A studio made ceramic tea bowl (Chawan) with a slightly irregular form and exceptional surface glaze by American potter Warren Mackenzie (1924-2018). Reminiscent of a monk's begging bowl, the stoneware was covered in an orange and white Shino ware glaze, which showcases a characteristic texture full of tiny pinholes and resembles orange rind. One side of the bowl is further splashed with a grey-greenish ash-induced glaze that appears random. The glazed surface shows highly irregular textures with exposed kiln characters such as small indentations and protrusions, occurred during the firing process. A piece that fully embracing the concept of Wabi-Sabi. The chawan is marked with M close to the base rim as shown. Warren MacKenzie was a student of Bernard Leach and Shoji Hamada, the British and Japanese potters who were masters of Mingei (folk art) pottery. Mackinzie is credited with bringing the functional Mingei tradition to the United States and spreading it through his own art and mentorship during his long tenure at the University of Minnesota.
