Abstract

A glass composition, for use in forming reinforcing fibres, comprises by weight, 38 to 46% silica, 8 to 15% aluminium oxide, 15 to 30% calcium oxide, 1 to 8% zirconium oxide, 0 to 10% magnesium oxide, 4 to 11% iron as Fe2O3, and 2 to 6% R2O, where R represents sodium, potassium or lithium, the balance, if any, consisting of compatible constituents. There is also provided a process for producing alkali-resistant glass fibres wherein a melt is produced from a mixture containing basalt rock, a calcium-containing compound and a zirconium-containing compound, and the melt is blown or spun into fibres.
