1.	Describe briefly the major techniques applied on the molten glassobtained during the manufacture of glass to get the desired variety of glass.
Answer» Solution :The major techniques applied on the molten GLASS obtained during the MANUFACTURE of glass to get thedesired variety of glass are : (i) Blowing of glass : This technique is used for the manufacture of laboratory glass ware, bottles ETC. (II) Optical glass: Molten glass is pressed into circular shape from which differentoptical glasses aremanufactured. (iii) SHEET glass: Molten glass obtainedfrom the glass tank furnace is placed on molten bath of tin. The molten glass spreads on the bath of molten tin withuniform thickness from which sheet glass/gloat glass is drawn.
