Nomiyama, I apologise for diverting the conversation. Here's my best available answer. Joanie has sort of pre empted it already.

The pots are stamped and signed when they are leather hard. The master potter may decide at this moment that the pot is of a standard to bear his/her signature.

Unskilled potters also have this choice.

But the job is only half done as kilns are not always stable. Therefore a signature pot from a distinguished master potter may or may not be of extremely high standard.

Cheers
Lindsay
