Whats so picky about a broken glass teapot?i8p风水,八字,解梦-玄空网

　　 there are two ways: first, put a teaspoon in the cup. When boiling water is poured into the bottom of the cup, the boiling water distributes some of the heat to the metal teaspoon of the good conductor before there is time to heat the glass (inferior thermal conductor). As a result, the temperature of boiling water decreases, changing from boiling water to hot water, which does not hinder the glass. As for the continuous pouring of boiling water, it is not so terrible for the cup, because the cup is already a little hot in time. Method 2. Boil the glass in water for 一0 minutes. When the glass is uniformly heated, it will not produce very strong pressure, nor will it cause the cup to break. Or you can rinse the cup with a little hot water before filling it. It wont burst when you pour hot water. Photo: the glass teapot will break when boiling water: due to the uneven expansion of the glass, the boiling water will break the glass. When hot water enters the cup, the inner and outer walls of the cup cannot be heated at the same time. At first, only the inner wall of the cup is heated, while the outer wall remains cool, causing the inner wall to expand rapidly and the outer wall to remain intact; therefore, the outside will be subjected to strong internal pressure to break the glass.i8p风水,八字,解梦-玄空网
