        3 CATEGORIES
        
        Discrete processes
        
        Piece Ware Shaping Processes
        
        Pressing: - for mass production of flat products such as plates, dishes
        
        glass formed by application of pressure
        
        mold is steel with graphite lining
        
        Press-and-blowing : - for production of wide-mouth containers such as jars
        
        Blow-and-blowing : - for production of smaller-mouth containers such as beverage
        bottles and incandescent light bulbs
        
        Casting : - for relatively massive objects such as large astronomical (telescope) lenses and mirrors that must cool very slowly to avoid cracking
        
        Continuous processes
        
        Shaping of Flat Glass --Drawing
        
        Rolling of flat plate
        
        Float Process
        
        Shaping of Tubular Glass-Drawing
        
        Danner process
        
        Fiber-making process
        
        Fibrous glass for thermal insulation, acoustical insulation,and air filtration, in which the fibers are in a random,wool-like condition
      - Raw materials preparation
        
        The principal component in nearly all glasses is silica (SiO2)
        
        Raw materials – also named as starting material
        
        Glass melting
        
        The batch of starting materials to be melted is called a charge
        
        Melting temperature for glass are around 1500 °C to 1600 °C
        
        The viscosity of molten glass is inversely related to temperature
