This tea bowl is made of red clay and coated with sand glaze. White pine needles are shown on the body. The acute angle line of the needle gives us a sharp impression. It has a seal of Raku inside the foot. There is also a note on the box containing the tea bowl which reads "By Nonkau, 3rd Raku". Nonkau is another name of D?nyu (1599-1656), the 3rd head of the Raku family, who was well known as an expert potter.
