ALBIONITE.—A mixture of gelignite and ammonium oxalate. It was formerly on the Permitted List.
ALBIT.—A German chlorate explosive introduced in 1915 in consequence of the scarcity of nitrates due to the War. It is defined as consisting of not more than 80 per cent. sodium or potassium chlorate, not more than 4 per cent. nitroglycerine, and mono- or dinitro-hydrocarbons. It may also contain inorganic salts and carbon carriers such as vegetable meal, oils, soaps or carbohydrates. A variety made for use in coal mines is called Wetter-Albit or Kohlen-Albit.

It contains not more than 80 per cent. sodium or potassium chlorate, or not more than 80 per cent. sodium, potassium or ammonium perchlorate, and 19 per cent. of aromatic nitro-hydrocarbons and nitrocotton, also coal, hydrocarbons or carbohydrates, and nitrates. The chlorate mixtures must not contain ammonium salts. Alkalsit I contains not more than 27 per cent. of potassium perchlorate, ammonium nitrate, not more than 24 per cent. of sodium nitrate, not more than 8 per cent. of trinitro-toluene, also wood meal, flour and nitro-naphthalene. Alkalsit A contains not more than 55 per cent. of potassium perchlorate, ammonium nitrate, not more than 31 per cent. trinitro-toluene, and not more than 5 per cent. of a neutral liquid mixture of nitrated toluenes. Alkalsit B is similar except that it contains also ammonium nitrate.
ALSILITE S.G.P.—A Belgian coal-mine explosive on the list of Explosifs S.G.P. It is of the Ammonal type—
Ammonium nitrate 62
Trinitro-toluene 11
Ferro-silicon-aluminium 5
Sodium chloride 22
Charge limite 900 g.
ALUMATOL.—A mixture of ammonium nitrate, trinitro-toluene and a little aluminium powder, used for charging trench-mortar bombs, etc.
AMASITE.—A coal-mine explosive formerly on the Permitted List—
Ammonium perchlorate 34
Sodium nitrate 31
Myrobolans 34·7
Agar agar 0·3
It was made by the Société Anonyme de Vilvorde in Belgium, and was originally called Ugolite.
Rock Amasite and S.T. Amasite are non-permitted explosives of composition somewhat similar to the above.
AMATOL.—A mixture of ammonium nitrate and trinitro-toluene. The composition is shown by the figures placed after the name; thus Amatol 40/60 contains 40 per cent. ammonium nitrate and 60 per cent. trinitro-toluene, and Amatol 80/20 consists of 80 parts ammonium nitrate and 20 parts trinitro-toluene. These explosives are used very extensively for filling shell and other projectiles. The mixtures rich in trinitro-toluene can be cast after being heated to temperature above the melting-point of this constituent, but those rich in ammonium nitrate are stemmed into the projectile hot or pressed. Similar mixtures are used by the Germans and other powers under various names. In Germany it is called Füllpulver (q. v.).
AMATOXOL.—A mixture of ammonium nitrate and Toxol, which consists of trinitro-toluene and trinitro-xylene.
*AMBERITE.—A smokeless shot-gun powder made by Curtis’s and Harvey at Tonbridge. Amberite No. 1 contained nitroglycerine as well as nitrocotton and various other substances. According to “Arms and Explosives,” 1917, p. 78, a sample of Amberite No. 2 had the composition—
Insoluble nitrocotton 18·6
Soluble ” 46·0
Nitrates of potassium and barium 28·0
Vaseline 6·0
Volatile matter 1·4
This is still on the market. It is a fibrous 42-grain bulk powder.
*AMIDE POWDER or Chilworth Special Powder was an early attempt at a smokeless powder. Under the name of Amidpulver it was used by the German artillery for some years in the ’eighties of the last century. Its composition was—
Ammonium nitrate 35-38
Potassium nitrate 40-46
Charcoal 14-22
See also Ammonpulver and Hebler Powder.
AMMONAL is a blasting explosive containing ammonium nitrate, aluminium powder, charcoal, and generally trinitro-toluene. It was patented in 1900 by G. Roth of Vienna, and the following are some of the compositions made by his firm at Felixdorf in Austria—
a b c d
Ammonium nitrate 80·75 90 88 80
Aluminium 15 4 8 18
Charcoal 4·25 6 4 2
More violent mixtures made by the same firm are—
I II
Ammonium nitrate 46 32
Trinitro-toluene 30 50
Aluminium 22 16
Charcoal 2 2
and modifications of this have been used largely in the British service. It is not suitable for use in underground workings as it forms on explosion the poisonous gas carbon monoxide, unless the proportion of ammonium nitrate be large. It has been used for charging grenades, and by the Austrians for trench howitzer bombs.
When the explosive is detonated, the aluminium is converted into the oxide, evolving no gas, but a considerable amount of heat, which increases the power of the explosive. The aluminium powder also renders the explosive easier to detonate.
Three explosives of this type passed the Woolwich Test, and were on the old Permitted List for coal mines, namely, Ammonal B, Ripping Ammonal and Saint Helen’s Powder (q. v.).
Ammonal B. Ripping Ammonal.
Ammonium nitrate 94·5 86
Aluminium 3 8
Charcoal 2·5 2·5
Potassium bichromate — 3·5
No explosives containing aluminium are on the present Permitted List.
AMMONCAHUECIT } CAHUECIT.
} See
AMMONCARBONIT } CARBONIT.
AMMONIAKKRUT was the first ammonium nitrate explosive. It was invented by J. Ohlsson and J. H. Norrbin, two Swedes, and was protected by English Patent 2766 of 1869. It consisted of ammonium nitrate together with 5 or 10 per cent. of charcoal, coal dust, etc., to which mixture was added 10 to 30 per cent. of nitroglycerine to make it less difficult to detonate.
AMMONITE is a coal-mine explosive of the Favier type, made by the Miners’ Safety Explosives Co. The original composition, which passed the Woolwich Test was—
Ammonium nitrate 88
Dinitro-naphthalene 12
To pass the more severe Rotherham Test a number of compositions have been made and approved, but some of them have been repealed. Those now on the Permitted List are—
Ammonite No. 1. Ammonite. Ammonite No. 5.
Date of Permit 29-8-14 5-11-17 2-8-18
Ammonium nitrate 74·5 73·5 74·5

