After oxygen, silicon is the most abundant element in the earth s crust, It occurs extensively as the oxide, silica, in various forms, for example, flint, quartz, sand, and as silicates in rocks and clays, but not as the free element, silicon. Silicon is prepared by reduction of silica, Si02- Powdered amorphous silicon can be obtained by heating dry powdered silica with either powdered magnesium or a...

Frit may be milled dry or wet. The long established dry process is used for cast iron baths and for chemical plant. Vitreous enamel application by a dry electrostatic method is being used on an increasing scale. In these cases, the frit is milled alone, or with inorganic colouring or refractory additives. This is achieved in cylinders using balls of porcelain, steatite or more dense alumina, or with pebbles of flint, to produce a fine powder of predetermined size. 

Silica, or silicon dioxide, occurs in various forms including chalcedony, which is a decorative material chert, which is used in abrasives flint, which is used in abrasives and ceramics jasper, which is used for decorative purposes quartz, which is a constituent of sand tripoli, which is found in scouring powders, polishers, and fillers cristobalite, which is used in high temperature casting and specialty ceramics diatomaceous earth, which is used in filtration processes and as a filler and finally, silica gel, which is used in dehydrating and drying. Note, however, that the material of concern is silica, and not silicates, which are relatively harmless derivatives of silica, nor silicones, synthetic materials used especially as lubricants. Neither silicates nor silicones cause proliferative conditions. 

Statistics.—For all purposes, about twenty-live thousand tons of manganose are used annually and of this quantity, from seventeen to eighteen thousand are employed for the manufacture of bleaching powder. The largest makers of the latter article are the Tennants of Glasgow, and Muspkatts of Liverpool, and Flint, North Wales. 

Davy found that he could reproduce the blue glass above mentioned by fusing together fifteen parts of sodium carbonate, twenty parts powdered flint and three of copper filings. This is of interest in connection with a statement of Vitruvius to which reference will be made later. 

Si(OH)4. When silica, in the form of flint, or fine sand, or powdered rock-crystal is either fused with caustic soda or potash, or heated under pressure with a solution of one or other of the alkalies, an orthosilicate is produced, possessing the formula Si(ONa)4 or Si(OK)4. These silicates are soluble in water, 2nd as they resemble glass in appearance, they are usually named soluble glass. If hydrochloric acid is added to the solution of one of... 

Terrazzo is made from powdered marble, cement, goat s milk, and a few other things, but steel will not strike a spark from marble. It needs a harder rock, like flint. Oh, well...
