"Slag" Quotes from Famous Books



... smoke, blasting furnaces were in full blaze, and light shone from all the windows and apertures. Within hammers and rolling mills were going with such force that the air rang with their clatter and boom. All around the workshops proper were immense coal sheds, great slag heaps, warehouses, wood piles, and tool sheds. Just beyond were long rows of workingmen's homes, pretty villas, schoolhouses, assembly halls, and shops. But there all was quiet and apparently everybody was asleep. The boy did not glance in that direction, but ...
— The Wonderful Adventures of Nils • Selma Lagerlof

... in a few cases by recourse to the older recoveries of Brydges, Haslewood, Park, Collier, and others, bring before the student a mass of brilliant and beautiful matter, often mixed with a good deal of slag and scoriae, but seldom deficient in the true poetical ore. The mere collections of madrigals and songs, actually intended for casual performance at a time when almost every accomplished and well-bred gentleman or lady was expected to oblige the company, ...

... which once caused such devastation, and in which a great commonwealth was well-nigh swallowed up, little is left but slag and cinders. The past was made black and barren with them. Let us disturb ...
— The Rise of the Dutch Republic, 1555-1566 • John Lothrop Motley

... out, and a piece of slag hit me here, where you see that patch. If it wasn't for the patch you'd see something that would make you sick. It was a pain you couldn't tell about . . . it was a couple of days before I knew where I was. And the first thing when I came to my senses ...
— The Second-Story Man • Upton Sinclair

... thoroughfare fronting railroad tracks and a long strip of fenced grass, dotted with newly planted trees, called the "park,"—in a North Dakota town. It was hot. I mean, hot. Down that long thin street the shadows of false-fronted stores lay like blue slag on molten iron. Nothing moved: this particular metropolis-to-be of the Northwest was given over to heat and silence. Yet it wasn't muggy, sea-coast heat that turns bone and muscle into jelly—it was a passion of sun-power, ...

... a new idea," admitted the other, "and one that didn't come to me, I'll own up. A meteor can fall at any old time, day or night, though we only see them shooting after dark sets in. When one of these fragments of fused metal and slag does rush toward the earth and bury itself in the ground, it makes just such a brilliant flash. Some say there is a fearful crash when it strikes. Stranger things have happened, I take it, Bud, than to believe that was a falling meteor ...
— The Boy Scouts of the Flying Squadron • Robert Shaler

... and sand baked, and often almost vitrified into porcelain-jasper. The stratification is gone; the porcellanite has run together into irregular masses, or fallen into them by the burning away of strata beneath; and the cracks in it are often lined with bubbled slag. ...
— At Last • Charles Kingsley

... a white earth, and spreading white branches against the dun and motionless sky. The distant flat shrank in uniform whiteness and low-hanging uniformity of cloud. The very furniture in the room seemed to have shrunk since she saw it before: the slag in the tapestry looked more like a ghost in his ghostly blue-green world; the volumes of polite literature in the bookcase looked more like immovable imitations of books. The bright fire of dry oak-boughs burning on the ...

... together late in the afternoon of the fifth day, when she felt a sudden tug at her heart. Outside the car window, slipping steadily by, were smoke-stained brick factories, and little canals and backwaters soiled with oil and soot, and heaps of slag and scrap iron and clinkers. Then villages swept by—flat, orderly villages with fences enclosing summer gardens. Then factories again—villages—factories—no more of the flat, bare fields: the fields were all ...

... per centum for silicium in the three samples examined. It also was observed that the more manganese the iron contains the less readily the percentage of silicium is diminished; and since manganese is more subject to oxidation than silicium, it is capable to reduce silicic acid of the slag or lining to metal, and thus to augment the amount of silicium in cast iron. The percentage of carbon also suffers diminution by oxidation, which latter process is impeded by presence of manganese, a fact of some importance in ...

... battle, but noticed that many such vessels were flying to and from the front, apparently carrying supplies. The fortress was an immense dome of some glassy, transparent material, partially covered with slag, through which they saw that the central space was occupied by orderly groups of barracks, and that round the circumference were arranged gigantic generators, projectors, and other machinery at whose purposes they could not even guess. From the base of the dome a twenty-mile-wide apron of the same ...

The walls being necessarily constructed thicker than ...

... tireless, unceasing, and tremendous manufacturing industry which distinguishes the Five Towns, and I was left alone in the compartment. The train rumbled on through a landscape of fiery furnaces, and burning slag-heaps, and foul canals reflecting great smoking chimneys, all steeped in the mild sunshine. Could the toil-worn agents of this never-ending and gigantic productiveness find time for love? Perhaps they loved quickly and forgot, like animals. ...

