Glaze Alone: Song Dynasty Ceramics

Song potters argued about glaze the way painters argue about surface. Ru and Guan were court wares, made in small quantities with glazes thick enough to pool and crackle; Yaozhou carved the body and let green gather in the cuts; Jian fired an iron glaze until it crystallised into hare’s fur for tea bowls; qingbai went the other way, so thin and pale that carving shows as relief rather than colour. One tradition mixed two clays and let the body itself be the pattern. None of these wares rely on painted decoration — that work belongs to later porcelain, where cobalt and enamel do the talking. Here the whole object is a decision about thickness, temperature and the behaviour of a single colour.

Ru ware served the Northern Song court for only a few decades before the kilns were lost, and around ninety pieces are thought to survive. The glaze is dense and matte, a pale blue-green that Chinese writers compared to the sky after rain, and the crackle net through it is part of the intended surface rather than a fault.

Guan means official: these were the Southern Song court’s own kilns at Hangzhou. A dark body carries a thick grey-green glaze, and the crackle was often stained so the lines read as a drawing laid over the form.

A rest made so a wet brush could lie across it without touching the desk. The glaze pools where the form rises and thins where it falls away, so the shape is read through the thickness of the glaze rather than through carving.

Tea was whisked to a foam, and Jian bowls were prized because a dark glaze makes the pale froth legible. The streaks called hare’s fur form as iron crystallises in the glaze while it cools in the kiln; the metal band on the rim replaced a chipped edge.

Yaozhou potters carved the pattern into the dried body and let the olive glaze gather in the cuts, so the decoration is drawn by depth of glaze rather than by a second colour. It is a potter’s drawing made with a knife.

Grey-green glaze over a grey body, incised so lightly that the pattern only appears when the bowl is turned against the light. Northern celadons depend on that reserve: nothing is added, and the decoration is barely a change in depth.

Yaozhou’s green comes from the same iron in reduction as the court celadons, but the tone is warmer and the surface glassier. A saucer is the honest test of a glaze: there is no form to hide behind, only the pool of colour inside the rim.

Qingbai, blue-white, is porcelain with a glaze so thin and pale that it reads cool rather than green. The combed scroll underneath shows as a faint relief instead of a colour, so the pattern changes as the light moves across the dish.

A meiping, the plum vase, made to hold a single branch and shaped so the shoulder carries the eye down to a narrow foot. Under a qingbai glaze, carving works by pooling: the incisions fill with glaze and the spray appears without any added pigment.

Two clays, light and dark, kneaded together and cut so the pattern runs through the body rather than sitting on it. The glaze is clear and thin and does nothing except keep the marbling looking wet — one of the few Chinese wares where the decoration is the clay itself.

By the Jin period Yaozhou workshops were moulding decoration rather than carving it, so the peonies repeat exactly across the bowl. That is a different kind of object: faster to make, easier to standardise, and evidence of a workshop thinking about output rather than about one pot.

Longquan celadon travelled further than any other Chinese ware — to Japan, Southeast Asia and the Middle East. The lotus petals are carved so the thick glaze collects at their edges, and the green deepens wherever the surface turns away from the light.
