ABSTRACT:
A glass fibre product consists of less than 80% by weight SiO.sub.2 from 20 to 25% by weight of TiO.sub.2 and not more than about 0.1% by weight of alkali metal oxide, and is made by leaching with acid a glass fibre composition consisting of from 20 to 40% by weight of alkali metal oxide, from more than 12 up to 20% TiO.sub.2 and the balance to 100% of SiO.sub.2 and having a silica:titania ratio within a selected range.
