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..
