Then we went mud-larking. That is, of course, the entirely professional, technical name for the activity. The banks of the Thames are home to tons of interesting finds, including tons of pottery fragments from even a few centuries ago.

Today you can distinguish a piece of pottery’s age by the color of its glaze. Most recent is red, then blue, and then green.
