Abstract:
A method of creating recycled glass products of a particular color from raw materials including mixed color glass cullet, said mixed color glass cullet including at least two of green glass, amber glass, and flint glass, comprising the steps of:specifying the oxide composition percentage of said at least two of said green, amber, and flint glass in said mixed color glass cullet; specifying the particular color and transmission properties of the recycled glass products; specifying a quantity of said mixed color glass cullet to be melted as a fraction of total glass in a batch from which said recycled glass products are to be created; specifying a percentage composition of each of said at least two of said amber, green, and flint glass in said mixed color glass cullet; calculating using said percentage composition the desired glass coloring oxide agent levels of glass of said particular color with said specified transmission properties; calculating a batch composition of said recycled finished glass, said batch composition including said mixed color glass cullet and amounts of said glass coloring oxide agents suitable to adjust final glass coloring oxide agent levels to said desired glass coloring oxide agent levels for glass of said particular color with said specified transmission properties; and creating recycled glass products from said calculated batch composition.
