feeder with the third batch of recycled glass and the plant scrap. 15. The system of claim 14, wherein the measuring apparatus comprises an optical imaging device. 16. The system of claim 14, wherein the batch controller is further adapted to store at least one of the first color composition percentage, the second color composition percentage, and the third color composition percentage. 17. The system of claim 14, wherein both the first color composition and the second color composition comprise a flint glass percentage, a green glass percentage, and an amber glass percentage. 18. The system of claim 14, wherein the first separator comprises at least one of a magnetic separator, an air classification system, and an eddy current separator. 19. The system of claim 14, wherein the second separator comprises a screen. 20. The system of claim 14, wherein the crushing apparatus comprises a jaw crusher forming an aperture between two reciprocating plates.
