=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--

Ammonium nitrate 92·5 Naphthalene 5·5 Potassium bichromate 2

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--

Gesteins- Dahmenit. No. 76.

Ammonium nitrate 84·5 71·5 Potassium bichromate 2·5 0·5 Curcuma meal 12 6·25 Dinitro-benzene 1 -- Trinitro-toluene -- 12 Sodium chloride -- 9·75

=DENABY POWDER.=--There was formerly a blasting explosive of this name, consisting of a compressed mixture of Securite and charcoal--

Potassium and barium nitrates 73·2 Dinitro-benzene 21·5 Nitrocotton and charcoal 5·1 Moisture 0·2

In 1914 a coal-mine explosive was introduced under the same name and passed the Rotherham Test--

It is made by British Westfalite, Ltd.

=DENSITE.=--A Belgian blasting explosive containing one or more of the following nitrates: ammonium, strontium, sodium, potassium; also trinitro-toluene, and sometimes dinitro-toluene and ammonium chloride. This explosive is practically the same as Nitralite. Varieties have been made for use in coal mines.

See also Nitro-densite.

=DETONIT V.=--A German coal-mine explosive containing ammonium nitrate, charcoal, vegetable meal, neutral salts, and not more than 4 per cent. of blasting gelatine.

=DETONITE SPECIAL= is an American coal-mine explosive on the Permissible List. It contains ammonium nitrate.

=DOMINITE.=--A coal-mine explosive made by the Westphalia Anhalt Explosives Co. in Germany, and formerly on the British Permitted List--

Nitroglycerine 59·3 Nitrocotton 4 Paraffin oil 0·7 Ammonium oxalate 8·5 Potassium nitrate 18·5 Potassium chloride 4 Wood meal 5

=DOMINIT XI.=--A German blasting explosive containing ammonium nitrate, dinitro-toluene, glycerine, and not more than 4 per cent. of blasting gelatine.

=DOMINIT XVIII=, which has been introduced recently, contains up to 10 per cent. of potassium perchlorate, and is practically the same as Astralit V.

=DONARIT= is a German blasting explosive of the Grisoutine type made by the Carbonite Co. of Hamburg. As a standard for the sensitiveness of ammonium nitrate explosives, the Imperial German Railway Commission use Donarit of the composition--
