Thank you, both.....great links.
I'm not a collector or a connoiseur (connoiseuse?), just buying some bits and pieces for the house. I like to buy French because, after all, that's why I came to live here, just to steep myself in the language and culture.
I am quite pleased that I have more or less guessed the differences as per Clair's link.
As many pieces I have looked at are marked "Saraguemines", I googled that and have been very entertained and informed.
The bits that I am negotiating to buy are from the "Digoin" period, so I am trying to pin down the exact time when these would have been manufactured. At the rate of research, I shall soon be an "expert", never fear!
Apprendre une langue, c'est faire un voyage différent chaque jour.
