'Tea Ware Pictorial' (茶具图赞) is a book by Shenan (审安老人).
It was compiled in 1269, and is the earliest picture book on tea ware used in preparation of Song dynasty tea cake for drinking. Tea during the Song Dynasty was prepared by using the whisking tea method. The green tea was ground into a fine powder and hot water was added then whisked in a bowl with a brush to make tea and foam, this Chinese method of preparing tea spread to Japan and became the way tea is made in Japan today. While in China this method gave way to the brewing tea method, which is the infusion of loose tea.
