Which is better, high borosilicate glass and ordinary glass?

          The common glass in the market is soda lime glass (ordinary glass), tempered glass and high borosilicate glass. High borosilicate glass can withstand an instantaneous temperature difference of about 150°C, and can hold both hot and cold drinks safely. The main processes are manual blowing and semi-automatic assembly lines, as well as special pressing. Ordinary glass can only withstand an instantaneous temperature difference of 75 ° C, mainly used in cold beer, mainly the pressing process and iron pipe blowing process. Thicker tempered glass is generally not used for cups. The specific method for distinguishing high silicon boron is as follows:

         1. The bottom of the cup is pressed rather than high silicon boron;

         2. Double-layer glass cups, most of which are made of high borosilicate heat-resistant glass;

         3. The glass cup with handle is thin and light, and the thickness is generally high borosilicate glass;

         4. The water cups used in daily life are mainly artificially blown. The raw materials are mainly high borosilicate glass tubes, which are softened at high temperature, and then placed in the mold for rotary blow molding or fixed blow molding.
