Glass

Hi folks,  
How are you? Welcome to my blog once again. A super cooled liquid made mainly from sand, glass is easily shaped, and forms clear, hard objects that remain untainted by chemicals. Glass objects are often mass-produced by the moulding process, in which jets of compressed air force molten glass into the shape of a mould. Sheet glass is made by the float-glass process, in which molten glass is floated on the surface of liquid tin and cut into lengths when cool. Thank you.