Sodium chloride 20·5 21 20·5
Limit charge 24 18 26 oz.
Power (swing of ballistic pendulum) 2·42 2·44 2·41”
Ammonite No. 1 is used on a considerable scale in coal mines. A non-permitted explosive called Ripping Ammonite is also made.
*AMMONPULVER is a propellant which was used by the Austrians from 1890 to 1896 in guns of various calibres—
Ammonium nitrate 80-90
Charcoal 10-20
It was superseded by a powder of the ballistite type, but has been reintroduced recently by the Germans to replace a part of the charge of nitrocellulose powder in their field gun. The advantages claimed for it are small erosion of the gun, absence of muzzle flame, chemical stability, and cheapness. On the other hand, it gives high pressures, and if used by itself requires a gun with a specially large chamber; but the most serious objection to it is that on keeping, physical changes take place in the pellets, leading to the production of very high pressures. It is said that moisture promotes these changes. See also Amide Powder.

It is authorised for manufacture in, or importation into the United Kingdom.
*BALLISTITE.—One of the first military smokeless powders, invented by Nobel. It consisted of about equal parts of nitroglycerine and soluble nitrocotton incorporated together under water, then passed repeatedly through rolls and cut into flakes. It was adopted by a number of Continental powers, but in consequence of the severe erosion of the guns which it caused, it has been modified or abandoned. The percentage of nitroglycerine is reduced, and consequently it is necessary to use a solvent such as acetone. A little mineral jelly or other stabiliser is sometimes added.

