紫砂壶，岁月的见证者，它们在茶友的手中流转，器身逐渐变得光润可爱，如同老朋友般温馨。明代文人闻龙在《茶笺》中赞美道：“摩掌宝爱，不啻掌珠。用之既久，外类紫玉，内如碧云。”这不仅说明了紫砂壶越用越好，而且强调了它内外皆宜的特性，但为何“一壶不事二茶”呢？
答案 lies in the unique characteristics of purple sand teapots. The material used to make them, a mixture of stone, iron ore, mica and clay, creates a complex structure with two types of pores: chain-like pores formed by the connection between different minerals and closed pores within small clay particles on the surface.
These dual-pore structures allow for the release of steam but not water, which is why tea leaves can be stored inside without causing any harm. However, if multiple types of tea are brewed consecutively in the same pot, the flavors will mix and contaminate each other.
To preserve the original flavor and aroma of each type of tea, it's best to use one teapot for each type. This not only ensures that each cup tastes its best but also prevents contamination from occurring. Furthermore, regular cleaning and maintenance are crucial to keep your teapot in good condition.
In conclusion, while it may seem restrictive to only use one teapot per type of tea at first glance, this practice allows you to fully appreciate the unique qualities and flavors associated with each variety. It's all about respecting tradition while finding joy in every sip!
