70.03 - Cast glass and rolled glass, in sheets or profies, whether or not having an absorbent, reflecting or non-reflecting layer, but not otherwise worked. - Non-wired sheets : 7003.12 - - Coloured throu hout the mass (body tinted), opacified, flashed or having an absorbent, refl ecting or non-reflecting layer - - Other 7003.20 - Wired sheets 7003.19 7003.30 - Profiles This heading covers all types of cast glass and rolled lass provided it is in sheets (whatever the thickness and whether or not cut to shape), or pro les, whether or not having an absorbent, reflecting or non-reflecting layer, but not otherwise worked. B It includes : (A) Unworked plate glass. This is generally non-trans arent on account of its grained or rough surfaces. It may also be artifictally coloured in t e mass by means of metallic oxides or other salts. Surface ground or polished plate glass is excluded (heading 70.05). k' (B) A category of non-transparent glass which is more or less opacified in the mass and sometimes completely opaque. It is often made to resemble marble, porcelain (china) or alabaster in ap earance. Thxs e of glass is made in white, black and other colours, plain or veined, an is used for acing walls, for the manufacture of tops for washstands, counters, desks, tables, operating tables, etc., of tablets for gravestones, of advertising boards, signs, etc. P. S polishing on one or both unworked state this lass bear traces of sand resu ting rough surface in order to This type of glass may be intended for faces, but when so treated it is excluded shows marks resulting from contact from the casting. Certain opal facilitate fixing. f (C) A range of non-transparent glass, with an irre lar surface obtained durin manufacture. This grou includes rough cast glass, cathe a1 glass, hammered cathe a1 glass, etc.; f i ed-ro led glass having one surface impressed with patterns (stripes, diamond patterns, ri ges, etc.); corrugated lass and cast so-called anti ue glass i.e., glass contamin bubbles, or crackled on t e surface, or with other de lberate " efects "). Glass of t ese air types, which may also be coloured in the mass, is used for the windows of factories, warehouses, offices, bathrooms and, in general, all premises where light is required but with varying degrees of obscuration. r P P i % Owing to the nature of the processes by which they are made, the types of glass in this category are not rendered plane by further processing. As already stated, this heading covers only cast glass and rolled glass. In the rolling process, the molten glass is passed between rollers from which it emerges either as a continuous ribbon or in sheets or profiles. It is then carried mechanically into a lehr. Pass It is durin the castiug or rolling rocesses that the surfaces of figured, hammered, etc., impressed? In the casting methot either engraved casting tables or an en aved roller o m the patterns in the semi-molten lass. In the rolling method, the desired e fects are obtained by means of the final roller, whic is engraved. F % r es of lass described above ma have holes obtained during manufacture, or m y be The& late, gured, cathedral and simi ar types of glass are sometimes wired where protection wire against the danger of s linters on disintegration or breakage is required, thus d i n g it suitable for building purposes. %ired glass is almost always obtained by embedding a network of steel wire in the soft glass while it is being rolled. # Glass classified in this heading may have been flashed, generally with glass of another colour, during the rnanufacturin process or may have been coated with an absorbent, reflecting or nonreflecting Iayer, but not urther worked. f The heading excludes not on1 cast lass and rolled lass which, b reason of subsequent processin ,fall in other headings (e.g., headkg 7k05, 70.06, 70.f8 or 70.09), gut also safety glass (heading ?0.07) which may have been subject to rolling during manufacture.
