Porcelain is more expensive to make one kind of tea per pot, and you need to rest once a month
The porcelain is finer and will not cause tea water to penetrate into the teapot, so you can brew more in one pot Several kinds of tea
Of course, purple sand is better, but if you just drink tea by yourself, you can buy a handful of purple sand to make your most popular tea. The rest can be used in porcelain pots, which are also commonly used in tea shops. There are many porcelain teapots, otherwise how many purple clay teapots would be needed for so many kinds of tea. . The cost is too high, haha. I now use ancient porcelain tureens instead of teapots, and brew the tea in small teacups. I learned this from the tea shop owner. . It saves money.
