J. Phillips, Hylton Pottery, appears on some Sunderland pieces. This firm was established as early as 1765.

Ford is another name in connection with the South Hylton works about 1800.

Dixon, Austin & Co., sometimes with the addition of Sunderland, is found at the beginning of the nineteenth century.

W. S. & Co., with the word Wedgewood (having an additional "e") was the mark used by William Smith & Co., of Stockton-on-Tees, or even "Wedgwood & Co." Against this firm Messrs. Josiah Wedgwood & Sons, of Etruria, obtained in 1848 an injunction to restrain the use of their name.

Another equally confusing mark to collectors is that of a firm near Pontefract, who marked their ware "Wedgwood & Co." sometimes with the word name of the factory, "Ferrybridge," and sometimes "Tomlinson & Co." Their ware is mainly cream ware of an ordinary type.

In regard to the productions of Newcastle and Sunderland these are best known by the familiar mugs and jugs having a nautical flavour, with ships in black transfer decoration, and never without verses appropriate to the clientèle of sailors, for whom they were made. These mugs and jugs are frequently decorated with pink lustre at the rims and in bands around the body. A feature which associates these northern factories with Leeds is the frequent use of a modelled frog crawling up the inside of the vessel, which was intended as a practical joke on the person who was lifting the jug to his lips. These frog mugs were previously made at Leeds, and the one illustrated ([p. 303]) has a frog so affixed in the inside.

The ware, as a whole, is rather crude in its potting and slightly inferior to similar Staffordshire ware, but all these northern factories are now closed, and the quaint doggerel, the queer nautical allusions, and the strain of patriotism found on much of this humble earthenware always appeal strongly to the collector.
