I am begginer in tea art and I use the gaiwan many time to brew a tea.Some day I use a small clay teapot(maybe Yixing) who I make shu puer.This teapot is very appropiate to authentic yixingteaspot factors.So is not authentic, I think is good to make tea,because is very useful to understand how is gong fu practice in a small teapot(is 120 ml volume).It work very good!And the infusion goes well!
