The size is approximate, with slight errors due to hand-blown production.










We use high-borosilicate heat-resistant glass material. Compared with traditional glass, the molecular density of this material is more compact, and it can achieve better strength with a smaller thickness. Therefore, the sound when knocking is clearer and the feel is lighter. Generally, heat-resistant glass is not made very thick because many tea utensils can be heated directly over a flame. If it is too thick, the temperature insulation inside and outside will be too good, which will not allow the effect of maintaining heat from the direct flame heating to work well. Moreover, the thinner the glass is, the less likely it is to burst normally 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 lies in that the former is lighter, has higher transparency, is easier to clean, has stronger corrosion resistance, and has stronger temperature resistance. Placing ice water and then boiling water will not cause any problems.
