The term "float" refers both to a type of glass and to the process by which it is made.

  • Float glass is the basic glass from which almost all the flat glass products are derived. It may be clear or coloured, and is produced in large sheets (6 x 3.21 m) that are normally processed into secondary products.

  • The float process involves literally floating the molten glass on a bath of liquid tin, producing a perfectly flat surface on both sides.