No. 1.
Date of Permit 3-2-16
Ammonium nitrate 63·5
Dinitro-benzene 15
Sodium chloride 16·5
Starch 5
Limit charge 20
Power (swing of ballistic pendulum) 2·74
BENTAL COAL POWDER.—An American coal-mine explosive on the Permissible List. It is an ammonium nitrate explosive.
BITUMINITE.—There are several coal-mine explosives of this name on the American Permissible List. Nos. 1, 3, 4 and 8 L.F. are nitroglycerine explosives. No. 5 is an ammonium nitrate explosive.
BLACK DIAMOND.—There are several coal-mine explosives of this name on the American Permissible List. Nos. 2A, 3A and 6 L.F. are nitroglycerine explosives, whereas Nos. 5, 7 and 8 are ammonium nitrate explosives.
BLACK POWDER is a name for ordinary gunpowder, a mixture of potassium nitrate, sulphur and charcoal.
BLASTINE is a high explosive having approximately the composition—
Ammonium perchlorate 60
Sodium nitrate 23
Dinitro-toluene 11
Paraffin wax 6
As the sodium nitrate in the above is not equivalent to the ammonium perchlorate, part of the chlorine is given off in the form of the poisonous gas, hydrogen chloride (hydrochloric acid).
BLASTING GELATINE.—Nitroglycerine, stiffened by having collodion cotton dissolved in it. Discovered by Nobel in 1875. It contains about—
Nitroglycerine 93
Collodion cotton 7
and also often a fraction of a percentage of calcium or magnesium carbonate to increase its stability. This is the most powerful of all the explosives in common use.
BOBBINITE.—The only explosive of the gunpowder class the use of which is permitted in coal mines in England. In most foreign countries explosives of this class are not allowed to be used in them at all. The permission is only temporary, but has been extended to the end of 1920, and is restricted to mines that are not gassy or dangerous from coal dust. There are two definitions, but the second is the one that is generally manufactured apparently—
First. Second.
Potassium nitrate 63·5 65
Charcoal 18·5 20
Sulphur 2 2
Sulphates of ammonium and copper 15 —
Rice or maize starch — 9
Paraffin wax — 3
Moisture 1 1
More than a million pounds of this explosive are used in coal mines every year. It shatters the coal less than high explosives do.

BROWN POWDER. See COCOA POWDER.
BRUGÈRE’S POWDER consisted of—
Ammonium picrate 54
Potassium nitrate 46
It was stated to give good results in the Chassepôt rifle, but picrate mixtures are liable to detonate, and are therefore dangerous to use as propellants.
BULL DOG Gunpowder Pellets were used in coal mines. They contained the same constituents as Bobbinite, which superseded them, but in different proportions.
Explosifs C were mixtures of ammonium cresylate with ammonium or sodium nitrate. They were made in France at one time, but their manufacture was dropped, as they were more expensive to make than Grisounite, and no more powerful.
CAHUECIT.—This was invented in the ’seventies of the last century by R. Cahuc, and was manufactured at Dartford in Kent under the name of Safety Blasting Powder or Carboazotine. It is still made in Germany. The ingredients are—
English. German.
Potassium nitrate 64 70
Sulphur flowers 12 12
Lampblack or soot 7 8
Bark or wood pulp 17 10
to which are added a few per cent. of sulphate of iron. The incorporation is carried out with the assistance of a considerable quantity of water, which is afterwards evaporated off. The mixing is not very thorough. The explosive is a comparatively mild one, but is used sometimes for blasting basalt. In the German explosive the potassium nitrate may be replaced by the corresponding sodium salt.
AMMONCAHUECIT.—In this explosive the potassium nitrate is replaced mainly or wholly by ammonium nitrate, and it contains not more than 15 per cent. of trinitro-toluene or trinitro-naphthalene or other nitro-body.
The brand labelled “Fram” contains ammonium nitrate, not more than 25 per cent. of trinitro-toluene gelatinised with 4 per cent. collodion cotton, wood meal or other vegetable meal and neutral stable salts. The brand “Indra” is similar, except that it contains also not more than 10 per cent. potassium nitrate, and the percentage of trinitro-toluene may be raised to 20.
CAMBRITE is a coal-mine explosive of the Carbonite type made by Nobels at Ardeer. It consists practically of Nobel Carbonite, to which 8 per cent. of a cooling agent has been added. Unlike most of the explosives on the old Permitted List, it passed the Rotherham Test with practically no alteration—

