Product Specifications Capacity: 70ml Diameter: 8.0cm Height: 4.5cm Material: White Clay & Jun Mineral Glaze Food Safe: Yes Packaging: Premium gift box Following the brief twenty-year firing period of Northern Song Ru ware, Jun ware ascended to the historical stage, swiftly becoming one of the Five Great Kilns of the Song dynasty. The phrase "one color enters the kiln, ten thousand colors emerge" describes the diverse hues naturally formed through kiln transformation during the firing of Jun ware. Jun glaze contains elements such as copper and iron, which interact and permeate the clay body. Fired at 1350°C, this process results in unpredictable, transformative colors. This Jun ware master cup is entirely handmade, featuring carved three-dimensional mountain patterns that convey a sense of majestic, layered peaks. The cup body exhibits a distinctive kiln-transformed coloration known as "rooster-blood red." Originating from the birthplace of Jun ware: Yuzhou, Henan.
