Five kinds of clay are here used, viz., _Barclay_, which is procured from Stanedge, near Wingerworth. This clay is used to make the arches which are technically called “Bars,” and two of them form nearly a semicircle that spans from side to side of the ovens and whereon the pots are placed. _Setting-clay_ is a clay that is found on the peat-moss, near Stanedge, and is quite of a sandy nature: it acquires the name from its being rolled by the hands into “nobs” and placed upon the “Bars” to “set” the pots upon; unless this was used, the pots would have to be broken to get them off the “Bars.” The _Lidd-clay_ (what is commonly called Fire-clay) is used in the lower parts of the “Ovens” or “Kilns,” because of its being stronger to resist the fire; this clay is procured from Loads, near Holymoorside, about two miles from Brampton. The next clay is the _Brampton-clay_ which is burnt in the upper portion of the “Ovens,” because it will not stand the amount of fire that the Lidd-clay will, although it is of a much closer body, and, when glazed, will resist the action of any acids. _Mixed-clay_ is burnt in the middle portion of the “Ovens;” it is, as its name implies, a mixture of the Brampton and Lidd-clay, of each about equal portions to suit the fire or heat in that portion of the ovens. At these works spirit bottles of a similar character to the one engraved on Fig. 105 were made. One was a representation of Lord Brougham, with the words, “The true Spirit of Reform.” Among the marks used by this firm are-- ESTABLISHED 1826 J. OLDFIELD & CO.

[Illustration: Figs. 99 to 102.] The _Walton Pottery_ was built by William Briddon, the grandfather of the present proprietor, in 1790, and at his death was continued by his son, William Briddon. This gentleman died in 1848, and was succeeded by his son, William Briddon, the present proprietor. It has consequently, from the first to the present moment, been carried on by three generations of William Briddons. The goods made are brown ware and stoneware in all their varieties. In these are produced stew, souse, turtle, beef, and butter pots; jugs of every variety; preserve and pickle jars; pancheons, bowls, and cullenders; porringers and patty-pans; bottles of every conceivable size and shape; filters; spirit-barrels and kegs; foot-bottles and carriage-warmers; tea and coffee-pots; twisted and grotesque pipes, and many other articles. In quality they are much the same as those of other Brampton manufactories.
