Hi all, my house was built in 1756, but the extension is only 1960s and it's sinking.... The builders came today to dig 'experimental trenches'

and found all sorts of pottery bits and stone. I love this piece, I'm thinking 17thC, is that about right? I know the area was a bakers and tanners in the 1640s. Any thoughts gladly received. Platter? Bowl? What was the design likely to be?
