The Gong Dao Bei (fairness cup) is a pitcher for serving tea so that everyone receives an equal strength brew in traditional Chinese tea ceremony. If you were to serve direct from a teapot or Gaiwan, the first cup would get a weaker brew than the last cup. The Gong Dao Bei allows you to strain the tea from the teapot or Gaiwan into the pitcher to even out the brew so that everyone gets to taste the same tea.
This ceramic fairness cup was handmade with high quality natural clay in Dehua county, and finished with gilt rust glaze. Due to the high iron oxide content in the glaze, after firing at the high temperature (1310 Celsius), the surface of the fairness cup presents rust color & look. This tea pitcher was designed to be rustic and sturdy, yet good in quality.
