We call it the Soba soup cup of Guangdong style that bottom is large and is high.
Pattern drawn on the inner bottom is Sanskrit character.
Inner bottom dents spherically.
That has thickness of 0.39".
And it is small, but is heavy for the thickness.
It has the wet touch in order to wear glaze not to do unglazing.
How is that you use it as substitute of coffee cup, whiskey glass or flowerpot of mini-Bonsai?
