Abstract: Glasses are disclosed having a composition comprising the following oxides (in weight %): SiO2 61 to 70%, Al2O3 0 to 9%, Na2O 10 to 13%, K2O 0 to 1%, MgO 2 to 6%, CaO 6 to 16%, SrO 0 to 1%, ZrO2 0 to 1%, TiO2 2 to 15%, the glasses having a strain point greater than 570° C. The glasses have good dimensional stability at high temperatures, making them suitable for fire protection glazings and substrates which are processed at elevated temperatures, e.g. substrates for display panels, information storage discs and semiconductor devices, including photovoltaic cells. Physical properties of the glasses, such as thermal expansion coefficient, density and refractive index, are disclosed, as are the melting and liquidus temperatures. The glasses are suitable for manufacture by the float process, yielding flat glass in the form of sheets.
