part she pledges herself not to publish the work, nor permit the work to be published, at a lower price than that at which it is now offered to the subscribers.” The work extends to 86 pages, and contains 136 processes connected with potting, enamels, and glass-staining. The receipts are evidently the compilation of a greatly experienced and very intelligent potter.

Timothy and John Lockett; the manufacture at that time being principally salt-glazed ware. About 1809 the premises were purchased by Joseph Machin and Jacob Baggaley, and carried on by them for the making of china and ordinary earthenware. In 1831 Mr. Machin died and was succeeded by his son Mr. William Machin and partners. The works next passed into the hands of Mr. Richard Daniel, and next to Mr. Thomas Edwards. In 1850 they were purchased by Messrs. T. and R. Boote, who still occupy and work them. [Illustration: Fig. 371.] [Illustration: Figs. 372 to 374.] In 1843 Messrs. Boote took out a patent for “Certain improvements in pottery and mosaic work.” These consist in producing “coloured designs on grounds of different colours, as black on white or white on black. First, the designs are made from a mould, as in figuring, and laid on the moulds for making the ware; the ground colour is then put on. Second, the design, cut in paper, parchment, &c., is laid in the moulds and the halves fastened together, the colour to form the ground is poured in, after which the paper, &c., are removed and other colour poured in to fill its place. Third, producing different coloured raised surfaces. The figures in low relief in the inside of the moulds are filled with a composition, the halves of the moulds fastened together, and the slip poured in to form a thin coating, which was then supplemented with an inner lining of a cheaper material to form a substratum, thus producing mosaic and other elaborate designs. In this process the excess of liquid is withdrawn when the necessary thickness is attained. [Illustration: Fig. 375.]
