Introduction Glass types and manufacture The float process Float glass > Step 1 The mixed batch of raw materials is continuously run into the The float glass process was invented by melting furnace. Pilkington, and the first float line in Australia was commissioned in 1972. CSR building products purchased the Pilkington Australia business in 2007 and continues to both invest in the process and set the world standard for the production of Laminated glass is held Toughened glass fragments together when broken. into small blunt-edged pieces high quality float glass. when broken. Glass is manufactured by melting sand, soda ash, Laminated safety glass dolomite and limestone together and produces Comprises two or more layers of glass > Step 2 At the furnace exit the glass a continuous glass ribbon up to 3660mm wide. permanently bonded together with an interlayer forms a ribbon floating on the surface This flows from the furnace and ‘floats’ over a of molten tin. or resin. If broken, the interlayer is designed to bed of molten tin. It is then carefully cooled to hold the glass together. Virtually all glass types anneal the glass – a process which modifies the can be laminated and the thickness and type internal stresses enabling it to be cut and which of interlayer can be varied to provide safety, maximises its potential mechanical resistance. ballistic, bomb or physical attack resistance. The float glass process is renowned for flatness Normal laminated glass can be cut and and optical clarity. It is available in clear, toned, further processed. high performance toned, ultra clear low iron glass Toughened safety glass and Low E pyrolitic coated.
