The Microfloat Process
The float process, which was developed by a British company and first used in the 1950s, revolutionized the world of glass at the time. Since then, the term "float glass" has been synonymous with virtually flawless flat glass and a mirror-like surface quality, available in large sizes.
|
In the float process, molten glass flows continuously from the melting tank on a bath of liquid tin. There it spreads out uniformly and then undergoes mechanical treatment to produce the required thickness. When it reaches the end of the tin bath, the glass, which has now "solidified", is removed from the surface of the metal and then annealed to relieve any internal stress. After it leaves the annealing oven, the glass ribbon is cut into the required sheet sizes by an automatic cutting device.

In 1993 SCHOTT - in cooperation with a Japanese partner - constructed the world's first Microfloat facility for the production of BOROFLOAT® 33 - the unique borosilicate special float glass - in Jena (Germany).
