Float glass is a sheet of glass made by floating molten glass on a bed of molten metal, typically tin, although lead and various low melting point alloys were used in the past. This method gives the sheet uniform thickness and very flat surfaces.
Clear Float Glass Main features:
1. High light transmittance, excellent optical performance.
2. Smooth and flat surface, visible flaw is controlled strictly
3. Easily to be cut, insulated, tempered and coated.
4. Thickness available from 3mm to 12mm. jasonglass (at) sina . cn
5. All the products are manufactured according to ISO 9001, to make sure perfect quality.


What is Borosilicate glass 3.3 :
Borosilicate glass is comprised mainly of silica (approx 80%) and boron (approx 13%). This type of glass melts at a higher temperature and has a shorter working time. It is an extremely versatile glass that is less dense than soda-lime and because of its molecular structure is also more durable.
Thermal expansion is a measurement of linear expansion which denotes how much the glass contracts as it is cooled.
Thermal expansion is another property that must be considered when discussing the uniqueness of borosilicate. Soda-lime glasses are at the highest end of the scale and expand the most as they are heated. This means that as they cool, they contract or shrink at the greatest rate. To prevent cracking, this rate of cooling must be carefully controlled using an annealing oven.
Borosilicate glass, however, is on the lower end of the thermal expansion scale. It expands and contracts at a much lower rate than soda-lime glass and is not as susceptible to cracking problems, even when cooled quickly without kilning. This is why borosilicate is used in the scientific industry as well as for cookware.

Characteristics:
Great heat resistance performance, stable chemical property
High light transmission
Various thicknesses
Wide optical application
