In most modern works the greater part of these operations, as well as the actual rolling of the glass, is carried out by mechanical means, steam power and subsequently electrical power having been successfully applied to this purpose; the handling of the great weights of glass required for the largest sheets of plate-glass which are produced at the present time would, indeed, be impossible without the aid of machinery.
The following are typical analyses: The raw materials for the production of plate-glass are chosen.
Plate-glass is manufactured in this manner in thicknesses varying from 1 in.
Plate-glass was made by Messrs Cookson of Newcastle, and by the British Plate Glass Company of Ravenhead.
Thevart, he succeeded in perfecting the process of casting plate-glass.
