(From the Hebrew term kadam,) also chlimia, catimia. Dioscorides meant by it the recrement which arises from brass whilst melting. Galen applied it to the recrement of brass, and a stone found in some mines called cadmia lapidosa, supposed to be the aeruginosus lapis. The calamine stone is now called cadmia, and the Germans have given this name to cobalt; whence Agricola says, that there are three sorts; one metallic, one fossile, and one of the furnaces; instanced in the succeeding.
Cadmia metallica. See Cobaltum.
Cadmia fossilis and lapidosa. See Calaminaris lapis.
Cadmia factitia and fornacum. See Tutia.
The burnt cadmia receives different names, according to the part of the furnace from whence it is collected; if in its upper part, resembling a cluster of grapes, botrytes or botritis; if in the lower part, placitis. But Schroeder says, that the botritis is collected in the middle, the placitis in the upper, and the ostracitis, which is thin, earthy, and black, in the lower part of the furnace. See also Calamitis, and Pompholix, which are truly cadmias.
