Why is the purple teapot covered with cloth?

It is suggested that the sealing performance of tea cans should be better and the cloth cover should be tighter.

Purple sand is a special kind of clay, which has no glass glaze on its surface and can be used directly after sintering. Therefore, compared with porcelain, purple sand cans have certain air permeability.

Under the general tea storage conditions, even if the purple sand itself has certain air permeability, the air exchange ratio inside and outside the pot will not be particularly high, because the purple sand still has a certain density.

But tea lovers need to pay attention to the fact that the weather is humid every spring, especially when they return to Nantian. At this time, the moisture in the air will more or less enter the jar through the pores of the purple sand, causing the tea leaves to be damp and moldy. Therefore, it is not recommended to store tea in purple sand cans in spring, and it can be stored in kraft paper bags.

Note: Generally speaking, tea cans should have good sealing performance, moisture-proof, light-proof, odor-proof and oxidation-proof performance. Such teapots are all good containers for storing tea. Here is how to choose several common tea cans:

2. Wooden teapot: Good sealing, moderate price, suitable for general tea storage, but not moisture-proof.

3, paper tea cans: general sealing performance, low price, suitable for public use. This teapot is not suitable for storing expensive tea leaves. Drink tea as soon as possible after it is in full bloom, and it is not suitable for long-term storage.

4. Stainless steel teapot: good sealing, moderate price, good moisture-proof and light-proof performance, suitable for storing ordinary tea at home.

5, tin tea cans: good sealing, dark, moisture-proof, odor-proof, suitable for storing more expensive tea. But the price is too high and the cost performance is not good.
