I am trying to read the seal script on the base of a porcelain piece. I am not sure if it is from China or from Japan.
- From right to left, up to down:
Made during the Jiajing era of Great Ming
大明is the official name of the Ming dynasty.
嘉靖年refers to the Jiajing era (1521–67).
製is a verb meaning 'to make', here it is passive. So assuming this not being a counterfeit, it is from China.
An old character for
朙(seen here), which is frequently adopted in seal scripts.
