Part 21

=KYNARKITE= is a coal-mine explosive of the Carbonite type made by Kynoch, Ltd. It is no longer on the Permitted List--

No. 2. Date of Permit 1-9-13 15-1-15 Nitroglycerine 25 26 Potassium nitrate 28 29·5 Barium nitrate 3 -- Dinitro-toluene -- 2·5 Wood meal 39 34 Ammonium oxalate 5 8

Limit charge 20 28 oz. Power (swing of ballistic pendulum) 2·21 2·06”

=KYNITE= was a coal-mine explosive on the old Permitted List, but has been superseded by Kynarkite--

Kynite Kynite. Condensed.

Nitroglycerine 26 25 Barium nitrate 33 33·5 Wood meal 40·7 6·5 Starch -- 34·7 Calcium carbonate 0·3 0·3

=*LAFFLIN AND RAND W.A.= was a tubular smokeless powder tried in America for small arms. It consisted of--

Guncotton 67·25 Nitroglycerine 30 Metallic salts 2·75

gelatinised by means of 40 parts of acetone. A gelatinised dense shot-gun powder of similar composition was also made.

=L.C. PULVER= is a German Cheddite.

Gesteins-=LEONIT= is a German perchlorate explosive for blasting rock--

Alkali perchlorate about 60% Ammonium nitrate 10 Nitro-compounds 15 Meal 10 Blasting gelatine 4

It is practically the same as Permonit A.

Neu-=LEONIT= is a modification of this for use in coal

I. II. Potassium perchlorate 35 35 Ammonium nitrate 20 10 Sodium nitrate -- 3 Trinitro-toluene 5} 11 Dinitro-toluene 5} Wood meal 3 2 Vegetable meal 4 5 Blasting gelatine 4 4 Sodium chloride 24 30

It is practically the same as Wetter-Persalit.

=LIGDYN= is a nitroglycerine explosive similar to American dynamite made in South Africa. 40 per cent. Ligdyn consists of--

Nitroglycerine 40 Sodium nitrate 45 Wood meal 13 Wheat flour 2

=*LIGHTNING.=--A 33-grain smokeless shot-gun powder made by the Schultze Gunpowder Co. See Schultze Powder.

=LIGNOSIT= is a German blasting explosive containing a considerable percentage of ammonium nitrate. Lignosit I. contains also aromatic nitro-compounds, of which not more than 15 per cent. must be trinitro-compounds or wood meal, and not more than 6 per cent. of potassium nitrate, not more than I per cent. of collodion cotton and bauxite or salts, such as sodium chloride or carbonate.

Lignosit II. may contain up to 10 per cent. of collodion cotton, but no wood meal or nitro-compounds. It is somewhat sensitive.

Lignosit III. differs from I. in that it may contain up to 4 per cent. of blasting gelatine and contains no bauxite.

The object of adding the neutral salts is evidently to make the explosive safer in coal mines. When intended for this purpose it is called Wetter-Lignosit I. or III.

Lignosit IV. consists of ammonium nitrate, not more than 13 per cent. of trinitro-toluene, not more than 13 per cent. of aluminium powder, and wood meal.

=LITHOFRACTEUR= is a name that has been given to more than one explosive. One introduced about 1873 by Krebs and Co. of Deutz, near Cologne, consisted of nitroglycerine absorbed in kieselguhr mixed with nitrates, charcoal or coal and sulphur. Some of it was imported into England at one time.

=LOEWENPULVER= or Castroper Sprengpulver is a German blasting powder consisting of a compressed or granulated mixture of sodium nitrate, manganese dioxide, sulphur and carbonaceous substances such as briquette powder or coal. It may also contain potassium nitrate, wood meal or tar.

=LOMITE NO. 1= is an American coal-mine explosive on the Permissible List. It is a low-grade dynamite containing hydrated salts.

=LOWINITE NO. 2-B= is an American coal-mine explosive on the Permissible List. It is an ammonium nitrate explosive.
