2013-4-23  CHEMISTRY OF GLASS MANUFACTURE In general terms, soda-lime-silica glass manufacture involves melting the required raw material mix at 1600°C, which yields a very fluid melt, from which gases can escape (especially carbon dioxide produced by the decomposition of carbonate raw materials). The glass is then worked to produce the articles required at about 1000°C, followed by annealing at 500-600°C. Example; the float glass process, used to produce flat panes of glass

34.3 Calcium silicate bricks. To make calcium silicate bricks, silica sand is mixed with high calcium lime at a sand–lime ratio of 10 or 20. The mix is then compressed into moulds and “autoclaved” at about 170°C (340°F) for several hours. Some gel, similar to the calcium silicate hydrate gel of the type that is formed by cement, is formed, and this
