The Refiner's Test is pointed out to us;—a sort of shovel, with a spout, lined throughout with a material of burnt bones, the only substance which can endure unchanged the heat necessary for testing the metals. Of this material are made the little crucibles that we see in the furnaces, which our conductor admits to be "rather warm." There they are, ranged in rows, so obscured by the mere heat, which confounds every thing in one glow, that their circular rims are only seen by being looked for. Yet, one little orifice, at the back of this furnace, shows that even this heat can be exceeded. That orifice is a point of white heat, revealed from behind. We do not see the metal in the crucibles; but we know that it is simmering there.
One more oven is opened for us—the assay furnace, which is at a white heat. As the smallest quantities of metal serve for the assay, the crucibles are here on the scale of dolls' tea-things. The whole concern of that smallest furnace looks like a pretty toy; but it is a very serious matter—the work it does, and the values it determines.
The metals, which run down to the bottom, in the melting furnaces, are separated (the gold and silver by aquafortis), and cast in moulds, coming out as ingots; or, in fragments, of any shape they may have pleased to run into. Some of the gold fragments are of the cleanest and brightest yellow. Other, no less pure, are dark and brownish. They are for gilding porcelain. Lastly, we see a pretty curiosity. In the counting-house, a little glass chamber is erected upon a counter, with an apparatus of great beauty—a pair of scales, thin and small to the last degree, fastened by spider-like threads to a delicate beam, which is connected with an index, sensitive enough to show the variation of the hundredth part of a grain. The glass walls exclude atmospheric disturbance. Behind the rusty-looking doors were the white glowing crucibles; within the drawers was the yellow gold; and, hidden in its glass house, was the fairy balance.
Now, we will follow some of the gold and silver to a place where skilled hands are ready to work it curiously.
First, however, we may as well mention, in confidence to our readers, that our feelings are now and then wounded by the injustice of the world to the Birmingham manufacturers. We observe with pain, that the very virtues of Birmingham manufacture are made matters of reproach. Because the citizens have at their command extraordinary means of cheap production, and produce cheap goods accordingly, the world jumps to the conclusion that the work must be deceptive and bad. Fine gentlemen and ladies give, in London shops, twice the price for Birmingham jewelry that they would pay, if no middlemen stood, filling their pockets uncommonly fast, between them and the manufacturer; and they admire the solid value and great beauty of the work; but, as soon as they know where the articles were wrought, they undervalue them with the term "Brummagem." In the Great Exhibition there was a certain case of gold-work and jewelry, rich and thorough in material and workmanship. The contents of that case were worth many hundred pounds. A gentleman and lady stopped to admire their contents. The lady was so delighted with them that she supposed they must be French. The gentleman reminded her that they were in the British department. After a while, they observed the label at the top of the case, and instantly retracted their admiration. "Oh!" said the gentleman, pointing to the label, "these are Brummagem ware—shams!" Whatever may have been Brummagem-gold-beating in ancient times, and in days of imperfect art when long wars impeded the education of English taste, it is mere ignorance to keep up the censure in these times. It is merely accepting and retailing vulgar phrases without any inquiry, which is the stupidest form of ignorance. Perhaps some of the prejudice may be removed by a brief account of what a Birmingham manufacture of gold chains is at this day.
Twenty years ago, the making of gold chains occupied a dozen or twenty people in Birmingham. Now, the establishment we are entering, alone, employs probably eight times that number. Formerly, a small master undertook the business in a little back shop: drew out his wire with his own hands; cut the devices himself; soldered the pieces himself; in short, worked under the disadvantage of great waste of time, of effort, and of gold. Into the same shop more and more machinery has been since introduced as it was gradually devised by clever heads. This machinery is made on the spot, and the whole is set to work by steam. Few things in the arts can be more striking than the contrast between the murky chambers where the forging and grinding—the Plutonic processes of machine-making—are going on, and the upper chambers, light and quiet, where the delicate fingers of women and girls are arranging and fastening the cobweb links of the most delicate chain-work. The whole establishment is most picturesque. While in some speculative towns in our island great warehouses and other edifices have sprung up too quickly, and are standing untenanted, a rising manufacture like this cannot find room. In the case before us, more room is preparing. A large steam-engine will soon be at work, and the processes will be more conveniently connected. Mean time, house after house has been absorbed into the concern. There are steps up here, and steps down there; and galleries across courts; and long ranges of low-roofed chambers; and wooden staircases, in yards;—care being taken, however, to preserve in the midst an isolated, well-lighted chamber, where part of the stock is kept, where some high officials abide, and where there are four counters or hatches, where the people present themselves outside, to receive their work. All this has grown out of the original little back-shop.
