Chemical composition of glasses, glazes, or vitreous enamels

Note

In groups C 03 C 1/00 to C 03 C 14/00, in the absence of an indication to the contrary, classification is made in the last appropriate place. [4]

Ingredients generally applicable to manufacture of glasses, glazes or vitreous enamels

Pretreated ingredients

Opacifiers, e.g. fluorides or phosphates; Pigments

to produce non-uniformly pigmented, e.g. speckled, marbled, or veined products

to produce crackled effects

to produce uniformly-coloured transparent products

Glass compositions (glass batch compositions C 03 C 6/00) [4]

Note

If silica is specified as being present in a percent range covered by two of the groups C 03 C 3/06, C 03 C 3/062 or C 03 C 3/076, classification is made in both groups. If the range is covered by the three groups, classification is made in group C 03 C 3/04 itself. [4]
