There are a number of ways of categorizing glass. This overview of glass types looks at the way the glass is manufactured.
Crown glass is the oldest method of producing sheet glass.
Cylinder glass is also a hand made process that includes broad sheet glass.
Flashed glass was a development to make dense colours more transparent and as a by-product allowed much greater detail by abrading and etching.
Industrialization of glass production began with the development of drawn glass and table glass.

The glass that we now rely on for large clear windows began with the development of floating glass on molten metal, hence the name float glass.  Toughened/Tempered glass and laminated glass are two among many methods of providing greater strength to glass.
