Cobalt Oxide imparts Blue colour to the glass. The addition of oxides, sulfides, salts and other compounds of different metals to molten glass at the time of manufacture adds colour to the glass. The introduction of electrically charged ions which are evenly distributed in the glass during manufacture also gives the glass a characteristic colour.
