The material is borosilicate glass , and it's heat resistant glass, the advantage for our glassware is as follows:
Products Advantages:
1) Non-porous Heat Resistant glass. It won't absorb food odors, flavor or stains.
2) Higher resistance to mechanical shock: scratch resistant.
3) Extra resistant to thermal shock, the heat resistance up to 800
4) Higher resistance to corrosion.
5) Higher hygienic performance
6) Depth Manufacturer's Warranty
7) Can be used in oven, microwave, dishwasher, freezer, refrigeratory, induction cooker, etc.
The material advantage: special properties of borosilicate glass
1) excellent corrosion resistant
2) smooth, non porous surface
3) transparency
4) non catalytic effect
5) non-flammability               
6) no environmental risk
