"Silicate" Quotes from Famous Books
 ... He adduces the experiments of Mr. Crosse, repeated by Mr. Weekes, who claim to have produced animalcules in considerable numbers, of a species before unknown, by passing a voltaic current through silicate of potash, and through nitrate of copper. The existence of entozoa, or parasitic animals, found in the interior of the bodies of other animals, and found nowhere else, is thought to support the same doctrine. The question is, How ...

... years preserved eggs in water glass, or soluble glass, also known as "Sodium Silicate," a thick liquid about the consistency of molasses. It is not expensive and may easily be procured at any drug store. She used the water glass in the proportion of 10 quarts of water to one pint of the water glass. The water glass, although in liquid form, is usually sold by the pound, ...

... In this investigation Faraday proved that light-vibrations are rotated by the action of a magnetic field. He employed the light of an ordinary Argand lamp, and polarized it by reflection from a glass surface. He caused this polarized light to pass through a plate of heavy glass made from a boro-silicate of lead. Under ordinary circumstances this substance exerted no unusual action on light, but when it was placed between the poles of a powerful electro-magnet, and the light was passed through it in the same direction as the magnetic flux, the plane of polarization ...

... or gray, or grayish brown, very thin, oval, then bell-shaped, minutely scaly, becoming smooth, prominently silicate or plicate, plaited. The gills are adnate, broad, white, gray, then black. The spores are black, oblong, 8 x 6 mu. The stem is very slender, becoming hollow, often curved. The entire plant is very fragile, and in age becomes ...

... crude sodium carbonate. If made by the ammonia process it may contain also sodium chloride, sulphate, and hydroxide; when made by the Le Blanc process it may contain sodium sulphide, silicate, and aluminate, and other impurities. Some of these, notably the hydroxide, combine with acids and contribute to the total alkaline strength, but it is customary to calculate this strength in terms of sodium carbonate; i.e., as though no other ...

... the detection of alkalies in silicates. Mix one part of the substance with about four parts of the hydrate of baryta, and expose it to the blowpipe flame. The hydrate of baryta combines with the silicic acid, and forms the super-basic silicate of baryta, while the oxides become free. The fused mass must be dissolved in hydrochloric acid, which converts the oxides into chlorides. Evaporate to dryness, and dissolve the residue in water. The silicic acid ...

... down, and the whole mould violently jolted by machinery to shake down the mixture and to get rid of air holes. While it is still wet the casting is taken out of the mould, its edges are cleaned, and after the lapse of one day it is placed in a bath, of silicate of soda. Should the casting be allowed to get dry before it is placed in this bath, no good results would be obtained; it is left in the bath for seven days. When delicate stone carvings have to be copied, the moulds are of a compound of gelatine, from ...

... Globigerinoe and black sand, probably greensand, as it makes a green mark when crushed on paper." Professor Bailey, examining these grains microscopically, found that they were casts of the interior cavities of Foraminifera, consisting of a mineral known as Glauconite, which is a silicate of iron and alumina. In these casts the minutest cavities and finest tubes in the Foraminifer were sornetilnes reproduced in solid counterparts of the glassy mineral, while the calcareous original had ...

... certainly never rightly grasp the nature of a hedgerow. Bellis perennis and Sinapis arvensis were not to be confounded, and Triticum repens was a sure sign of a bad farmer. Chemistry proved that too small a quantity of silicate made John Barleycorn weak in the knee; ammonia, animal phosphates, nitrogen, and so on, were mere names to many ignorant folk. The various stages and the different developments of insect life were next to ...
