A qingbai glazed ceramic ewer, China, Song dynasty, 16 cm high (small restoration) 

Thermoluminescence test, 23rd May 2005, certifying that the vase was made during the Song dynasty

Some firing imperfections
Presence of two extraction holes to the base rim (interior side) that were taken as a sample for the thermoluminescence analysis 
Restorations: the tip of the spout has been grazed. Two points of glaze were added to limit any successive damage. These two points of glaze are more yellow in colour and crackled 
The tip of the spout slightly curves to the right (when looking at the ewer from the back)
Presence of some areas with a creamy white colour material to the base and the base rim 
A small area near and to the base rim has some unglazed parts. Visible finger print trace to the body near this area. Possible restorations in this area. 
The lower end of the handle is not symmetrical, and slightly curves to the right (when looking at the ewer from the back). The body of the handle also slightly curves to the right
The lower end of the spout is not symmetrical, and slightly curves to the left (when looking at the ewer from the front) 
The decorations near the spout and the handle, as well as the small handles, are not symmetrical 
The ewer seems to be made in two parts: visible joint between the neck and the body when looking inside the ewer
