CHLORIDE OF CALCIUM.
Reading edition
Chloride of Calcium.—This is so easily manufactured that any Daguerreotypist can make it with but little difficulty. Saturate dilated muriatic acid, say three pints of water to one of acid; this should be filtered through a sponge and then allowed to stand until all the aquus solution has evaporated and the calcium crystallized. This may be improved by it being placed in a crucible; and fused with a quick fire, then poured out on a flat stone. When cold, it should be broken and put in close bottles. This is much used by Daguerreotypists as it possesses a strong affinity for water; consequently, it is a valuable auxiliary in keeping the iodine dry. It is also much used for drying gases and absorbing water from ethereal and oily liquids, in organic analyses.
