Producing copper ruby glass from a sulfide-free colorless molten glass with an iron oxide content of 0.01-0.15 wt.% comprises feeding the molten glass into a distribution channel in which copper and tin oxides are added while the oxygen partial pressure in the molten glass if 10 -> 7> to 10 -> 4>, forming the molten glass into glass objects and subjecting the objects to heat treatment to develop a ruby color. |
