FIELD: technological processes.
SUBSTANCE: in method of production of glass coloured in mass, at least one of colouring agents or their mixture, or at least mixture of one of colouring agents with one or several raw components of furnace charge are preliminary mechanically activated in machines of highly intense grinding down to particle size from 10 to 100 nm, and in aggregated form - from 1 to 80 micrometer.
EFFECT: increase of glass colouring intensity and reduction of colouring agents escape extent in the process of boiling.
