Iron-red- gold-ring-mouth cup
This cup is about 9cm in diameter, about 5.5cm in height.
This glaze is similar to the Tianmu glaze in the Song Dynasty which is said to have been lost for more than 700 years. truth be told, I do not know the history of how or when it was re-discovered… But as we all know, the research that the Chinese have put into learning about old glazes is absolutely incredible.
