Reading the lines on a celadon bowl

The Palace Museum’s Song-dynasty Yaozhou bowl is small: 5.1 centimetres high, with a mouth 13.2 centimetres across. Its catalogue gives us a useful close reading. One chrysanthemum at the centre of the inner base was made by moulding; radial lines on the inner and outer walls were cut to suggest petals. A stamped flower at the centre meets carved lines around it on this single vessel.

Its flared mouth opens over a deep, curved wall, then narrows to a small ring foot. The profile draws the eye inward, toward the flower at the bottom. Start at the centre, where the chrysanthemum is compact and complete. A patterned mould presses a motif into clay that is still workable. Repeated stamped marks carry the tool’s rhythm. The surrounding petal lines behave differently: each travels outward, and the cut changes the surface’s height. Look for the physical action: pressed pattern or incised groove.

Stamped decoration appeared in Yaozhou ware after carving was already established. The Palace Museum dates its emergence to the middle Northern Song and describes it as mature by the dynasty’s later years. The two techniques meet on this bowl in a particularly clear way: a compact flower pressed into the centre, with lines cut outward around it.

A shallow groove has a near edge and a far edge. When light moves across the bowl, one side catches brightness while the other falls into shade. The carved lines look deeper or sharper as the viewing angle changes. A stamped motif casts its own small shadows, while the repeated edges give the pattern a steady rhythm.

The Palace Museum records a greenish-yellow glaze on this bowl and describes its design as combining a recognizable chrysanthemum with abstract petals. Glaze covers the relief, so the pattern appears through a reflective surface. Recesses can look darker; a raised ridge may catch a brighter line. “Celadon” names a family of glazed ceramics, with shades that shift across objects and light.

A second bowl offers a useful comparison. The National Museum of Korea’s Song Yaozhou bowl is 4.7 centimetres high, with a mouth 14.9 centimetres across. It has a different profile and a scrolling chrysanthemum on its inner base. Its record notes a circular incised feature underneath and glaze scraping near the foot, where the small foot meets the outer base. The foot, base and rim each preserve a potter’s finishing choices; the two bowls show how varied a shared kiln tradition could be.

Look from the centre outward: a flower pressed into the base, radial lines cut around it, greenish glaze catching light along the raised edges. Those marks describe a technique in visible terms. Later copies and related kiln traditions can resemble one another, but this bowl’s combination of moulded flower and carved petals belongs to this object.

Shape, placement, tool marks and glaze build the reading layer by layer. The flower is not a flat emblem; it sits in a shallow landscape of ridges and cuts. Turn the bowl in your mind as the light moves: the carved petals open around a stamped chrysanthemum, and the glaze gives both marks their colour.
