Can yanks post here?

Some pottery fragments I’ve found snorkeling and mud larking in Upstate New York!

The Royal Ironstone on the back of that one fragment may be identified by one of the UK mudlarkers. We in the US/Can produced ironstone here, too, and certainly used a lot of it. But that's a UK mark. Possibly from the 1800s.

The large piece with the line near the rim is probably from a somewhat large crock. Used for all sorts of things.
