In the mid-1970s, Pat and Sharon Hart of Chatham, New Jersey, founded Hartstone Pottery.
By 1983, they relocated manufacturing to Zanesville. Their business had grown from the Original Ceramic Cookie Mold Company, which produced cookie and shortbread molds sold in antique stores nationwide, into dinnerware and pottery accessories.
Looking to expand, they turned to Ohio, long considered a heartland of the American pottery industry, and found this building to be an ideal home for Hartstone.
Hartstone Pottery operated successfully here for about a decade before the Harts sold the business to Carlisle Home Products. The business continued for approximately another decade before the factory closed in November 2004.
