Side 260 - York. *By the common method, the specific gravity equals the weight of the specimen in the air divided by the difference between the weight in air and the weight in water...
Side 210 - A view of the Lead Mines of Missouri : including some observations on the mineralogy, geology, geography, antiquities, soil, climate, population, and productions of Missouri and Arkansaw, and other sections of the Western Country.
Side 67 - Again, every flash of lightning not only generates nitric acid, — which, in solution in the rain, acts on the marble, — but also by its inductive effects at a distance produces chemical changes along the moist wall, which are at the present time beyond our means of estimating.
Side 176 - Veined marble, sawed, dressed, or otherwise, including marble slabs and marble paving-tiles, one dollar and ten cents per cubic foot (but in measurement no slab shall be computed at less than one inch in thickness).
Side 70 - Unfortunately sufficient and reliable data are not at hand for estimating accurately the comparative enduring powers of various stones under these trying circumstances. It seems, however, to be well proven that of all stones granite is the least fire-proof, while the fact that certain of the finegrained siliceous sandstones are used for furnace backings would seem to show that if not absolutely fire-proof, they are very nearly...
Side 73 - From all these causes, the commission are convinced that the only entirely reliable means of ascertaining the comparative capability of marble to resist the weather, is to study the actual effects of the atmosphere upon it, as exhibited in buildings which for years have been exposed to these influences. Unfortunately, however, in this country, but few opportunities for applying this test are to be found. It is true some analogous...
Side 75 - ... the stone adjacent to the seam presents an interrupted fractured margin; the small fragments having dropped out in the process of weathering. Limestones of this character are much better adapted to rough dressing, when the blows are directed away from the surface instead of against it, and when the entire surface shall be left of the natural fresh fracture. By this process the clay seams have not been crushed, nor the limestone margining them broken, and the stone withstands the weather much...
Side 84 - ... thus improving the quality. Glass rich in lime requires a higher temperature to melt and, because of this, is more destructive to the pots, but, used in proper proportions, lime promotes the fusion, aids in the decomposition of the materials and improves the quality of the glass. Lime glass can not compete with lead glass in brilliancy, but it is harder, not so easily scratched, holds its polish longer, is more elastic and consequently tougher, will stand higher temperature, resists better the...
Side 66 - ... was due partly to corrosion, but chiefly to the introduction of particles of soot and dust, which could be traced among the interstices and cleavage lamellae of the crystalline granules, for some distance back from the crust. It may be inferred, therefore, that the disintegration of the marble is mainly due to the action of carbonic acid in the permeating rainwater, whereby the component crystalline granules of the stone are partially dissolved and their mutual adhesion is destroyed. This process...
Side 101 - Batesville0 occurs in layers from 3 to 5 feet thick, and can be quarried in as large pieces as can be handled. In color and appearance it resembles the Indiana oolitic stone somewhat, but is harder and more crystalline than most of the Indiana stone and is harder to work. The stone found at the two other localities mentioned above is lighter colored, softer, and more easily wrought. Another variety occurring in the western part of Independence County is a hard, compact, close-grained, finely crystalline,...
