Float clear glass 1.More choices for thickness 2.Special dimensions as 3300x14000mm 3.Offer high visible light transmittance Float glass is a term for perfectly flat, clear glass (basic product). The term "float" glass derives from the production method, introduced in the UK by Sir Alastair Pilkington in the late 1950's, by which 90% of today's flat glass is manufactured. Production: The raw materials (silica sand, calcium, oxide, soda and magnesium) are properly weighted and mixed and then introduced into a furnace where they are melted at 1500° C. The molten glass then flows from the glass furnace into a bath of molten tin in a continuous ribbon. The glass, which is highly viscous, and the tin, which is very fluid, do not mix and the contact surface between these two materials is perfectly flat. When it leaves the bath of molten tin the glass has cooled down sufficiently to pass to an annealing chamber called a lehr. Here it is cooled at controlled temperatures, until it is essentially at room temperature. Float clear glass is made of molten glass which flows through tweel to tin bath and then to lehr. While floating through the molten tin, the glass under the works of gravity and surface tension becomes smooth and flat at both sides. Float clear glass is transparent and offers a high visible light transmittance. Clear float is sold as cut-to-size or bulk form. Clear float is also available in laminated,tempered and insulated form. Features: Smooth and flat surface and good vision. Flexible size specifications minimizing cutting loss. Substrata for each level of glass processing. Kindly glass offers a complete range of clear float glass products.
