DAHMENITE is an ammonium nitrate explosive which has been used to a considerable extent in Germany. One variety known as Dahmenite A, made by De Gezamenlijke Buskruidmakers van Noord-Holland, was formerly on the British Permitted List for use in dangerous coal mines—

Ordinary Dahmenite contains up to 15 per cent. of potassium nitrate instead of bichromate, and has been used for blasting clay. Some varieties contain curcuma meal and other constituents. The following are some examples—
