The teapot is not glazed inside and outside, keeping tiny pores, with good air permeability, but impervious to water and strong adsorption, which is incomparable to ordinary teapot. It can keep the aromatic oil in Pu 'er tea volatilized by heat to form fragrance, improve the acidity in the later stage of tea soup, and play a role in convergence and sterilization. Therefore, it can delay the deterioration of tea slightly, and the so-called "not deteriorating until midsummer" is the truth. The teapot keeps warm for a long time. Because there are many small bubbles on the wall of the teapot, which are filled with stagnant air and are poor conductors of heat, the teapot has good thermal insulation performance.
