These scoundrels, doing perfectly ordinary highway department archaeology just like I do, stumbled across one of the best possible archaeological finds: a house that burned down while it was still full of stuff, and then was left alone. The house, near Andover, Connecticut, burned around 1755.
web site, is this white salt-glazed stoneware tea set, probably made around 1750. Note that although the tea set was destroyed by fire while still in use, and then buried in the bottom of a cellar, which was 100 percent excavated, there are still missing pieces. In my experience, there are always missing pieces; I have never found all the pieces of any broken ceramic vessel.
