Brief introduction of glazed dish in Song Ruyao

Height 3cm, caliber 17. 1cm, foot diameter 9. 1cm.

The disc is curled, with shallow arc wall, flat bottom, and the circle foot is curled outward. Azure glaze is applied inside and outside the whole body, and the glaze surface is broken with fine chips. Because of "foot-binding", there are three tiny Zhi Ding marks on the outsole.

The enamel of this kind of Ru kiln celadon plate is bright and moist, and the texture is as soft as silk.

Although the celadon of Ru kiln in Song Dynasty has different shades, it can't be separated from the basic tone of "pale azure". This moderate warm and cold tone, with its elegance and refinement, adapted to the "light and subtle" aesthetic taste advocated by the upper class in the Northern Song Dynasty, and made Ru Ci the first porcelain in the Song Dynasty, which has always been favored by the court.

Ru Ci's fetal quality is delicate, like the color of burnt incense ashes, commonly known as "incense ashes". The uniqueness of Ru Ci lies in its beautiful glaze color, jade-like glaze color and jade-like texture. Hui Zhou, a native of Southern Song Dynasty, wrote in Qingbo magazine that "burning is forbidden in Ruyao Palace, and agate is used as glaze". Because Ru Ci's tribute is glazed with agate, it forms a special color. When these objects are seen in the sun, the flesh red is faintly visible. The surface of the device is densely covered with fine scales, which is more unique and unique. The agate crystals around the bubbles in the glaze form starlight, which is as rare as the morning star and has the elegant and pure style of precious light. Ru Ci's firing method is also very unique. It adopts the method of full glaze and matching firing, and the Zhi Ding trace of firing is small and regular, so it is said that "sesame seeds earn nails and glazes". For a long time, experts and authorities in archaeology and collection circles have summed up the main features of Ruyao porcelain in one sentence, namely, "Blue as the sky, jade-like surface, crab claw pattern, rare morning stars, sesame satisfied with nail glaze". These glaze characteristics of Ruyao porcelain are not only recorded in literature, but also confirmed by unearthed objects, which is the key to identify Ru Ci.
