FIELD: glass industry; methods of manufacture of the optical glass.
SUBSTANCE: the invention is pertaining to the field of glass industry, in particular, to the method of manufacture of the optical glass. The invention provides that the number of the remained bubbles with the diameter of 0.3 mm and more makes 0.005 pc/cm3 or less per the unit of the volume of the optical glass. Such optical glass is produced at regulation of the temperature of the torch butt surface for the synthesis of glass In the process of deposition of the glass particles by regulation of the ratio of the speed of the flow or the volume of the flow between the combustible gas and the gas, which is sustaining combustion. The technical problem of the invention is prevention of destruction of the torch used for the synthesis of the optical glass and provision of manufacture of the optical glass of the stable quality.
EFFECT: the invention ensures prevention of destruction of the torch used for the synthesis of the optical glass and provision of manufacture of the optical glass of the stable quality.
