It wares are not to be confused with earlier wares marked "Della Robbia" produced by Charles Canning in Tamworth. These were often smaller items in more conventional Victorian taste, with painting, often floral, sometimes in overglaze enamel, rather than the coloured glazes used vin Birkenhead. In the early 20th century, Roseville pottery, an American pottery company used "Della Robbia" as a brand for wares (now very expensive) designed by Frederick Hurten Rhead, who emigrated from England in 1902. It has been said that these pieces owed more to Birkenhead than Florence. The Birkenhead factory also marked its wares "Della Robbia", but also used an incised sailing ship as a mark (see gallery).
