A Chaldee word, importing the K.ey of Art; some explain it by sal mercurii, or sal philosophorum et artis: others say it is named elem-brot et sal fusionis, or sal fixionis. Alembroth desicca-tum is said to be the sal tartari; hence this word seems to signify alkaline salt, which opens the bodies of metals by destroying their sulphurs, and promoting their separation from the ores. From analogy, it is supposed to have the same effect in conquering obstructions and attenuating viscid fluids in the human body. A peculiar earth, probably containing a fixed alkali, found in the island of Cyprus, has also this appellation; and a solution of the corrosive sublimate, to which the muriat of ammonia has been added, that greatly assists the solubility of the mercurial salt, is called sal alembroth.
