Recently discovered artifacts of colonial America’s artisanal history will be unveiled to the public on Thursday at the New York Ceramics and Glass Fair.

After being found buried in a privy shaft in the Old City district of Philadelphia, over 10 pieces of slipware pottery from the 18th century will displayed in a show called “Buried Treasure: New Discoveries in Philadelphia Slipware from the Collection of the Museum of the American Revolution.”

The ceramics were uncovered during an excavation of the grounds of the new Museum of the American Revolution in Philadelphia. Archaeologists from the Commonwealth Heritage Group recovered almost 85,000 artifacts from the site between 2014 and 2016.
