Southern Song Dynasty Guan ware Celadon Bowl with Rivet and Three legs

A celadon bowl made in the Southern Song Dynasty Guan ware.
It has a short, barrel-shaped body with a slightly rounded bulge, and its mouth narrows inward.
The top and bottom are bordered in a band shape, and along the band are 12 stud decorations on the top and bottom.
The shape of the three legs on the bottom that curve outward is the shape of the legs at the time, and to prevent the legs from crushing, needle supports were attached and fired to leave marks.
These barrel-shaped, drum-nail, and three-legged shapes are often seen in the Guan wares and Longquan wares of the Southern Song Dynasty.
The celadon glaze applied throughout has a clean color, and as a Southern Song Guan ware, it has fine incisions and a moist luster.
The slightly milky glaze tone and the five small needle marks left on the bottom were created under the influence of the Ru ware.
The thin glaze and thick pottery are a type of Southern Song official kiln.

There is no conspicuous flaws.It is in good condition with a moist luster overall.