CAMERON MINE POWDER.—There are a number of coal-mine explosives of this name on the American Permissible List. Nos. 1a, 2a and 2a LF are ammonium nitrate explosives, whereas Nos. 3a and 5a are nitroglycerine explosives.
*CANNONITE was a smokeless powder made by a firm called the War and Sporting Smokeless Powder Syndicate, Ltd. It consisted of about 86 per cent. of nitrocellulose mostly insoluble in ether-alcohol, and a few per cent. of barium nitrate, together with small quantities of some of the following: potassium nitrate, charcoal, lampblack, vaseline, rosin, stearine, dinitro-benzene, trinitro-toluene, potassium ferro-cyanide, graphite. For shot-guns the powder was of the forty-two grain type, dense and gelatinised. The rifle powder was colloidal. These powders were made in the ’nineties of the last century.
CARBITE D’ABLON is a sort of Carbonite made in France—
Nitroglycerine 26
Potassium nitrate 33
Wood meal or flour 41
CARBOAZOTINE. See CAHUECIT.
CARBO-DYNAMITE was an explosive patented by W. D. Borland. It differed from ordinary dynamite in that the nitroglycerine was absorbed in cork charcoal instead of kieselguhr. One part of the charcoal sufficed to absorb nine parts of nitroglycerine.
CARBONITE (or Karbonit) was one of the earliest and one of the most successful coal-mine explosives. It was first made by Bichel and Schmidt at Schlebusch in Germany in 1885, and after some modifications gave satisfactory results at the Neunkirchen testing station in 1887. It contains about 26 per cent. of nitroglycerine, 33 per cent. of a nitrate, and 40 per cent. of wood meal or starch flour, and small quantities of other substances. Nobel Carbonite passed the Woolwich Test and had the composition—
Nitroglycerine 26
Barium nitrate 4
Potassium nitrate 29
Wood meal 40·5
“Sulphuretted benzol” 0·25
Sodium and calcium carbonates 0·25
The Carbonite made at the works of the Carbonite Syndicate at Schlebusch, and imported into Great Britain, was practically the same as this, but they also made another explosive which passed the Woolwich Test, and contained 35 per cent. of nitroglycerine gelatinised with nitrocotton, and smaller proportions of nitrates and wood meal than are given above: this was called Extra-Carbonite. They have also made explosives to numerous modifications of this formula for use on the Continent. The essential feature of all of them is that they contain so much of the combustible constituents, such as wood meal, that most of the carbon appears in the products of explosion as carbon monoxide, and the temperature of the gases is consequently low.
Nobels at Ardeer also made a low freezing explosive in which part of the nitroglycerine was replaced by a nitro-compound. This was called Arctic Carbonite—
Nitroglycerine 15·5
Nitro-hydrocarbon 10·5
Potassium nitrate 42
Wood meal 31·7
Calcium carbonate 0·3
Various manufacturers have made explosives of the type of Carbonite and placed them on the market under different names, such as Tutol, Kolax, Kohlen-Carbonite, Minite and Colinite. These, however, do not pass the Rotherham Test for Permitted Explosives, unless ammonium oxalate or other cooling agent be added, as in the case of Cambrite, Super-Kolax and Britonite No. 2.
On the Continent, explosives similar to Arctic Carbonite have been produced under the names Antigel de Sûreté and Ingélite.
There are several Carbonites on the American Permissible List. Of these Nos. 1 to 4 are in order of diminishing violence: Nos. 5 and 6 are low freezing varieties. There are also a number of other explosives of the Carbonite type on the List.
Ammonkarbonit is a German coal-mine explosive, containing about 80 per cent. of ammonium nitrate and 4 per cent. of blasting gelatine, together with 5 or 10 per cent. of potassium nitrate, and a combustible such as flour, starch or coal dust. Sodium or potassium chloride may be added as a cooling agent. It has been used for blasting clay.
Gelatine-Karbonit is a Carbonite containing ammonium nitrate, and a considerable proportion of nitroglycerine gelatinised with collodion cotton.
Halokarbonit is similar to Ammonkarbonit, except that a considerable proportion of the ammonium nitrate is replaced by other nitrates.
CARLSONITE was the first ammonium perchlorate explosive submitted to H.M. Inspectors of Explosives. It was proposed in 1898 by Carlson of Stockholm, and some of the mixtures were reported on favourably, but no licence was ever taken out in the United Kingdom for this explosive.
C.E. (Composition Exploding) is the same as Tetryl.
CELTITE was a coal-mine explosive made by Dr. R. Nahnsen & Co., Hamburg, and formerly permitted for use in British coal mines, having passed the Woolwich Test.
Nitroglycerine 57
Nitrocotton 3
Potassium nitrate 19
Wood meal 9
Ammonium oxalate 12
It was also called Zeltit.
*CENTRALITE is not an explosive, but is a name given to a substance which has been used to modify the surface of smokeless powder, and make it burn progressively. The substance is dimethyl-diphenyl-urea. (See Brit. Pat. 29,882 of 1909.) It acts also as a stabiliser.
CHEDDITE is a chlorate explosive which has been rendered less sensitive by having the particles of chlorate coated with castor oil or paraffin wax. It is manufactured by the French Government at the Vonges Powder Works, and has also been made in other countries. The two types that have been most used in France are—
O2 or No. 4. O5 or No. 1.
Potassium chlorate 79 —
Sodium chlorate — 79
Castor oil 5 5
Mononitro-naphthalene 1 —
Dinitro-toluene 15 16
*CHEESA STICKS are sticks of cordite coated with powdered ammonium oxalate and shellac. They are used in South Africa as fuses for blasting charges. They are authorised in England only for manufacture and immediate export.
*CHILWORTH SMOKELESS POWDER. See C.S.P.
*CHILWORTH SPECIAL POWDER. See AMIDE POWDER.

