For anyone interested...
I was looking at a book in the library several months ago about "scanning just about anything".
The author had actually scanned an old ceramic teapot that had a photographic scene on it.
I can't remember the details, sorry.

But if you have the type of scanner with a removable lid, just about anything can be scanned.
I've scanned a framed photograph in mine and it turned out fine. Haven't tried a teapot yet.
