Abstract

A soda lime silica glass suitable for forming by the float process is disclosed, having a composition containing 6- 12.4 wt % Na2O and 10.2-17 wt % CaO. The glass may also contain 68-75 wt % SiO2, 0-4 wt % A12O3, 0-3 wt % K2O, 0-5.5 wt % MgO. 0-2 wt % Fe2O3 and 0-0.5 wt % SO3. Compared with a typical known commercially produced soda lime silica glass, the proportion of Na2O is reduced in order to reduce raw material costs, and the proportion of CaO is increased. CaO and MgO may be adjusted relative to each other according to limestone and dolomite prices in the manufacturing locality: The above oxides are also adjusted to maintain the physical and optical properties of the glass as close as possible to those of the typical glass, two exceptions being the liquidus temperature, which is higher than the typical glass, and the fracture toughness, which is lower, and results in improved toughenability.
