Ordinary glass is a mixture of sodium and calcium silicates and is made by heating a mixture of sand (essentially SiO 2 ) with sodium carbonate and calcium oxide in a furnace at around 1700K and cooling rapidl..

Elements in Sea - Apart from the salts which flow down to the sea waters due to weathering of the rocks, a variety of sources, such as land and sea volcanic activity, seismic activity, deposit large amounts of minerals and metals in the ocean. Some of these dissolve in..

As we have seen, glass is a mixture of number of silicates. Therefore, when heated, it does not melt at a fixed temperature. But, it softens gradually and hence can be moulded into any desired shape. It is this property that makes glass one of the widely used materia..

Since CO 2 is liberated in the initial stages, frothing is a common observation. All the CO 2 is driven out on continued heating and a clear viscous fluid mass is got. It is then poured into moulds of various shapes or stamped with die (a device for stamping, cutting, or moulding material into a..
