The float system emerged by fifties,at Great Britain.The innovator process,created by sir Alastair
Pilkington,was based on making the glass(or dough),not yet melted,floating on molten tin.Then,the gl -ass gets the desired thickness,it is cooled and cut.Also known as flat glass,the floats are excellent unif -ormity and have almost no distortion.
The float glass process was developed by Pilkington by 1952 and it is a worldwide standard for m -anufacturing high quality glass.
The product,that originally produced only 6mm thickness glass,currently produces glasses with thi -ckness that very between 0,4e 25mm.The raw material are mixed with accuracy and merged in the ov -en.The glass merged to approximately 1000℃,is continuously shed in a tank full of liquid tin,chemical ly controlled.It floats on the tin,spreading it evenly.
The thickness is controlled by the speed of the glass sheet that solidifies as it keeps advancing.Aft -er annealing(controlled cooling),the process ends with the glass having polished and parallel surfaces
Generally used in building,vehicles,home appliance and goods for decoration,the float glass are cu -rrently considered dominants in the glass industry all over the world.
