COLORED GLASS

PROBLEM TO BE SOLVED: To develop oxidizing colored glass which can be colored by using a color feeder and has a desired yellow color stably. SOLUTION: The oxidizing colored glass contains erbium and praseodymium in an amount of 0.25-32 wt.% in total, each expressed in terms of Er2O3and Pr6O11, where...

Zusammenfassung:	PROBLEM TO BE SOLVED: To develop oxidizing colored glass which can be colored by using a color feeder and has a desired yellow color stably. SOLUTION: The oxidizing colored glass contains erbium and praseodymium in an amount of 0.25-32 wt.% in total, each expressed in terms of Er2O3and Pr6O11, where the weight ratio of Er2O3to Pr6O11is 0.15-1.7, and has a positive redox number value and a main wavelength λd of 570-590 nm. When coloration is performed by using frit, the specific gravity of the frit is set to be 3-3.4, and erbium and praseodymium are incorporated in an amount of 26-32 wt.% in total, each expressed in terms of Er2O3and Pr6O11.
