"Platinum" Quotes from Famous Books



... in the volcano of Popocatapetl, is bought up at the mint in the city of Mexico, where it is burned in a room lined with lead, and into which water is jetted until the smoke of the burning brimstone is condensed. This water of sulphur is then carefully collected, and distilled in a boiler of platinum, on which sulphur can not act. The sulphuric acid obtained by this distillation is used to separate the gold that is found in the silver bars from silver. This sometimes amounts to ten per cent. The acid ...

... find a soft woman's corpse. Glowing blue snows cast a howling darkness. On high poles a scarecrow, implored, hangs. Stores flicker dimly through frosted windows, In front of which human bodies move like ghosts. Students carve a frozen girl. How lovely, the crystalline winter evening burning! A platinum moon now streams through a gap in the houses. Next to green lanterns under a bridge Lies a gypsy woman. And plays ...

A blowpipe, a bit of candle, a small bottle of powdered borax, another of mercury, and a bent platinum wire, packed away in an empty jam-tin, formed his assayer's kit—a paraphernalia which induced as much mirth and scoffing contempt from Palmer Billy as it would have done from a skilled and cultured scientist, ...

When the zinc is brushed over with this mixture it oxidizes the surface, turns black, and dries in from twelve to twenty-four hours, and may then be painted over without any danger of peeling. Another and more quickly applied coating consists of, bi-chloride of platinum, 1 part dissolved in 10 parts of distilled water, and applied either by a brush or sponge. It oxidizes at once, turns black, and resists the weak acids, ...

To accomplish my plans I require hundreds of millions in gold, other hundreds of millions in platinum and noble metal, and some five kilograms of the bromide of radium—all of which I shall take from the planets of this Solar System before I leave it. I shall take them in spite of the puerile efforts of the fleets of your ...

If this rate were maintained we should at 60 km. in depth arrive at a temperature high enough to melt platinum, the most refractory of the known metals. What the law of temperature-increase at great depths is we do not know, but the temperature of the Earth's deep interior must ...

No. 10 wire, the conduit may be sufficient to permit the caloric to pass without increasing the molecular velocity of the metal to an appreciable degree, but if we cut the No. 10 wire and insert a piece of No. 40 platinum wire in the path, the amount of caloric flowing through the No. 10 wire cannot pass through the No. 40 wire, and the resistance so caused increases the molecular velocity of the No. 40 wire to such degree as to exhibit the phenomenon of incandescence, and this is the incandescent ...

This action breaks an electric current which has traversed a second electro-magnet F (Fig. 2), and releases ...
