The Philadelphia Standard: Joseph Wilson and the Market for Colonial Red Earthenware

Another subject that will be included in my forthcoming two-volume, tenth book is when, in 1767, the Massachusetts and Providence, Rhode Island potter Joseph Wilson published an advertisement that has become a key piece of evidence for historians tracking the prestige of Philadelphia red earthenware in the American colonial market. In his notice, Wilson claimed he produced "Earthen Ware at a cheap Rate, made in the best Manner and glazed in the Same Way as Practiced in Philadelphia." 

This direct reference highlights Philadelphia as the gold standard for high-quality, vibrant lead-glazed pottery during the eighteenth century, a status that forced regional potters from New York to Virginia to market their wares as "Philadelphia-style" to attract customers.

The book will show some types of red earthenware manufactured in Philadelphia from a similar context as Wilson's 1767 advertisement. Philadelphia’s red earthenware was distinguished by its sophisticated craftsmanship and decorative flair, often featuring slip-decoration or sgraffito. These techniques involved using a contrasting liquid clay (slip) to paint designs or scratching through a layer of slip to reveal the reddish body beneath. Wilson likely aimed to replicate some of these vibrant aesthetics and glazes, which were often influenced by a mix of English and Germanic traditions.
