Unknown Cornish? Pottery

Hello people,

I wonder please if anyone would be good enough to have a stab at IDing this pottery for me. My Mum bought this back in the early 70s from Cornwall or Devon I think. I have been told previously that it might be Mousehole, as the marking on the back looks like an M, but I don't think it is Mousehole as that make has a very distinctive mark that looks like a mouse peering out of it's hole and this does not have that mark.

It is a dark brown almost fat lava style design and has a marking that looks like a double M on the reverse. I have a near complete coffee set of this but sadly a few cups and saucers got broken over the years and I would dearly like to replace them to get a full set again.

The clay and glaze colour points to European imo. The closest I can find for the mark is Jan Burgess’ Mill Pottery but not her style of pot

Ah OK that is interesting, because it was bought in Cornwall, I'd always assumed that it was from a local studio, but maybe she bought it from a shop that had it imported (she has passed away now so I can't ask her), I will check out Jan Burgess thanks for your help.

Wow, you are right Jan Burgess mark is very close to what I have, not exactly the same but surely it has to be hers? Maybe it was an early work? before she changed her marking slightly?

Although Jan’s Mark looks like just a squiggle it is very consistent and spells Mill. Unfortunately yours is more like an MI

Yes you are right, the more I look at them both the more they look too different. Maybe it's a fake!
