Are Yixing teapots fired?

Yixing Teapot is fired under the condition of high oxygen and high temperature, generally using flat firework contact, and the firing temperature is between 1100-1300℃. The water absorption rate of the finished product is greater than 2%. The roasting temperature range of purple sand mud is also wide, from 1190℃ to 1270℃, which is another reason why purple sand products do not leak and do not age, and the more they are used, the more shiny and smooth.
