The productions of these works may be said to comprise most of the useful as well as ornamental purposes to which stone can be applied. In the ornamental departments, vases of admirable design and of great variety, fountains, tazzas (in these three departments some two hundred different designs are produced), terminals, flower-boxes, flower-pots, tree-pots, garden edgings, &c. Figures and busts are also produced. In the more useful architectural departments, chimney-pieces, balustrades, chimney-shafts and tops, window-heads, vases, plinths, capitals, and many other articles are made, as well as memorial crosses, gravestones, cemetery numbers and labels, and other mortuary articles, of such excellent design and finish as to take the place of real stone, at a great reduction of cost. Another speciality of the productions of these works is the manufacture of grindstones and scythe-stones. These are said to preserve their cutting edges better than stones dressed in the ordinary way. Filters, too, for reservoirs, are made extensively, and have the reputation of being the most effective of any introduced. Pavement tiles, both red, white, grey, and other colours, and also inlaid in different patterns, are made. These, among other places, have been adopted on the new Albert Bridge, at Chelsea, with good effect, and are giving entire satisfaction, on account of their great hardness, strength, and non-liability to become slippery. [Illustration: Fig. 372.] [Illustration: Fig. 373.] Another admirable and important element of Mr. Ransome’s inventions is the applying of the silicate of lime to the preservation of stone. The sculpture on St. George’s Hall, Liverpool, the Custom House at Greenock, Trinity College, Dublin, and many other public buildings, have been successfully treated with this solution, which hardens and renders the surface indestructible by time or weather. The trade mark of the company, which is the only mark used in this manufactory, is a winged genius grinding an arrow, from an antique gem at Rome. It is shown on Fig. 373. The works are under the personal superintendence of Mr. A. Pye-Smith, with Mr. Frederick Ransome as consulting chemist; Mr. Bessemer is the chairman. DEPTFORD. In the seventeenth century a pottery existed here, where were manufactured melting-pots, “the best in the world, especially for founders.” These were in great repute, and gradually superseded those imported from Holland, Germany, and Denmark. MERTON (see “Aldgate”). HOUNSLOW. About 1830 the manufacture of earthenware (commenced by Joseph Shore and carried on after his death by his son and grandson Richard and William Goulding) at Isleworth was removed to Hounslow, but died out in the course of a year or two, and has not been renewed.
