Glass frit with iron selenide complex

1 . A colored glass comprising:

a base material; and

a colorant including Fe 2 O 3 and Se;

wherein the Fe 2 O 3 and Se are combined as a Fe 2 O 3 —Se complex before being added with the base material.

2 . A colored glass having a base and a colorant, wherein the composition of the colorant comprises:

Fe 2 O 3 ; and

Se;

wherein Fe 2 O 3 and Se are combined to form a Fe 2 O 3 —Se complex within the colorant for reducing the amount of Se volatilized during a colored glass making process.

3 . The colored glass of claim 2 wherein a weight of the Fe 2 O 3 is at least 70% of a weight of Se added.

4 . A method of reducing a volatilization of Se within a glass batch when forming colored glass, the method comprising the steps of:

supplying a plurality of substances to a mixer for forming a glass batch;

supplying a Fe 2 O 3 —Se complex to the mixer to be added to the glass batch; and

heating the combined glass batch and the Fe 2 O 3 —Se complex for forming the colored glass, the Fe 2 O 3 —Se complex reducing volatilization of Se during the processing of the colored glass.

5 . The method of claim 4 further comprising the step of supplying MnO 2 to the glass batch for reducing volatilization of Se during the processing of the colored glass.

6 . The method of claim 4 wherein the Fe 2 O 3 —Se complex is added to the glass batch as part of a colorant.

7 . The method of claim 6 wherein the colorant including the Fe 2 O 3 —Se complex is added to the glass batch in a colorant forehearth.

8 . The method of claim 7 wherein the colorant including the Fe 2 O 3 —Se complex is blended with the glass batch by stirring the colorant including the Fe 2 O 3 —Se complex into the glass batch to homogenize the color.

9 . The method of claim 4 further wherein MnO 2 is added to the glass batch as part of the plurality of substances.

10 . The method of claim 4 wherein the Fe 2 O 3 —Se complex is provided into a batch feeder of the furnace for mixing the Fe 2 O 3 —Se complex and the glass batch.

11 . The method of claim 4 wherein at least a portion of the Fe 2 O 3 —Se complex is added to the mixer as a cullet.

12 . A method of retaining selenium in colored glass during a processing from a glass batch raw material stage to the time of fabrication of the colored glass which comprises mixing the glass batch with a colorant that includes a Fe 2 O 3 —Se complex.
