The size is approximate number, there is a slight error in manual blowing










We use High Borosilicate heat-resistant glass material. Compared with the traditional cover glass molecular density is closer, only a smaller thickness can achieve better strength. Therefore, the sound is relatively crisp and feels lighter. Generally, heat-resistant glass is not very thick, because many tea ware can be heated by open flame. If the temperature inside and outside is thick, the heat insulation is too good, the effect of open flame heating and heat preservation cannot be well achieved, and the thinner the glass is, the less likely it is to burst during normal use, because the instantaneous temperature from the inside to the outside will be smaller. The difference between high temperature resistant glass products and ordinary glass products is that high temperature resistant glass is light, more transparent than ordinary glass, easy to clean, strong corrosion resistance and strong thermal endurance. There will be no problem if you put ice water and then put boiling water.
