This technique of relief ornament, achieved by pushing out the clay by hand from the inside, usually appears on undecorated wares, such as mugs, tankards and posset pots in the third quarter of the 17th century. Among this class of rare survivals there are at least four pieces with painted decoration, as outlined by Michael Archer, Delftware in the Fitzwilliam Museum, London, 2013, p. 163: an initialled and dated mug (1653) from the Longridge Collection; a posset pot and cover dated 1651; a porringer with a portrait of Charles I, dated 1660; and another porringer with a couple, dated 1672. The author also mentions that fragments of undecorated mugs with similar embossed decoration were excavated on the Rotherhithe and Pickleherring sites. A slightly larger tankard with a rope twist handle is also illustrated ibid., cat. no. C. 8, p. 163. A white mug of this form, from the Longridge Collection, is illustrated by Leslie B. Grigsby, The Longridge Collection of the English Slipware and Delftware, London, 2000, Vol. 2, cat. no. D. 236, pp. 262-263 and was sold at Christie's New York, January 24, 2011, lot 28.
