17th century English fragment - enough to identify?

This piece was recently found near an early New England settler site. Would be very grateful if any clue to its origin might be offered.

 

Can we see the other side too? There isn't enough there for me, but I know little about really old pottery. Some pottie or other will be along soon.

 

If the left side is cut straight, it appears to be part of a tile.

 

Didn't find anything hopeful online. I think the color of the clay might localize it to some extent, but don't know how to effectively search that. Those broken edges are very clean.

I did find a reference to Virginia clay being imported into England in the 18thC.

Maybe your shard was produced locally?

 

It's tin glazed. That's a very white clay, so possibly a Staffordshire origin or Cornwall. I'd ask the V&A.

 

I'm not entirely sure it's tin-glazed. Some tin-glazed earthenware will craze but usually it's in larger cracking rather than that very fine crazing. Anyway, here is a link to a good diagnostic site in Maryland.

As requested, this second photo shows the reverse side. The dark glaze would seem to indicate a container of some kind.

 

Huh, well the pattern sure reminds me of an old Pfaltzgraff mark. They did make pots with Albany slip glazed interiors. Here is a quick shot of what I mean.

Oho. Well done sis.

 

Sure looks like it! Those pottery pickle crocks were often glazed in a dark color inside. The OP was so sure it was ancient that I didn't even think Pennsylvania mass-production salt glazed.

 

Cape didn't exactly say how they came to think of this as 17th C. I'd think any site that early would be of archaeological interest so perhaps they're involved in a sanctioned dig.

I spent a lot of years volunteering in archaeology and I can say that many times early sites are littered with artifacts from many time periods. A good living site can be quite attractive to many generations of people.

 

Bravissimo!
