It is produced by the use of a simple electric furnace of the resistance type, where coke, sand, and sawdust are heated to a temperature of between 2000 degrees and 3000 degrees C. The chemical reaction involves the production of carbon monoxide, and gives a carbide of silicon, a crystalline solid which has the excellent abrasive properties mentioned.
He reached for his carbide lamp, hooked to a small chink of the hanging wall, and then pulled his hat over his bulging forehead. Carefully he attempted to smooth his straying mustache, and failing, as always, gave up the job. "I 'd be 'appy, just to look at it," he announced. "Come on. Let's forget 'oo they are and just be lookers-on." Fairchild agreed against his will.
Calcium carbide, employed in the production of acetylene gas, either for the purposes of artificial illumination, or for the manufacture of ethyl alcohol, is produced by subjecting a mixture of carbon and lime to the prolonged action of heat in an electric furnace.
"And look " Fairchild was beside him now, with his carbide "how everything's torn, as though from an explosion." "It seems that wye. But you can't tell. Rock 'as an awful way of churning up things when it decides to turn loose. All I know is we 've got a job cut out for us." There was only one thing to do, turn back.
"I guess Koku go pull shed down and stamp out fire." "Huh! Maybe yo' could do dat in cannibal land, where yo' all come from," spoke Eradicate, "but yo' can't do dat heah! 'Sides, de red shed will blow up soon. Dere's suffin' else in dere except carbide, an' dat's gwine t' go up soon, dat's suah!" "Maybe you get your strong man-mule, Boomerang," suggested Koku.
"So long as you've got plenty of firewood why not use it?" said he. "We want a light, too." "Here is the acetylene gas lamp," said Snap, picking it up from where it had fallen, near the doorway. "And the can of carbide," added Shep. "This will help us to start a fresh fire, even if the wood is wet," he continued.
The process involves merely a transformation at a high temperature, a portion of the carbon in the form of coke, uniting with pulverized lime to give the calcium carbide or CaC2.
Get a bite of something to eat, for you must surely want it; buy what you want for the car oil, carbide, and the rest, and get away to meet the pretty Pierrette. And again good luck to you!" he added, as he mixed a little more whisky and tossed it off. Then he shook my hand warmly.
Daly's driver was refilling the lamps with carbide, and when he finished asked for petrol. "Ye're for the road again," the man who brought the tin remarked. "For Langholm," replied the driver. "I don't expect we'll go farther to-night, but I must have things ready if the boss wants to go on."
And all three stopped at once. The hollow sound was coming directly to them now. Harry once more brought out his carbide to light it for a moment and to examine the timbering. "It's a good job!" he commented. "You could n't tell it five feet off!" "They 've made a cross-cut!" This time it was Anita's voice, plainly angry in spite of its whispering tones.
