Brife introduction for glass teapot

To select a particular teapot for the particular tea, is gradually becoming a habit of tea lover. The glass teapot is transparent and bright. It can be used watching the beautiful and stretched shape of the tea while make and taste tea in the tea set, which is becoming more and more popular.
The glass teapot seems simple, but in fact it contains a great deal of knowledge. 

How can I choose a good glass jug?
First, it depends on the thickness of the glass wall. Most of the teapots on the market are made of high-silicon glass, and they have professional technical standards for the thickness and weight of the glass wall. A good glass teapot is resistant to high temperatures. It can be heated by an open flame with alcohol stoves, candles and other heating tools without bursting. It can also be taken out of a cold environment and immediately filled with boiling water. However, if the glass wall is too thick, it will lead to a better thermal insulation effect, which will not play a good role in heat preservation by open flames, and the thinner the glass, the less likely it is to burst.
Secondly, it depends on the lid of the glass teapot. Because glassware is not a pressure-resistant container that can withstand pressure, if the lid is too tight, it will be sealed. When the internal temperature of the pot changes, the air part will expand and contract, and the pressure difference will not be balanced. The entire glass teapot It becomes a pressure vessel and bursts once the pressure resistance is exceeded .Again, it depends on the overall structure of the glass teapot. Structure is an important consideration for any kind of teapot, and glass teapots are no exception. The structure of the glass teapot includes the overall coordination of the pot body, spout, lid and handle, and has a smooth and rounded aesthetic sense. 

Finally, it depends on the blowing technology of the glass teapot. In general, hand-blown glass teapots are more valuable than mechanical ones. Manual blowing is to use the plasticity of glass in a certain temperature range. It is usually completed by the cooperation of several people. After blowing out the ball, it must be shaped by scissors, molds and other tools.
