    • 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 % CsO. 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.

    • Microwave radiation of frequency 0.1 to 20 GHz, from any direction, is applied to the melt of viscosity in the range 10 to 10 Pa.s. The outside surface of heated space, where an outlet of the of the waveguide (11) of microwave radiation is located, can be cooled. The microwave radiation in the melt is being reflected by the reflective metallic elements in the melt back to the place of radiation entry into the melt and its shielded from the surroundings by shielding metallic element. There shall be an outlet of at least one waveguide (11) from the source (10) of the microwave radiation, in any direction to the outside surface of the melt, into the space with the melt of a given viscosity. At least one waveguide (11) is led to the outside surface of the bottom (13) of the channel (1) of the forehearth and/or to the outside surface of the bottom (14) of the metallic casing (3) of the channel (1) of the forehearth and/or to the outside surface of the bottom (17) of the basin (16) of the working end of the furnace and/or tothe side walls of the basin (16) of the working end of the furnace, possibly also above the surface of the molten glass (8) or above the roof (5) of the channel (1). Waveguide (11) entry can be equipped with insulating layer (2). Reflective metallic elements can be immersed into the melt. The space with the melt has square, rectangular, round or oval cross-section in the direction perpendicular to the longitudinal axis of the space.
