Zisha artists use steel knives to carve landscapes, insects, fish and calligraphy stones on the pot body, making Zisha pot a work of art integrating literature, calligraphy, sculpture, painting, stone carving and modeling. While enjoying tea, we can also appreciate its art, giving people the enlightenment of knowledge and the enjoyment of beauty. The height and caliber of teapot are different, which has a lot to do with making tea. Purple clay pots are generally suitable for soaking oolong tea; A teapot with a high mouth and a small mouth is suitable for making green tea or scented tea to make it brown.
Green and mellow. Purple sand tea sets not only pay attention to modeling, but also pay attention to tea management, which is full of fun. Therefore, people regard it as "the first tea set in the world" and have the reputation of "famous pottery, no class in the world". Compared with other tea sets such as porcelain, it has incomparable advantages, which is why teapot is used to make tea.
(1) Make tea in a teapot, and the tea is rich and lasting. The teapot mouth is small, the lid is tight, and the inner wall of the teapot is rough, which can effectively prevent the premature loss of fragrance. Long-term use of purple sand teapot, the inner wall hung with a layer of brown-red tea rust, when in use.
The longer the time, the more tea rust accumulates on the inner wall, so the more alcohol and fragrance are added to the tea soup after making tea. Long-term use of purple sand teapot, even if you don't put tea leaves, just pour boiling water, still exudes attractive fragrance, which is beyond the reach of ordinary tea sets.
(2) Making tea in a teapot is not easy to carry and hold. The linear expansion coefficient of teapot is slightly higher than that of porcelain teapot, so there is no glaze stress. After firing, there is very little glass in the teapot, which is enough to overcome cold and heat.
The sudden change ability caused by temperature difference makes its heat transfer slow. Purple sand teapot has excellent adaptability to sudden changes in heat and cold. Even if it is cooked at the high temperature of Baidu, it will soon fall into the ice and snow below zero and will not burst. Therefore,
Making tea with a teapot is not convenient to carry and hold; In the cold winter, if you make tea with boiling water, you don't have to worry about cracking, even if you put it on a slow fire, there is no danger of cracking.
(3) Tea is brewed in a teapot, and the heat preservation time is long. There are many small bubbles on the wall of the teapot, which are filled with stagnant air, which is a poor conductor of heat, so the teapot has good heat insulation performance.
(4) The purple sand teapot is not glazed inside and outside, keeping tiny pores, and has good air permeability, but it is impervious to water and has strong adsorption, which is incomparable to ordinary teapots. The aromatic oil in tea leaves can be kept volatile when heated.
It forms fragrance, improves the acidity in the later stage of tea soup, and has astringent and bactericidal effects. Therefore, it can delay the deterioration of tea slightly, and the so-called "staying in summer without deterioration" is the truth.
