The base of this ceramic bowl from the Northern Song Dynasty utilizes a black glaze. It features a pie mouth, an arc surface, and an abdomen that gradually closes downwards. A distinctive white trim runs along the mouth of the bowl. The inner wall exhibits a glossy black luster, while the bottom of the outer wall resembles a white peony. Seemingly intentional, yet ostensibly unintentional, it is filled with a simple elegance. The black base supplemented with white enables the bowl to exude Zen sensations. The scattered and mottled traces along the bottom brim with the trials of age.
