This is a Jian ware black-glazed iron-spotted bowl (Tenmoku tea bowl), believed to be from the Song dynasty. The natural iron-spotted pattern on the black glaze is beautiful, and this bowl evokes the strength and quiet charm characteristic of Song dynasty Jian kiln tea bowls. Based on the clay, glaze, and firing atmosphere, I believe it is an authentic piece from the period. This item is recommended not only as a tea utensil but also for appreciation and as a reference for antique art. ■ Size (approx.)
