Chloride of Magnesium
Dissolve magnesia in muriatic acid, evaporate to dryness, add an equal weight of muriate of ammonia, project the mixture into a red hot platinum crucible, and continue the heat until tranquil fusion is attained. Pour out the fused mass on to a clean stone; and, when solid, break it into pieces, and transfer to a warm, dry bottle. (Cooley.) Or: Dissolve magnesia in muriatic acid; evaporate to a specific gravity of 1.384; and put it, while hot, into a wide-mouthed flask to crystallize. (Paris Codex.) This chloride of magnesium is also called hydrochlorate or muriate of magnesia.
