Float Glass - Annealed


The Float glass process is the most common process of glass production. The process involves the melting of the raw ingredients (silica, lime and soda) in a furnace and floating it on a large bed of molten tin. The mixture slowly solidifies over the tin as it enters the annealing oven where it is slowly control cooled. The glass exits the oven as one large sheet after which it is cut to meet the customer's needs. The speed at which the glass is drawn over the tin bath controls the thickness which ranges from 2 to 19mm.

As suggested by the name, clear float glass has a high level of transparency and offers a high amount of visible light transmittance.

Clear float glass can be further processed in order to emphasize certain characteristics. Examples are heat strengthened, toughened, laminated and insulating glass units.
