What Are the Different Materials of Glass Cups?
At present,there are two kinds of glass cups on the market, one is sodium calcium glass, the other is high borosilicate glass, the two kinds of materials are obviously different.
The surface of the sodium-calcium glass container is smooth and transparent. The surface of the high borosilicate glass container has a scratch like pattern. Many properties of general sodium calcium glass is not as high as borosilicate glass, high borosilicate glass material is short, forming more difficult. High borosilicate glass is more suitable for making water cups.
Sodium calcium glass (tempered except) in the general 80 degrees, that is to say, in winter to sodium calcium glass (tempered except) container inside pouring boiling water, will crack, but high borosilicate glass will not. High borosilicate glass cold and heat impact is better than sodium calcium glass (tempered except), high borosilicate glass cold and heat impact is generally in 100 degrees to 200 degrees and so on.
For example, the seasoning jar used in the home is mostly sodium calcium glass, but the water cup class, especially the water cup without the opposite structure most USES is high borosilicate glass.
