 ... of hard and soft coal, coke, charcoal, graphite, peat, and petroleum. Note the distinctive characteristics of each. Discuss the uses. Try to set each on fire. Note which burns with a flame when laid on the coals or placed over the spirit-lamp. Put a bit of soft coal into a small test-tube; heat and light the gas that is produced. This ...

... directly in front of the projector lens he found another of the same arrangements, but with a difference. This one was modern, and it had been painted to prevent rusting. There were traces of graphite or graphite grease where the pins went through ...

... of a pure fire clay, mixed with finely ground cement of oil crucibles, and a portion of black lead or graphite; some pounded coke may be mixed with the plumbago. The clay should be prepared in a similar way as for making pottery ware. The vessels, after being formed, must be slowly dried, and then properly ...

... hydrogen united in certain proportions, indicated chemically by the symbol CH4. We find, in fact, that rock gas possesses a close relationship, chemically speaking, with many familiar carbon compounds, and of these latter, petroleum itself, asphaltum, coal, jet, graphite or plumbago, and even the diamond itself—which is only crystallized carbon after all—are ...

... this is quite sufficient, without relying on the evidence of the great quantities of carbon in the earliest (Laurentian, Huronian, &c.) strata in the form of graphite. It is possible, or even probable, that this may be due to carbon supplied by masses of little ...

Therefore, from its chemical, as well as from its commercial aspect, the diamond stands alone as the ...

The same thread answers for the nut which clamps the cylinder in the plate, B, and for the gland, b, of the stuffing box, which screws over the beveled end of the cylinder, and contains fibrous packing filled with asbestos or graphite. The posts, C, are shouldered at the ends and secured in their places by nuts. Their bearing surface on the plate, D, is increased by the addition of a collar screwed on. The posts are made from drawn rods of brass, and need no turning except ...

... thus illustrating what chemists call allotropism, which means that substances of identical chemical composition sometimes possess altogether different outward and physical appearances. Thus the three states in which pure carbon exists, viz., diamond, graphite, or plumbago, and charcoal are as different as possible, and yet chemically they are all exactly the same substance. The diamond is the purest carbon, and occurs in the crystalline form known as a regular octahedron; the diamond is one of the hardest substances known, and is therefore, utilized ...

... electric furnace. It was the invention of Edward B. Acheson, a graduate of the Edison laboratories. Acheson, in 1891, was trying to make artificial diamonds and produced instead the more useful carborundum, as well as the Acheson graphite, which at once found its place in industry. Another valuable product of the electric furnace was the calcium carbide first produced in 1892 by Thomas L. Wilson of Spray, North Carolina. This calcium carbide is the basis of acetylene ...

... precipitated from the sky at Mazapil, within view of a ranchman.[1244] Scientific examination proved it to be a "siderite," or mass of "nickel-iron"; its weight exceeded eight pounds, and it contained many nodules of graphite. We are not, however, authorised by the circumstances of its arrival to regard the Mazapil fragment of cosmic metal as a specimen torn from Biela's comet. In this, as in the preceding case, the coincidence of the fall with ...

... allotropic forms, amorphous boron having been obtained simultaneously and independently in 1809 by Gay Lussac and Davy. Before leaving this phase of inorganic chemistry, we may mention other historical examples of allotropy. Of great importance is the chemical identity of the diamond, graphite and charcoal, a fact demonstrated in part by Lavoisier in 1773, Smithson Tennant in 1706, and by Sir George Steuart-Mackenzie (1780-1848), who showed that equal weights of these three substances yielded the same weight of carbon dioxide on combustion. The allotropy ...
