Department of Experimental Agricultural Chem- istry, Pennsylvania Station. (6) Calcium Oxide, called also Burnt Lime, Stone Lime, Lump Lime, Rock Lime, Caustic Lime, and Quicklime, CaO.—This is prepared from any of the forms of calcium carbonate, although usually from limestone, by "burning," either in specially built kilns (Fig. 61) or in piles in the field. Li either case the limestone is alternated with wood or coal and the latter by burning produces sufficient heat to drive off carbon dioxide from the limestone and leave calcium oxide, thus: CaCOs + heat = CaO + CO2. If pure this form of lime is all valuable in neutralizing acids and is the most concentrated form that can be Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Stoddart, Charles William, 1877-.
