History

It made crocks, jugs, cream pots, bowls and pitchers. The pottery continued under later Cowden family names after the partnership stamp went out of use.

Dating clues

  • Doc's Crocks, citing Phil Schaltenbrand's 'Big Ware Turners', dates the partnership stamp to 1863–1880.

Look-alikes and reproductions

  • Other Harrisburg stamps such as WM. MOYER, J. YOUNG & CO. and T.H. WILLSON & CO.

Where sources disagree: CowdenAndWilcox.com says the pottery ran 1861–1923 under various names; Doc's Crocks dates the Cowden & Wilcox stamp to 1863–1880; search summaries also mention a Cowden, Wilcox & Co. period (1867–1873) that we could not confirm on an opened page.

Marks help identify a maker and a date range, but they can’t prove a piece is genuine. Reproductions and later reissues can carry old marks. This entry isn’t an appraisal.
