The business of a brickmaker is carried on in the open fields, and its mode of operation may be seen in the neighbourhood of most large towns. The art in almost all its branches is regulated by different acts of parliament: and bricks may be made of pure clay, or of clay mixed, in certain proportions, with sand or ashes.The clay is first moistened and tempered with water, either by the hand, or by means of a machine or mill worked with one or more horses. When it is fit for moulding into bricks, several persons are usually, in the neighbourhood of London, employed upon the business of making a single brick; these are called a gang: they consist of one or two men, a woman, and two children, to each of which is assigned a different department in the occupation. A gang in full work will make many thousand bricks in the course of a single week.The man moulding the clay into the shape of a brick stands under a sort of thatched cover to keep off the sun and the rain: on a board before him are all his implements; the mould into which the clay is put, the clay itself, which is brought to him by another person, a vessel with some water, and a little heap of sand; and near lies the ruler with which he takes off the superfluous clay from the mould.The inside of the box or mould is exactly the shape and size of a brick: the workman throws the clay into this with some violence, having first scattered a little sand about the sides of it; and then scraping off the superfluous clay, he lifts up the mould, and between two small boards conveys it to the barrow which stands near him on the ground. When the barrow is loaded another person comes and wheels away the bricks, and piles them up in an open place to dry. When the pile is made of the proper height, he covers them with long straw, so that they may dry gradually without being exposed to the direct rays of the sun, which would crack them. Heavy rains would also be injurious to them; these are likewise kept off by the straw. As soon as they are sufficiently dry for the purpose they are to be burnt in a kiln. Here great art is required in piling the bricks, so that the fire may circulate through every course and in all directions. Breeze, that is small cinders from sea-coal, is the fuel used in burning bricks, and when once well lighted it will keep burning several days till the bricks are completely finished.
Bricks when finished are of different colours, according to the clay of which they are made, but they must be all of one size; namely, nine inches long, four inches broad, and two inches and a half thick. A duty of 5s.l0d is charged upon every thousand of common bricks; of course this business affords a large revenue to government.The most beautiful white bricks made in this country are manufactured at Woolpit in Suffolk; these are brought by means of water-carriage to all parts of England where great neatness in brick-work is an object.Stourbridge clay and Windsor loam are esteemed the best for making bricks that are required to bear a very intense heat. These are used for coating furnaces, and lining the ovens of glass-houses, where they stand the utmost fury of the fire.A gang of brick-makers will earn a handsome living: sometimes it happens that the whole gang consists of branches of the same family, as the father and mother, and four or five children of different ages; these will earn from two to three guineas a week; but they work many hours, and their labour is very hard.In connection with the trade of brick-making we must notice the manufacture of tiles, which is a sort of thin brick, made use of in the roofs of houses, and also, when something thicker, for the purposes of paving. Those for covering the roofs of houses are of different shapes, according to the uses for which they are intended; these are plain tiles, ridge-tiles, gutter-tiles, pan tiles, &c. They are all made according to certain gauges; and the makers are subject to heavy penalties if their tiles exceed the dimensions fixed on by the several acts of parliament. The kilns in which tiles are burnt are large conical buildings: in these the tiles are piled from the bottom to the top before the fire is lighted. A very large manufactory of this sort is situated near Bagnigge Wells.Dutch clinkers are imported into England for the purpose of paving; they are long narrow bricks of a brimstone colour, very hard and well burnt, so as to be nearly vitrified.Flemish or Dutch tiles, which are glazed and painted, were formerly much used in chimney-jaumbs. Some thirty or forty years ago it was not uncommon to see a complete scripture history, and other curious devices, in a parlour fireplace.
