This is a Bizen ware teacup with a pattern called "hidasuki." The coarse texture, colors, and patterns produced by the kiln's flames are a remarkable example of Bizen Ware, "the art of clay and fire."

The "hidasuki" pattern is created when the work is wrapped in straw, placed in a kiln with a cover called a "saya," and fired in a location away from direct heat. It becomes light brown in color throughout, with scarlet areas where the straw is wrapped. This contrast between vivid colors makes it very popular. Each firing results in a different pattern, making each piece a unique work of art.
