=Cast Iron and Hollow Ware.=--[W. KENRICK, M.P.]--(B. 103.) Since 1866 the increase in the trade is remarkable, and some important improvements have been introduced by which the public has obtained a very superior article, at a price quite as low, if not lower than before. Roughly speaking, the trade has doubled in twenty years. Enamelled iron ware has become better known and more appreciated. Ten firms are now engaged in this manufacture. Messrs. Baldwin, of Stourport, have introduced and patented a new process, whereby they claim the production of a better enamel at a lower price, owing to the use of a single coat. This variety is called mottled enamel ware. Messrs. Kenrick were the first in the trade to introduce a cover stamped out of a single piece of metal without rivet or seam, and this was manufactured under a patent taken out by Mr. Ryland in 1868. Since then the adoption of a solid cover has extended generally throughout the trade. By another patent, the firm fixed the tubular handle to the saucepan by means of a socket in which the tube was securely locked without a rivet. The process of annealing has been improved by a saving of time occupied in the process. Machinery has been introduced into the moulding of hollow-ware, the stamping and finishing of covers, and the dressing of hinges and sash pulleys. The odd work which comprises most small articles of cast iron used by builders’ furnishers, &c., has undergone a great change in appearance, owing to the introduction of a new style of finish from America. A coat of transparent varnish is now applied, the iron being previously polished on those parts in relief, and the result is an appearance somewhat resembling antique bronze. This, together with greater lightness and elegance of design, has given an impetus to the trade, and has led to the introduction of iron where brass was previously used. The favourable conditions of labour described in 1866 still prevail, though it may be added that progress in this direction has at least kept pace with the advance in progress of manufacture, and the greater excellence in the ware produced. The provisions of the Factory Acts have long applied to this industry with beneficial results. The hours of labour have been reduced, and thanks to the Education Act of 1870, the intelligence and docility of the younger operatives are their notable characteristics. What is now wanted is the establishment of Science and Art classes where the principles which underlie processes may be learnt, and the power to add beauty of form to articles of utility may be acquired. When these branches of technical training are added to the course of elementary instruction in our public Schools, all that is needed to secure the prosperity of British industry will have been done.
