Gofun is a Japanese traditional “white” color whose component is calcium carbonate made from Itabo oyster. Left and weathered for over 10 to 15 years, shells are grinded to a stone powder with a stone mill. At the same time, they are purified well and made into sheet-shaped by air seasoning. You can mix with general pigments such as sumi ink and vermillion. The quality becomes finer as it goes by Shirayuki(白雪印), Hakuju(白寿印) and Kinpo. Kinpo(金鳳印) is a soft color which is suitable for coating and finishing and Shirayuki(白雪印) is a white color that is suitable for base coating.
*Since it is a sheet-shaped pigment, please make sure to grind well before using.
