"Red heat" Quotes from Famous Books
 ... of large diameter or thin wall is to be cut, it is often better not to attempt to break it in the usual way, but to heat a very small globule of glass (1/16 to 1/8 inch diameter) to red heat, and touch it to the scratch. This will usually start the crack around the tube; if it has not proceeded far enough, or has not gone in the desired direction, it may be led along with a hot point of glass. This is put a little beyond the end of the crack, and as the latter grows out toward it, ...

... three different government seals upon the despatches. He then took a long Dutch earthen pipe which was hanging above, broke off the bowl, and put one end of the stem into the fire. When it was of a red heat he took it out, and applying his lips to the cool end, and the hot one close to the sealing-wax, he blew through it, and the heated blast soon dissolved the wax, and the despatches were opened one after another without the slightest difficulty or injury to the paper. He then commenced ...

... in the air is not difficult to explain; it is the heat of friction which so quickly brings them to incandescence. Calculation shows that a body moving through the air at a velocity of about a mile per second will be brought, superficially, to the temperature of "red heat'' by friction with the atmosphere. If its velocity is twenty miles per second the temperature will become thousands of degrees. This is the state of affairs with a meteorite rushing into the earth's atmosphere; ...

... likely that Jupiter is a body very much like our sun, only that the dark portion is too cool to emit much, if any, light. It is doubtful whether Jupiter has anything in the nature of a solid surface. Its interior is in all likelihood a mass of molten matter far above a red heat, which is surrounded by a comparatively cool, yet, to our measure, extremely hot, vapor. The belt-like clouds which surround the planet are due to this vapor combined with the rapid rotation. If there is any solid surface below the atmosphere ...

... The oxidation or burning of the sulphur will provide all the heat necessary to maintain the continuity of the process. The temperature necessary for effecting the elimination of both sulphur and arsenic is not higher than that equivalent to dull red heat; and provided that there is a sufficient mass of ore maintained in the furnace, the potential heat resulting from the oxidation of the sulphur will alone be adequate to provide all that is necessary ...

... of boron trioxide, soot, and oil is heated in a stream of the vapor of carbon bisulphide. M. Sabatier finds that the best results are obtained by employing the method of Wohler and Deville. The reaction between boron and sulphureted hydrogen only commences at red heat, near the temperature of the softening of glass. When, however, the tube containing the boron becomes raised to the temperature, boron sulphide condenses in the portion of the tube adjacent to the ...

If it is adulterated with marl, sand, clay, &c., the ash will be about 60 or 65 per cent, of the weight tested, and be colored with the iron always present in the adulterating ...

Except that the iron floors of their blast ovens were made to revolve while in a state of red heat, all was substantially the same as at the last place. Following the meanderings of the stream, I had been gradually descending from the sharp air of early spring to the more appropriate temperature of the tropics, as I had occasion to notice in looking ...

His piety, or his poetry—not admirable whichever it may be—glows here to a red heat. We are as little disposed perhaps as himself, to stand "shrieking out" over the military severities of this campaign, but if we could bring ourselves to believe that Mr Carlyle is really serious in what he writes, we should say that the most impracticable ...

... gone down behind the pines and a warm mist steamed up from the cooling earth, condensing into heavy dew on the dusty leaves of the plants in the ditch. Above the lowering pines the horizon burned to a deep scarlet, like an inverted brazier at red heat, and one gigantic tree, rising beyond the jagged line of the forest, was silhouetted sharply against the enkindled clouds. Suddenly, from the shadows of the long road, a voice rose plaintively. It was rich and deep and colourific, and it seemed to hover close to the ...

... of these methods and is still largely used. In this method a semi-cylindrical copper plate is heated in a suitable furnace to a bright red heat, the cloths are rapidly passed over it, and the loose fibres thereby burnt off. One great trouble is to keep the plate at one uniform heat over the whole of its surface, some parts will get hotter than others, and it is only by careful attention to the firing of the furnace that this ...

The face of the latter, however, is more than twelve times as large, and it has not the same silvery appearance as the moon, but is rather of a dingy pink hue, like that of her iron when beginning to lose its red heat. As the same part of the moon is always turned to the earth, one half of her surface is perpetually illuminated by a moon ten times as large to the eye as the sun; the other hemisphere is without a moon.

... turning at a right angle when within a couple of feet of the ceiling, proceeded to the chimney at the upper end of the hall. When the thermometer stood much below zero, we were accustomed to raise the stove and part of its pipe to a dull-red heat, which had the effect of partially melting the contents of the water-jugs in our bedrooms, and of partially roasting the knees of our trousers. To keep this stove up to its work was the duty of an Indian youth, whom we styled Salamander, because he ...

Many years ago I prepared my own hard rouge by precipitating ferrous sulphate solution by aqueous ammonia, washing the precipitate, and heating it to a red heat. The product was ground up with water, and washed to get rid of large particles. This answered every purpose, and I could not find that it was in any way inferior to hard rouge as purchased. The same ...

Unfortunately I had forgotten a sulphur-still; and the engineer vainly attempted to extract the ore by luting together two iron mortars, and by heating them to a red heat. The only result was the diffusion of the sulphur crystals in the surrounding gypsum. This discovery gave me abundant trouble; the second search-party was a failure; and it was not till February 18th that I could obtain a satisfactory plan of ...

... free hydrofluoric acid remains in solution. If the quantity of water is greater, the solution may be preserved for some minutes without decomposition. If the liquid is boiled, it decomposes instantly. At a red heat platinic fluoride decomposes into metallic platinum and fluorine, which is evolved in the free state. This reaction can therefore be employed as a ready means of preparing fluorine, the fluoride only requiring ...
