Product Description

Our tempered borosilicate float glass is made up of about 15% boron trioxide, which is that magical ingredient that completely changes the behavior of glass

1.  makes it thermal shock resistant and fireproof. This allows the glass to resist extreme changes in  emperature and is  measured by the "Coefficient of Thermal Expansion," the rate at which the glass expands when it is exposed to heat. Thanks to  this, borosilicate glass has the ability to go straight from a freezer to an oven rack without cracking.
2.  makes it more clearer (with more than 95% light transmittance at 6mm thickness)than low iron glass
3.  makes it 2 times stronger  than normal  tempered float glass
4. doesn't makes it  spontaneous broken or explosive
