=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-- Ammonium nitrate 80 Trinitro-toluene 12 Rye flour 4 Nitroglycerine 4 and this may be taken as the usual composition of the explosive, but the nitroglycerine is sometimes gelatinised with collodion cotton. =DONARIT A= contains up to 16 per cent. of aluminium powder and no nitroglycerine. =DONARIT V=, which has been introduced recently, contains up to 10 per cent. of potassium perchlorate, and is practically the same as Astralit V. Wetter-Donarit contains also sodium chloride or other cooling agent. Gelatine-Donarit contains up to 20 per cent. of dinitro-chlorhydrin gelatinised with collodion cotton, in addition to the constituents of Donarit, and may also contain sodium nitrate. =DORFIT= is a German coal-mine explosive made by the firm of Allendorf-- I. II. Gesteins. Ammonium nitrate 65 61 66 Potassium nitrate 5 5 5 Trinitro-toluene 6 15 15 Flour 4 4 4 Sodium chloride 20 15 10 =ALDORFIT= is a simpler mixture intended for use where there is no danger of fire-damp-- Ammonium nitrate 81 Trinitro-toluene 17 Flour 2 It is authorised in Great Britain. =PERDORFIT= contains not more than 52 per cent. of potassium perchlorate, sodium and ammonium nitrates, not more than 29 per cent. of trinitro-toluene and vegetable meal or gums. =DRAGONITE.=--A coal-mine explosive made by Curtis’s and Harvey, formerly on the Permitted List-- Nitroglycerine 35·5 Nitrocotton 2·5 Potassium nitrate 44·5 Vaseline 5·5 Wood meal and charcoal 12 =DREADNOUGHT POWDER.=--A coal-mine explosive made by Roburite and Ammonal, Ltd., for a time on the Permitted List-- _Date of Permit_ 1-9-13 Ammonium nitrate 75·4 Trinitro-toluene 4 Ammonium chloride 5 Sodium chloride 15·5 Red oil 0·1 Limit charge 32 oz. Power (swing of ballistic pendulum) 2·05” There is also Quarry Dreadnought Powder, which is not a permitted explosive. =DUNNITE.=--A high explosive used by the United States for filling shell. It is stated to give dangerous compounds with iron, so apparently is a compound of picric acid.
