Zisha Teapot is normally referred to Yixing clay teapots. Also called Purple Sand (Chinese: 紫砂; pinyin: zǐshā; ), is made from Yixing clay. This traditional style commonly used to brew tea originated in China, dating back to the 15th century, and is made from clay produced near Yixing in the eastern Chinese province of Jiangsu. (1)
Yixing teapots are intended for puer, black, and oolong teas. They can also be used for green or white teas; however, the heat retention characteristics of Yixing make the brewing process extremely difficult; and in such cases, the water must be heated to no greater than 85 °C (185 °F), before pouring into the teapot. A famous characteristic of Yixing teapots is their ability to absorb trace amounts of brewed tea flavors and minerals into the teapot with each brewing. Over time, these accumulate to give each Yixing teapot its own unique interior coating that flavors and colors future brewings. It is for this reason that soap is not recommended for cleaning Yixing teapots, but instead, fresh distilled water and air drying. Many tea connoisseurs will steep only one type of tea in a particular Yixing teapot so that future brewings of the same type of tea will be optimally enhanced. In contrast, brewing many different types of tea in a Yixing pot is likely to create a coating of mishmashed flavors that muddy the taste of future brewings.
Some Yixing teapots are smaller than their western counterparts as the tea is often brewed using the gongfu style of brewing: shorter steeping durations with smaller amounts of water and smaller teacups (compared to western-style brewing). Traditionally, the tea from the teapot is poured into either a small pitcher, from which it is then poured into a teacup that holds approximately 30 ml or less of liquid, allowing the tea to be quickly and repeatedly ingested before it becomes cooled, or into several teacups for guests.
Q.1. Is Zisha teapot safe for health?
A. Yes Zisha teapot is safe to use! all of them has been cured at high temperature to make it shaped. Yixing teapots are fired for 3 days and 4 nights in the wood kiln. So there is no microorganism in it. Meanwhile, all Zisha teapot is Low thermal conductivity. So the heat transfer very slowly when brewing teas. It's safe to hold.
Q.2. Why are Zisha teapots so expensive?
A. Normally expensive Zisha teapot is made from precious clay. And other factors of the price are age, artist, style, and production methods. The more expensive pots are shaped by hand using wooden and bamboo molds to manipulate the clay into form, while cheaper Yixing pots are produced by slipcasting. Yixing Clay Teapots are always expensive since the limite resource of the special clay.
