 The general public drank tea out of wooden bowls at fairs and markets, and the upper classes made a guessing game with the drink.It was not until a tea master by the name of Murata Juko wrote a letter discussing the disciples of the tea ceremony that Shigaraki wares were produced for the specific ceremony.Influenced by Zen Buddhist traditions, Juko reestablished that the tea ceremony should reflect the concept of wabi-suki, the belief of emphasizing simplicity, humility, and intense appreciation of the immediate experience.
