Often, friends mention various issues such as cracked Teapots or detached bottoms, and these problems become more frequent during the winter months.

In winter, the issue of “shock cracking” in purple clay teapots is familiar to many. Zhu-ni (vermilion) clay teapots, in particular, are prone to this problem. When boiling water is poured over them, they can crack with a snap due to the unique properties of their clay, which has a high density and sounds crisp like porcelain when tapped. When suddenly exposed to high temperatures, the Teapot may not withstand the thermal shock and crack. To avoid shock cracking, it's important to warm up the teapot gradually by preheating it before brewing Tea.

Behind instances of shock cracking, there might be pre-existing damage that went unnoticed. When hot water is poured over the teapot, any hidden flaws can quickly expand, leading to cracking. It's advisable to carefully inspect a new teapot for any defects before using it, which can prevent many potential issues.

Purple clay teapots are made of purple clay and are susceptible to damage from knocks and bumps, which can leave unseen injuries. These injuries may not be immediately apparent but can manifest over time with regular use.

Another scenario often overlooked is when a teapot has been unused for a long time and left to dry out. In this state, the clay becomes very porous. Before using such a teapot, it should be cleaned with water and then warmed up with lukewarm water to adjust to the temperature. Pouring boiling water directly onto a cold and dry teapot can cause it to crack due to thermal shock.

During the winter, because of the low temperatures, purple clay teapots require extra care. Warming the teapot with lukewarm water before use is essential for optimal enjoyment of your tea.
