with a degree of hardness and fineness of texture which render them insusceptible of disintegration. The quality of the stoneware or “Bristol ware” produced at the “London Pottery” is remarkably good, being extremely hard, and covered with an excellent, clear, and firm glaze, not surpassed by any other house. The same remark will apply to the porous ware, which is fine in composition, and possesses to an eminent degree the porous quality so essential in vessels of this description. The terra-cotta goods are of very fine, hard, and durable quality, and of a peculiarly pleasing tone of colour. Their artistic execution is of a high order, and some of the designs--as notably the draped bowl and flower-pots which are engraved on Figs. 340 to 342, and 345, 346. [Illustration: Fig. 340.] [Illustration: Fig. 341.] [Illustration: Fig. 342.] [Illustration: Fig. 343.] [Illustration: Fig. 344.] [Illustration: Fig. 345.] [Illustration: Fig. 346.] Messrs. Stiff & Sons produce a large number of filters of excellent construction and of artistic design. Some of these have Gothic arches, with figures or armorial decorations, and others are decorated with elegant foliage; two of these effective designs are shown on Figs. 343 and 344. These filters have been more than thirty years before the public. The filtering medium consists of alternate layers of charcoal, silica, and another purifying substance, all carefully cleansed, and so arranged as to retain full efficiency for eight or ten years without further cost or trouble. The “Popular” filter--intended for common use among all classes--purifies eight gallons of water per day, and is sold complete and fitted for a mere trifle. The potteries of Messrs. Stiff & Son are among the largest in London. They employ about two hundred hands, and their annual import of raw material, clay, coals, &c., is about 15,000 tons. They have business relations in almost all parts of the world, and their manufactures have been admitted to the principal International Exhibitions; their terra-cotta vases combine excellence of finish with correctness of design, and are sold at very moderate prices. Their stoneware chemical apparatus has a very wide reputation, and their drain-pipes and other sanitary appliances, comprising nearly two-thirds of their business, have an immense sale. It is well to add that at this pottery antique jugs and water-jugs, of excellent design and clever manipulation, are made. The forms are chaste and good, and they have, partly owing to the care in making, and partly to the fineness of the glaze, a pleasanter feel to the hand than others. The carriage and foot warmers, &c., made here are also extremely good in quality and design.
