pottery glazed on the outside in shades of aubergine. The glaze is Jun style with iridescent blue hues. On the edges of the shape, the glaze becomes lighter and reveals the color of the paste, which is brown. The interior and the base have a layer of blue glaze, with a slight crackle, which joins the interior. The foot is round and is unglazed on its edge. The shape is rectangular and shows the trigrams in relief around the faces, reminiscent of ancient "Cong" jades and bronzes.Size: 17.50 x 11.80 x 11 cm; Mouth diameter: 10.50 cmProvenance: European private collection.
