=FRACTURITE.=--A coal-mine explosive formerly on the Permitted
List, made by the British Explosives Syndicate, Ltd.--

=FUEL-ITE.=--There is a series of coal-mine explosives of
this name on the American Permissible List. Nos. 1 and 2 are
nitroglycerine explosives of the Carbonite type. No. 3 is an ammonium
nitrate explosive.
=FUELLPULVER= (or =FP.=) is the name given by the
Germans to mixtures of trinitro-toluene and ammonium nitrate used
for filling shell. Fp. 60/40, for instance, is a mixture of 60
parts trinitro-toluene and 40 parts of ammonium nitrate, and is
consequently the same as Amatol 40/60. Fp. without figures stands for
trinitro-toluene.
=*FULMEN POWDER= is a 33-grain smokeless powder for shot-guns
made by the Schultze Gunpowder Co.
=FULMENIT.=--A blasting explosive made by the German Nobel Co.,
containing ammonium nitrate, vegetable meal or charcoal, paraffin
oil, trinitro-toluene and guncotton.
=WETTER-FULMENIT= is a coal-mine explosive which has been
much used. It differs from the above in containing also sodium or
potassium chloride--
Fulmenit. Wetter-Fulmenit.

=FUMYL.=--A smoke-producing explosive containing trinitro-toluene and
ammonium chloride, used for opening poison-gas shell, etc.
=GATHURST POWDER.=--An explosive of the Grisounite class.
According to an analysis given in Cundill and Thomson’s Dictionary it
consisted of--
Ammonium nitrate 83·4
Dinitro-benzene 16·5
Moisture 0·1
=GEHLINGERIT.=--A German blasting explosive. Gesteins-Gehlingerit
III. contains--
Ammonium nitrate 80
Trinitro-toluene 15
Flour 5
Wetter-Gehlingerit, which is a coal-mine explosive, contains also
sodium or potassium chloride, and may contain up to 4 per cent. of
nitroglycerine to increase its sensitiveness.
=GELATINÉ À L’AMMONIAQUE.=--A Belgian explosive, a mixture of
blasting gelatine and ammonium nitrate.
=GELATINE DYNAMITE= is a mixture of blasting gelatine, potassium
nitrate and a little wood meal. That made in Britain must contain
between 70 and 77 per cent. of nitroglycerine; it may contain up
to 2 per cent. of calcium or magnesium carbonate, or 1/2 per cent.
of mineral jelly as a stabiliser. The following may be taken as an
example of its composition--
Nitroglycerine 74·5
Collodion cotton 5·5
Wood meal 4
Potassium nitrate 15·5
Calcium carbonate 0·2
Moisture 0·3
In America brands are made of 35 to 80 per cent. strength.
=GELIGNITE= is similar to Gelatine Dynamite except that it
contains a smaller proportion of blasting gelatine; in Britain the
percentage of nitroglycerine must be between 56 and 63, _e. g._--
Nitroglycerine 61
Collodion cotton 4·5
Wood meal 7
Potassium nitrate 27
Calcium carbonate 0·2
Moisture 0·3
There are also a number of modified Gelignites, which either contain
sodium or barium nitrate in partial or entire replacement of the
potassium nitrate, or else contain some substance to reduce the
freezing point of the nitroglycerine and so diminish the danger of
freezing, such as dinitro- or trinitro-toluene or dinitro-glycol.
=GESILIT.=--A German coal-mine explosive made by Nahnsen. It
contains blasting gelatine, inorganic nitrates, sodium chloride,
carbohydrates and dinitro-toluene--