Below, there is a refinery. It is for the establishment alone; but, just like that we have already described—only on a smaller scale. First, the rolling-mill shows us its powers by a speedy experiment;—it flattens a halfpenny, making it oblong at the first turn, and, by degrees, with the help of some annealing in the furnace, drawing it out into a long ribbon of shining copper, which is rolled up, tied with a wire, and presented to us as a curiosity. Next, we see coils of thick round wire, of a dirty white, which we can hardly believe to be gold. It is gold, however, and is speedily drawn out into wire. Then, there are cutting, and piercing, and snipping machines—all bright and diligent; and the women and girls who work them are bright and diligent too. Here, in this long room, lighted with lattices along the whole range, the machines stand, and the women sit, in a row—quiet, warm, and comfortable. Here we see sheets of soft metal (for solder) cut into strips or squares; here, again, a woman is holding such a strip to a machine, and snipping the metal very fine, into minute shreds, all alike. These are to be laid or stuck on little joins in the chain-work, or clasps, or swivel hinges, where soldering is required. Next, we find a dozen workwomen, each at her machine, pushing snips of gold into grooves, where they are pierced with a pattern, or one or two holes of a pattern, and made to fall into a receiver below. Each may take about a second of time. Farther on, slender gold wire is twisted into links by myriads. At every seat the counter is cut out in a semicircle, whereby room is saved, and the worker has a free use of her arms. Under every such semicircle hangs a leathern pouch, to catch every particle that falls, and to hold the tools. On shelves every where are ranges of steel dies; and larger pieces of the metal, for massive links or for clasps, or for watch-keys and other ornaments, are stamped from these. On the whole, we may say, that in these lower rooms the separate pieces are prepared for being put together elsewhere.
That putting together appears to novices very blinding work; but, we are assured that it becomes so easy, by practice, that the girls could almost do it with their eyes shut. In such a case we should certainly shut ours; for they ache with the mere sight of such poking and picking, and ranging of the white rings—all exactly like one another. They are ranged in a groove of a plate of metal, or on a block of pumice-stone. When pricked into a precise row, they are anointed, at their points of junction, with borax. Each worker has a little saucer of borax, wet, and stirred with a camel-hair pencil. With this pencil she transfers a little of the borax to the flattened point of a sort of bodkin, and then anoints the links where they join. When the whole row is thus treated, she turns on the gas, and, with a small blow-pipe, directs the flame upon the solder. It bubbles and spreads in the heat, and makes the row of links into a chain. There would be no end of describing the loops and hoops, and joints and embossings, which are soldered at these gas-pipes, after being taken up by tiny tweezers, and delicately treated by all manner of little tools. Suffice it, that here every thing is put together, and made ready for the finishing. In the middle of one room is a counter, where is fixed the machine for twisting the chains—with its cog-wheels, and its nippers, whereby it holds one end of a portion of chain, while another is twisted, as the door-handle fixes the schoolboy's twine, while he knots or loops his pattern, or twists his cord. Here, a little girl stands, and winds a plain gold chain into this or that pattern, which depends upon the twisting.
These ornaments of precious metal do not look very ornamental at present; being of the color of dirty soap-suds, and tossed together in heaps on the counters. We are now to see the hue and brightness of the gold brought out. We take up a chain, rather massive, and reminding us of some ornament we have somewhere seen; but it is so rough! and its flakes do not appear to fit upon each other. A man lays it along the length of his left hand, and files it briskly; as he works, the soapy white disappears, the polish comes out, the parts fit together, and it is, presently, one of those flexible, scaly, smooth, glittering chains that we have seen all our lives. Of course, the filings are dropped carefully into a box, to go to the refinery. There is, here, a home-invented and home-made apparatus for polishing and cutting topazes, amethysts, bloodstones and the like, into shield shapes, for seals, watch-keys, and ornaments of various kinds. The strongest man's arm must tire; but steam and steel need no consideration—so there go the wheels and the emery, smoothing and polishing infallibly; with a workman to apply the article, and a boy to drop oil when screw or socket begins to scream. This polishing and filing was such severe work, in the lapidary department, in former days, that the nervous energy of a man's arm was destroyed—a serious grief to both worker and employer. At this day, it is understood that the lapidary is past work at forty, from the contraction of the sinews of the wrist, consequent on the nature of his labor. The period of disablement depends much on the habits of the men; but, sooner or later, it is looked for as a matter of course. Here, the wear and tear is deputed to that which has no nerve. As the proprietor observes, it requires no sympathy.
It may be asked how there comes to be any lapidary department here? Do we never see gold chains the links whereof are studded with turquoises, or garnets, or little specks of emerald? Are there no ruby drops to ladies' necklaces?—no jewelled toys hanging from gentlemen's watch-guards? We see many of these pretty things here; besides cameos for setting.
