The stability of teapot does not affect the quality of tea.

Zisha is the first of its outstanding tea sets because of its superior performance, its meticulous craftsmanship, the meticulousness of its embryos, and the advantages of Zisha itself. In winter, friends who do not use tea with a teapot may find that the tea is not fragrant. In fact, it is the tea set that has released the excess temperature because it senses the winter cold and it affects the taste of the tea. Zisha pot tea is not easy to degenerate hair, first benefit from the good breathability of purple sand material. Secondly, due to the tight precision produced by the teapot, which reduces the flow of mixed air into the pot, the time for the deterioration of tea juice is relatively delayed. This is due to the small shrinkage of the Zisha Mud, the molecular scales arranged, firing is not easy to deformation; and Zisha making fine, mouth, cover can be close, displacement tolerance can generally be controlled within 0.5 mm, and porcelain teapot lid Displacement tolerances are generally between 1 and 3 mm or even larger.

The coefficient of linear expansion of the teapot is slightly higher than that of porcelain, but due to the fact that neither the inner nor the outer surface is glazed, there is no concern about the stress of the glaze. The higher alumina content in the raw material makes the teapot with thermal shock resistance and high mechanical strength, which can overcome the stress caused by the hot and cold changes; therefore, in the winter and the lunar months, the injected water will not burst. Once the teapot is not used for a long time, it is forgotten to pour out the residue and leave a odor. So long as it is soaked in boiling water, it will be immediately immersed in cold water. Repeatedly, with the thermal expansion and contraction of the pot wall stomata, the double porosity of the pot wall can produce a replacement function when the heat is changed rapidly, eliminating the odor.
