[Sky Blue Glazed Grape Pattern Ten Ridge Bowl]

Sky Blue Glazed Grape Pattern Ten Ridge Bowl, Qing Yongzheng, 11.5 cm high, 25.2 cm caliber, 14.7 cm foot diameter
The bowl is square, open, with round lips, oblique walls, lower abdomen folded and connected with the flat bottom, and the foot is circled, and the sole of the foot is smooth and convex, like the back of a loach. The whole body is painted with sky blue glaze, and the 10 outer walls are painted with underglaze red grape string patterns. The blue and white book “made in Yongzheng of the Qing Dynasty” on the outsole has three lines and six characters
The underglaze red appeared in the Yuan Dynasty. Due to the limited technical conditions at that time, the stability of the color can not be controlled, so there are not many products with pure color. By the Yongzheng period of the Qing Dynasty, the firing technique of underglaze red had been fully mastered, so the color of underglaze red could be controlled at will. This bowl is set off by the dense and pure sky blue glaze, and painted with the water sprinkling grapes in the underglaze red. The grains are full and tender, and the sky blue and purple red set off each other, each of which is perfect.