COLLODION COTTON is a variety of nitrocotton of low nitration, almost completely soluble in a mixture of ether and alcohol. It contains not more than 12·3 per cent. of nitrogen. It also dissolves in nitroglycerine and liquid nitro-compounds, rendering them gelatinous and so preventing their exudation.
*COOPPAL’S POWDER.—A Belgian smokeless shot-gun powder. Formerly it was much the same as Schultze Powder, consisting of nitrolignin carefully purified, and mixed with nitrates with or without the addition of starch. The following analyses were published in “Arms and Explosives” for July 1917—
No. 1. 1892. Fibrous 42-grain bulk. No. 2. 1900. Gelatinised 30-grain dense.

CORDITE is the principal smokeless powder of the British Services. It was originally adopted in 1888, and is made by mixing nitroglycerine with guncotton and mineral jelly (a sort of crude vaseline), and incorporating them together with the aid of acetone, which gelatinises the guncotton. In consequence of the severe erosion of the guns experienced during the South African War the proportions were altered, some of the nitroglycerine being replaced by guncotton. The propellant thus “modified” is called Cordite M.D., whereas that of the original composition is Cordite Mk.I. Both are still in use, especially M.D.—
Mk. I. M.D.
Guncotton 37 65
Nitroglycerine 58 30
Mineral jelly 5 5
During the great European War a further variety was introduced to extend the basis of supply of solvents. This is called Cordite R.D.B. (Research Department B), and contains a nitrocotton of comparatively low nitration that can be gelatinised by means of a mixture of ether and alcohol—
Nitrocotton 52
Nitroglycerine 42
Mineral jelly 6
It is designed to give about the same ballistics as Cordite M.D. A further letter is sometimes added to show the form of the powder. Thus Cordite M.D.T. is M.D. pressed into tubes; S. stands for strip. The size is indicated by a numeral, which shows the diameter in hundredths of an inch of the die through which it has been pressed. In the case of tubular powder both the external and internal diameters are given approximately: e. g. Cordite M.D.T. 5-2.

Nitroglycerine 75
Kieselguhr 25
the explosive being held in the pores of the kieselguhr. In other dynamites the nitroglycerine is absorbed in a material like wood meal, and a nitrate is added to oxidise the latter on explosion.
In Gelatine Dynamite the nitroglycerine is gelatinised with collodion cotton. See under Gelatine.
American Dynamites are not generally gelatinised with collodion cotton. They are made in a number of grades, depending on the percentage of nitroglycerine.
For further details about various dynamites, see textbooks on explosives.

FAVIER explosives consist essentially of ammonium nitrate mixed with nitro-compounds. Favier took out patents in 1884 and 1885 for mixtures of ammonium nitrate with mononitro-naphthalene, paraffin and resin. Their manufacture was undertaken soon afterwards by the French Government, and is still continued under the names of Explosifs N, or Explosifs Favier or Grisounites. Their composition has been varied from time to time, but the following are those now authorised—
Grisou- naphtalite- couche. Grisou- naphtalite- roche Grisou- tetrylite- couche. For mines free from fire-damp, etc.
N1a. N4 . N1b. N1c.

