Recently, purple clay teapots have seen rising prices in the auction market and are considered collectible "antiques." Especially, works by famous masters are often hard to come by, as the saying goes, "Why seek worldly jewels when Yixing purple clay is the true treasure?" So, what are the benefits of brewing tea with a purple clay teapot? The advantages are detailed below.

1. Brewing tea with a purple clay teapot results in a rich and long-lasting tea aroma.

The purple clay teapot has a small spout and a tight lid, and its inner wall is relatively rough, which effectively prevents the aroma from dissipating too quickly. With prolonged use, a brownish-red tea patina builds up on the inner wall. The longer it is used, the more patina accumulates, making the brewed tea more mellow and fragrant. Even if no tea leaves are added, just pouring boiling water into a long-used purple clay teapot will still release a delightful tea fragrance—something ordinary teaware cannot achieve. This is the most notable benefit of using a purple clay teapot for brewing tea.

2. Purple clay teapots are unglazed both inside and out, maintaining tiny pores that provide good breathability without leaking water, and they have strong adsorption capacity—features unmatched by ordinary teapots.

They help retain the aromatic oils released from tea leaves when heated, enhancing the tea's fragrance, increasing the late acidity of the tea soup, and providing收敛 and antibacterial effects. Thus, they can slightly delay the souring and spoilage of tea, which is the reason behind the saying "tea remains unspoiled overnight even in hot summer."

3. Purple clay teapots keep tea warm for a long time.

Due to the numerous tiny air bubbles within the clay walls, filled with stagnant air—which is a poor conductor of heat—purple clay teapots offer excellent heat retention.

4. Using a purple clay teapot prevents scalding when handling or holding it.

The thermal expansion coefficient of purple clay is slightly higher than that of porcelain, and since it is unglazed, there is no stress issue between the body and glaze. After firing, purple clay teapots contain minimal glassy material, giving them sufficient ability to withstand sudden temperature changes and providing slow heat conduction. They excel in resisting thermal shock; even after being boiled at high temperatures over 100°C and then rapidly placed into sub-zero ice, they will not crack. Therefore, when brewing tea with a purple clay teapot, handling and holding it does not burn the hands. In the cold of winter, there is no worry about cracking when using boiling water to brew tea, and it can even be placed on a gentle flame for simmering without the risk of breaking.
