.~.~ By molten glass comminuting
DEFINITION
Classification: 65/21.2
By molten glass comminuting:
(under subclass 21.1) Processes wherein glass in molten state is comminuted to form discrete particles and is solidified in its comminuted form.
(1) Note. To be classified in this subclass the material must be subdivided from an original liquid mass and then the subdivided particles solidified with no substantial change in shape and size.
(2) Note. Particles formed by a molten glass stream entering a liquid quenching both are not proper for this subclass since no distinct liquid particles are formed which are subsequently solidified.
