Genuine Purple-Clay Fair Cup is used for containing tea soup, which looks like a opening tea pot without handle in shape. It is very demanding to make tea and the tea soup's quality can be greatly different due to a few seconds and dozens of seconds. The flavor of the tea soup poured out firstly and tea soup poured out lastly is totally different even it just takes a dozen second for the whole process. To avoid making the tea blocky, you can pour the whole tea soup into fair cup to precipitate tea grounds, and then spare it to tea cups. Nowadays, stainless steel strainers also are commonly used to put over the fair cup to filter tea grounds, which is not the perfect method I think. Because stainless steel is somewhat peculiar smell. As for the second-made tea for smelling doesn't need strainer.
