A method of forming fibres comprising SrO, Al<2>O<3>, and a fibre forming additive, the method comprising the steps of either: a) mixing: i) a compound of strontium which on heating loses a volatile component, ii) Al<2>O<3>, and iii) a fibre forming additive; b) calcining the mixture to remove the volatile component; c) melting the calcined mixture or: a) mixing: i) a compound of strontium which on heating loses a predominantly non-toxic volatile component, ii) Al<2>O<3>, and iii) a fibre forming additive; b) forming granules from the mixture of a sufficient size to resist ejection from a melt by outgassing; c) melting the granules and extracting the predominantly non-toxic volatile component either followed by: d) disrupting the melt to form fibres.
