These are Longquan Celadon dishes from the Southern Song dynasty 1127-1279 AD. I bought them together, and it is interesting to see the slight differences in glaze quality. One is 3,6 cm high and 12,2 cm across, and has the best glaze, but damage to the rim. The other one is 3,5 cm high, and 12,4 cm across, the glaze is slightly less deep in color, and more pitted. They are both quite heavy potted.
They both have a lotus decoration on the bottom, and raised twin fish decoration on top.
Celadon wares are broadly described as ; wares having a grayish or brownish body, covered with an olive or grayish green toned glaze. The wares are high fired porcelanous stoneware with a feldspatic glaze. The Celadon body contains kaolin, quartz and feldspar, the glaze feldspar, lime or wood ash, and silica.
Longquan ware is a southern ware, made from the Song dynasty onward. The kilns stood in Chekiang,North Fukien and Ch’u-chou as market centre. The wares were fired between 1180 ̊ C- and 1280 ̊C.
These dishes were probably wedding gifts.
