As a manufacturer of soda ash, Solvay is an acknowledged partner of the glass
industry. It is less well known that a whole range of inorganic fluorine compounds
plays an important role both in the manufacture of glass and in its processing.
In the manufacture of opaque glass, also known as milk or cloud glass, the
cloudiness is achieved by the addition of inorganic fluorides. These are added to
the glass melt as so-called “white opacifier”.
In small amounts, fluorides act as fluxes, and only the addition of larger quantities
brings about the clouding effect. This clouding effect is caused mainly by the
precipitation of small crystals of calcium and sodium fluoride. A typical fluoro-
opaque glass will have a fluoride content of approx. 3.5 – 4.0 %.