... spontaneous offering. He has at times the primal gift of the poet—ecstasy; but to attain it he often wades through shallow, ill-smelling sewers, scales arid hills, traverses dull drab levels where the slag covers rich ore, or plunges into subterrene pools of nocturnal abominations—veritable regions of the "mother of dead dogs." Probably the sexlessness of Emerson's, Poe's, and Hawthorne's writings sent Whitman to an orgiastic extreme, and the morbid, nasty-nice puritanism that then tainted English ...

... compound of lead,—much as now has come out in the patent toughened glass. Also we initiated mild experiments about an imitation of volcanic forces in melting pounded stone into moulds,—as recently done by Mr. Lindsay Bucknall with slag:—but unluckily we found that the manufacture of basalt was beyond our small furnace power: I fancied that apparently carved pinnacles and gurgoyles might be cast in stone; and though beyond Dr. Kerrison and myself, perhaps it may still be done by the hot-blast melting ...

... a certain September night, when Burns came into his office, alone. The fire in the office fireplace, kept bright until nearly midnight, when his housekeeper had given up waiting for him and gone to bed, had burned to a few smouldering lumps of cannel-slag. A big leather easy-chair, its arms worn with much use, had been pulled into an inviting position before the fireplace, and the night-light by the desk was burning, as usual. All that could be expected had been done by the kind-hearted Cynthia, who comprehended, by signs she knew well and ...
— Red Pepper Burns • Grace S. Richmond

... we urged on our animals over comparatively level ground, in the fallacious hope of seeing the sea that night. The trees became rarer as we advanced and the surface metallic. In spots the path led over ironstone that resembled slag. In other places the soil was ochre-coloured [11]: the cattle lick it, probably on account of the aluminous matter with which it is mixed. Everywhere the surface was burnt up by the sun, and withered from want of rain. Towards ...

... process. The denser materials have been able, on the whole, to gravitate to the center of the structure, and the lighter elements have been able, on the whole, to rise to and float upon the surface very much as the lighter impurities in an iron furnace find their way to the surface and form the slag upon the molten metal. The lighter materials which in general form the surface strata are solid under the conditions of solids known to us in every-day life. The interior is solid or at least acts as a solid, because the materials, though at high temperatures, ...

... this so-called canyon and the water tore from side to side. In one whirl my boat was twice carried around the circle into which I had allowed it to be caught, then shot out on the pounding flood. Soon the slag-like mountains were passed and the country began to spread, first in a high barren land, then with a bottom land running back from the river. The willow bushes changed to willow trees, tall and spindly, crowded in a thicket down to the river's edge. The Chemehuevi ...

... with lime, which in fire increases the heat; while upon the open torta we shall see that lime is used to cool the mass. Litharge (oxide of lead) is added, and the mass is burned until the litharge is decomposed, the lead uniting with the silver and the oxygen entering into the slag, into which the baser metals, or scoria in the ore, have been formed. This is cast out at the bottom of the furnace. The mass of molten lead and silver is drawn off, and placed in a large oven with a rotary bottom, ...

... by adding broken lumps of pure hematite or magnetite iron ore. This causes a violent boiling, which is kept up until the metal becomes soft enough, when it is allowed to stand to let the metal clear from the slag which floats in scum upon the top. The separation of the slag and iron is facilitated by throwing in some lime from time to time. Spiegel, or specular iron, is then added; about 1 per cent. more than in the scrap process. From 20 to 24 cwt. of ore are used in a 5-ton ...

... midst of this fierce welter of sunshine.

But as I would say, in fine, when we had killed the rats, I took ash, slag, and charcoal from the smithy, and burnt earth from the brickyard (I reason that a brickyard belongs to Mars), and rammed it with iron crowbars into the rat-runs and buries, and beneath all the house floors. The Creatures of the Moon hate all that Mars hath used for his own clean ...

... opening; others that it was perhaps a mass of smoke and vapor ejected from a gigantic volcano, or from the vents covering a broad area of volcanic action; others that it might be a vast incandescent slag floating upon the molten globe of the planet and visible through, or above, the enveloping clouds; and others have thought that it could be nothing but a cloud among clouds, differing, for unknown reasons, in composition and cohesion from its surroundings. All of these hypotheses except the last ...

... it was a big straggling sort of suburban town—tramways down the side, dirty little houses lining the street, great chimneys belching (I believe that is the correct term) volumes of black smoke, huge mountains of slag in all directions, rusty brickfields littered with empty tins, old paper, and bits of iron, and other similarly unlovely views. The only thing to be said in favour of this industrial scrap-heap was that the smoke was not quite so sooty as it looked, and things one touched ...

The canal, a portion of the Canal du Nord, was in course of construction at the outbreak of war, and its deep, well-laid bed is one of the engineering wonders of this part of France.

... years of practical experience I have never known a single instance where a lode, on being worked, gave a return according to assay, and I have never known any mine where some of the precious metals could not be found in the tailings or slag.

... have been made by Mr. T.R. Crampton, by Messrs. Whelpley and Storer, and by Mr. G.K.
