Hampshire Pottery Marks

Started in Keene, New Hampshire, Hampshire Pottery was started by James Scholly Taft and his uncle James Burnap in 1871, initially making hanging vases, flowerpots, mugs, pitchers, and other earthenware, they eventually shifted to decorative art pottery. Cadmon Robertson joined the pottery in 1904 and was soon made superintendent.  A chemist, he was responsible for over 900 glaze formulas including a variety of greens, gray, brown, yellow, and most notably a two-tone blue called peacock. Taft sold the pottery to George Morton in 1916 and it was closed in 1923. Pieces with the conjoined M in an O were designed by Robertson and marked as a tribute to his wife Emoretta.
