Show nay. i Mas f'uuud New stetal. George A. Clarke, an experienced ironworker iron-worker of Boston, claims to have discovered dis-covered an ore in the Eocky mou.itains which lie believes is new to tlio world. 1 Ho says of it: "I took specimens of the orn to as-sayerwin as-sayerwin Cincinnati, Chicago and Boston, and no one of them could tell me the name of tho mineral. Then I began here a series of experiments myself, mix-ing mix-ing it with molten iron. It combined perfectly with tho iron, and I found that only a small qnuntity was necessary to increasa the fluidity of tho metal. It rendered the iron ductile, and in low grades acted as a purifier. The product of the alloy was a homogeneous metal of very fine pores, capable of higher finish than before. The slag expelled by its use contained no metal, and was very light. In tho treatment of iron with only one per cent, of this new ore tho former's tensile strength, was in-cren-seil from 10 to 25 per cent. Using only half of one per cent, of this or in a mixture with copper, 1 found that it gavo the metal greater density and u great increase from GO to 100 per cent. of tensile strength. Tho resulting result-ing metal, too, is cajiable of a high polish. In a word, I found that tlio ore increased the tensile strength and tho fluidity under heat of both theso metals and makes them both of finer grain. It i3 non-corrosive." Sir. Clarke produced a handful of the ore a sub.-tance that looked like a fine sandstone, save that it was black, and many pieces of it presented highly polished pol-ished surfaces as smooth as a bit of glass. Mr. Clarke refused to state the location of the field, which, he said, was exposed over tho space of an acre, as he is trying to get control of it first. Cor. Chicago Tribune. |
