Old Ceramic Bowl ID / Date help

Hello, this piece seems really rather old - there's no makers mark and the glaze is somewhat iridescent underneath. Any ideas of maker, origin or era? Thank you :)

That looks to have some real age to it, probably belongs in a museum.

I just picked it up at a charity shop in Bath, the lady there pulled it out the back for me and said it had been donated from a house on the Royal Crescent so could be something interesting!

I would assume it was pretty fancy tableware in its day & not for the commoner

It probably feels put out in my home then
Hopefully, I can find out some more about it. Thinking it's European?

My feeling is it’s traditional European cook ware; maybe 19thC.

Looking at that fryable rim i wonder if it is tin glazed

Do you have any tips on how to tell if it's a tin glaze? I can see that it's quite a thin glaze. Also, it's a relatively lightweight piece. Added some more pics...

Tin glaze is the opaque white coloured glaze used over darker earthenware clay so it can be decorated. Alternatively it might be a thin layer of slip made out of a light coloured liquid clay
