This basic Ru style glaze cup from Xiangfu delivers a rich milky Ru Yao finish that crackles over time at an extremely affordable price point. Ru porcelain can be extremely expensive coming out of Taiwanese workshops, but Xiangfu delivers a beautiful color and a graceful take on the swirl cup shape at an accessible price. Over months of use, the crazing will fill in and darken with tea for a beautiful effect.
