- Glass is a substance of variable composition, which for simplicity is expressed by convention in terms of oxide of the constituents’ elements (SiO2, Na2O, CaO, B2O3, etc). Although conventionally, glass compositions are expressed as oxides of the different components, glass is a non-crystalline or vitreous inorganic macromolecular structure, which does not contain the chemical components of the different raw materials.
The glass classification is normally made considering the chemical composition. The DRAFT GLASS BREF gives four main categories:
• soda-lime-silica glass
• borosilicate glass
• lead crystal glass
• specialty glass
The principle glass compositions for each common type of glass are shown below. As stated glass may contain minor constituents but these are normally below 1%. This dossier should not be interpreted as covering glasses where such minor constituents exceed 1% unless supported by test evidence.
Soda-lime-silica glass represents more than 95 % of the glass produced in Europe. A typical soda-limesilica glass composition is normally included between the following percentages:
• 71-75 % silicon dioxide (derived mainly from quartz sand)
• 12-16 % sodium oxide (mainly from soda ash)
• 10-15 % calcium oxide (mainly from limestone)
• 0.5-3 % aluminium oxide (mainly from feldspar or oxides of aluminium)
Low levels (normally below 1 % w/w) of other components can be present to impart specific properties to the glass. - Conclusions:

- Glass is fundamentall non-crystalline solids characterised by a lack of translational order of their atomic structure. Glass is also characterized by the absence of any microstructure. It is an essentially isotropic material without any internal phase boundaries. From a thermodynamic point of view, glass is an undercooled frozen-in liquid.
From the REACH point of view, glass is an UVCB substance and not a mixture. The industrial glass is made of the following raw materials: sand (SiO2), feldspar (NaAlSi3O8), dolomite (CaMg(CO3)2), limestone (CaCO3), soda ash (Na2CO3) and some other oxides in small quantities.
The raw materials are simplified as pure substances featuring the man pahse of real raw material only. The resulting glass has an oxide omposition expressed in terms of SiO2, MgO.... which is a realistic representative of a typical container glass, but it should be kept in mind that glass present no internal phase boundaries. Some of the raw materials available may be classified as harmful. But during the melting process, the raw materials lose their identities as individual substances and form a homogeneous melt. Their chemical properties are no longer reflected by the resulting glass. The individual entities form building blocks (at the atomic scale) of a new non-cristalline matrix that chemically behaves in a way different from any of the raw materials. Chemically, the matrix as a whole behaves like a substance of its own. - Conclusions:
- Glass under REACH is an UVCB substance. During the melting process, the raw materials lose their identities as individual substances and form a homogeneous melt. Their chemical properties are no longer reflected by the resulting glass.
It is exempted from registration under the entry 11 of the REACH annex V. - Executive summary:
Glass under REACH is an UVCB substance. During the melting process, the raw materials lose their identities as individual substances and form a homogeneous melt. Their chemical properties are no longer reflected by the resulting glass.
It is exempted from registration under the entry 11 of the REACH annex V.
