This process involves pouring recycled glass, silica sand, lime, potash and soda from a furnace onto a large bed of molten tin. This mixture slowly solidifies over the molten tin as it enters the annealing oven where it travels along rollers under a controlled cooling process. From this point the glass emerges in one continuous long ribbon where it is then cut and further processed to customer specification. Float glass is also known as soda lime silicate glass as these are the major components used in manufacture.
Clear float glass is colourless and transparent when viewed face on. When viewed on edge, it displays a slight green tinge. Clear float glass offers a very high level of natural daylight or visible light transmittance to pass through it.
