How to choose glass cookware
Glass cookware can be divided into ordinary glass teapots and heat-resistant glass teapots. Ordinary glass teapot, exquisite and beautiful, made of ordinary glass, heat resistance of 100℃-120℃. Heat-resistant glass teapots are made of high borosilicate glass. They are generally blown by hand. The yield is low and the price is more expensive than ordinary glass.
Glass teapot is a kind of tea set used by many people who make tea, because it is not as deep in water as purple sand, and the quality standard is not constant like ceramics. Inferior and chemical synthetic porcelain are often bought. The glass material is transparent, high brightness and fashionable, and it is easy to make any tea without leaving any peculiar smell, easy to clean after use, and easy to take care of. This has become the reason why glass teapots are popular.
A good glass teapot can withstand high temperatures and can be heated by an open flame with heating tools such as alcohol stoves and candles and will not burst. The heat dissipation speed of thick glass is not as fast as thin glass. When boiling water is poured in, the inside of the cup wall is heated first and expands rapidly, but the outer surface does not expand at the same time, so it breaks. When a thin glass is poured into boiling water, the heat can be quickly dissipated, and the body of the cup expands evenly and synchronously, so it is not easy to burst