Potassium nitrate — 5 — 5 5 —
Dinitro-naphthane — — 8·5 8·5 — 12·6
Trinitro-naphthalene 5 5 — — — —
Tetryl — — — — 7 —
The Grisounites-couche are used in the coal seams as they have theoretical temperatures of explosion of 1500° or less, but N1a has been replaced to a considerable extent by N4, because the presence of a proportion of potassium nitrate is found to increase the safety; these are both coloured green. The Grisounites-roche have theoretical temperatures of explosion of 1900° or less, and are used in the rocks in coal mines. N1b is dyed rose colour, and N1c pale yellow.
Many explosives of this type are in use in different countries. On the old British Permitted List were Ammonite, Westfalite, Bellite and Roburite amongst others. Those now on the List contain ammonium or sodium chloride to enable them to pass the Rotherham Test, e.g. the later Ammonites, Bellite Nos. 2 and 4, Faversham Powder and Negro Powder.

GIANT COAL-MINE POWDERS are American coal-mine explosives on the Permissible List. No. 5 is an ammonium nitrate explosive, whereas Nos. 6, 7 and 8 are low-grade dynamites mixed with hydrated salts.
GIANT POWDER is a name given in America to dynamite. No. 1 is a kieselguhr dynamite containing about 75 per cent. of nitroglycerine. Many varieties, however, do not contain kieselguhr, but consist of nitroglycerine mixed with wood pulp, sodium or potassium nitrate, resin, sulphur or other combustible matter. The nitroglycerine is sometimes gelatinised with collodion cotton, or in the “Extra” varieties is partially replaced by ammonium nitrate.
GLONOINE was an early name for nitroglycerine.
GLUECKAUF.—A German explosive of the Grisounite type consisting of ammonium nitrate and vegetable meal, to which might be added any of the following: sugar, resin, fatty oil, potassium nitrate, sodium nitrate, dinitro-benzene, ammonium oxalate, copper oxalate, copper nitrate ammonia, or sodium chloride. It was used for a time by several potash mines; was given up again by most of them.

GRANATFUELLUNG (i. e. Shell-filling) is a name given by the Germans to certain high explosives used for filling shell. Granatfuellung C/88 is picric acid, and C/02 is trinitro-toluene. See Fuellpulver. Other substances used in German shell and bombs are trinitro-anisole, dinitro-benzene, hexanitro-diphenylamine and hexanitro-diphenyl sulphide, otherwise picryl sulphide.
GRISOUNITE.—A French coal-mine explosive. See FAVIER Explosives.
GRISOUTINE or GRISOU-DYNAMINE is the only explosive except Grisounite allowed in the more dangerous French coal mines. It consists of ammonium nitrate mixed with blasting gelatine. As the State monopoly does not extend to explosives containing nitroglycerine, it is made by private firms, but the compositions are regulated by the “Commission des Substances Explosives,” which in 1911 resolved that they should be uniformly as follows—
Couche Couche au Salpêtre. Roche. Roche au Salpêtre.
Nitroglycerine 12 12 29 29
Collodion cotton 0·5 0·5 1 1
Ammonium nitrate 87·5 82·5 70 65
Potassium nitrate — 5 — 5
The calculated temperatures of explosion of the Grisoutines couches are below 1500°, and those of the Grisoutines roches below 1900°. The addition of 5 per cent. of potassium nitrate is found to increase the safety.
There are a number of explosives of this type made in other countries also, but they usually contain small proportions of combustible substances such as wood meal, and nitro-bodies such as trinitro-toluene. Of British explosives of this type, mention may be made of Monobel, Super-Excellite and Monarkite. German explosives of this sort include Salit, Tremonit, Donarit, Ammon-Karbonit and Astralit.
On the Belgian list of Explosifs S.G.P. is Grisoutine II., which is identical in composition with Dynamite anti-grisouteuse V.

GUNPOWDER. See BLACK POWDER.
*HALAKITE attracted public attention out of all proportion to its merits, of which it possessed none, in consequence of the extravagant claims made on its behalf by its “inventors” and their dupes. Early in 1917 the British Government caused an inquiry to be held, and the case for the explosive collapsed in a ludicrous manner. According to patent specification, No. 685 of 1915, the basis of the explosive was an admixture of lead nitrate with glycerine and other substances, and under the working conditions the glycerine was said to react with the nitrate to form a nitro-compound, which, of course, is not true. The substance actually submitted to the British and French authorities consisted of cordite mixed with lead nitrate, barium nitrate and lead chromate. This was stated by the promoters to be equally effective as a high explosive and a propellant! See “Interim and Final Reports of the Army Council (Halakite) Inquiry,” Cd. 8446.
HALALIT.—A German blasting explosive made by Nahnsen, containing not more than 65 per cent. of potassium perchlorate, ammonium nitrate, and not more than 32 per cent. of nitrated toluene, of which not more than 20 per cent. must be trinitro-toluene.

