Cadmium Yellow, Sulphuret of Cad-m'uiiii. The new metal, cadmium, affords, by precipitation with solution of sulphuretted hydrogen, a bright warm yellow pigment, which passes readily into tints with white lead, appears to endure light, and remain unchanged in impure air; but the metal from which it is prepared being hitherto scarce, it has been little employed as a pigment, and its habits are, therefore, not ascertained. A yellow pigment, under this denomination, has, however, been introduced into commerce, which is of a powdery texture and a bright yellow, between the colours of chrome and orpiment.
