The seal script translation thread

[Tobias]

I bought this and found the following seal in the bottom of the pot:

I also found three of the characters in bottom of the lid so I'm guessing the "top right" is the name of the maker and "bottom right" + "top left" is his family name?

I can't read Chinese so I haven't had much luck in deciphering any of the characters, except for the the bottom right which looks like zheng 正 inside a (house?).

Are there any experts here who can give any more information?

许定华，Xu Ding Hua.
I have no idea who he is though. There are too many Yixing professionals.

[Tobias]

Great, thanks!
I guess it's just means "made by" or something similar but could you tell me what the fourth character is?

It's nice to have a professional translator on the forum.

[MarshalN]

Yeah it means made

Tobias, in fact, I am very amateur in recognizing those chop characters. There are many styles of them and they often make me feel illiterate So far I only have luck with probably 60-70% of the chops I've seen.

[Tobias]

Well, you nailed 75% this time.

Thanks again.
