A perfect pouring Gong Dao Bei with a shiny lustre and craquelure glaze which will naturally create an eggshell pattern as it stains with tea over years.
The material for this Gong Dao Bei is another Song Dynasty style porcelain fired traditionally in the Ge Kiln. It is similar but different to Ru Yao made historically from the Ru kiln.
The Ge Yao porcelain has a bluer and glassier glaze.

This is a great-sized pitcher to match your fine Gong Fu setups with a capacity of 140ml.
