Yoon graduated from the Ceramics department at Hong Ik University, Seoul in 1973. The next year he was awarded a grant by the Korean government to study at a kiln in Karatsu on Kyushu, the southernmost island of Japan, where Korean potters first worked in the mid-16th century. Yoon's work harks back to Punch'ong pottery of Korea's 15th and 16th centuries, He shapes his forms from red clay by hand and decorates them with liquid clay, or white slip. While the clay is still wet he may give the form texture from a wood paddle or incise the surface with a nail or knife. Yoon has exhibited frequently, including solo shows at the Kyoto Craft Center Gallery in 1986, the Ho-Am Art Museum (Leeum Samsung Museum of Art), Seoul, in 1998 and the Philadelphia Museum of Art in 2003.
