Glass is an inorganic solid material that is usually clear, or translucent with different colours. Glass blowing was invented during the 1st century BC by the glassmakers of Syria. On March 25, 1902, Irving W Colburn patented the sheet glass drawing machine, making the mass production of glass for windows possible. On august 2, 1904, a patent for a ‘glass shaping machine’ was granted to Michael Owen. The immense production of bottles, jars etc. owe its inception to this invention.