HASSIA-CHLORAT is an explosive that was introduced in Germany during the War. It consists of 65 per cent. potassium chlorate and 35 per cent. combustible, and it is claimed that the large proportion of the latter not only makes it a mild explosive, but also renders it comparatively insensitive. It is also called Spreng-chlorat.

HUDSON’S EXPLOSIVE.—A stiff blasting gelatine made by incorporating nitroglycerine and collodion cotton together with the aid of acetone. It was tried in America in 1889 for filling shell, but is not used now for this purpose.
HYGRADE COAL POWDER NO. 2 is an American coal-mine explosive on the Permissible List. It is a nitroglycerine explosive.
*IDEAL POWDER is a shot-gun powder made by Nobels.
IMPERIALITE is of no practical importance, but is interesting, as its history is that of the explosive one meets in the comic papers. The Marquis R. Imperiali had large private means and some knowledge of chemistry. He took out patents for a number of explosive mixtures and built a small factory in N. Italy, which started work in 1911. An explosion occurred the first day and killed five of the fifteen workers. Imperiali escaped and re-erected his factory. The day after it was restarted it blew up again and Imperiali was killed. The composition of the explosive that was being made is not known, but several of the mixtures for which Imperiali had taken out patents were decidedly dangerous.
*INDURITE was a smokeless powder patented by C. E. Munroe in 1893. It was made by incorporating guncotton with nitro-benzene to a hard mass. It was used for a time in the American Navy. Samples made in 1891 were still stable apparently in 1914, but some cases of instability occurred and it was given up.
INGÉLITE is the same in composition as ANTIGEL DE SÛRETÉ.
*Poudre J.—A French smokeless powder used for shot-guns and revolvers. Its composition is—
Nitrocotton 83

It is incorporated with the aid of ether-alcohol and pressed into strips, which are cut into cubes and then converted into grains of irregular shape. The fine siftings are used for revolver and practice ammunition.
JUDSON POWDER.—A mild blasting explosive used in America. It is a sort of crude gunpowder coated with nitroglycerine to increase the violence of the explosion. The percentage of nitroglycerine may vary from 5 to 20, but is generally near the lower limit. Judson Powder R.R.P. has the composition—
Nitroglycerine 5 Nitroglycerine 5
Sodium nitrate 64 or Sulphur, coal and resin 35
Sulphur 16 Sodium nitrate 60
Cannel coal 15
The sodium nitrate is mixed with the combustibles and the mixture is heated beyond the melting-point of the sulphur and resin. The slightly porous mass thus formed is then coated with nitroglycerine. The explosive is fired with a priming cartridge of dynamite. The following four grades are made by the Du Pont Co.—
FFF 20 % nitroglycerine

OXYLIQUIT is a blasting explosive consisting of liquid oxygen absorbed in some porous combustile material, such as absorbent cork, soot or kieselguhr mixed with petroleum. It was discovered in 1895 by Prof. F. C. Linde, and was tried on a large scale in 1899 in the construction of the Simplon tunnel. It is very cheap, and is safe in the case of a missfire, because in about half-an-hour the oxygen has all evaporated off and the charge becomes inexplosive. On the other hand, it is necessary to have the air liquefying plant near the scene of operations, and the charge must be fired soon after charging. These disadvantages prevented the adoption of the explosive, but during the War fresh trials were made in Germany in consequence of the scarcity of nitrates.
Liquid oxygen explosives are now used on a considerable scale by the Germans for military, as well as civil blasting operations. The name Oxyliquit, however, seems only to be applied to them when the explosive is made in the manner and with the plant of the Linde Company. See also Marsit.
PANCLASTITE.—A Sprengel explosive made by mixing liquid nitrogen peroxide with carbon bisulphide, nitro-benzene or nitro-toluene. It was proposed in 1881 by Turpin, and was tried by Germany for filling shell, the two constituents being contained in separate glass containers, which were broken by the shock of discharge. It was not adopted there on account of the inconvenience of dealing with a liquid which gives off poisonous fumes. It is a powerful and violent explosive, and is probably the same as the “Turpinite” about which sensational statements were made in the press early in the War.
