=KARBONIT.= See =CARBONITE=.

=KAUSOLIT.=--An ammonium perchlorate explosive, introduced about 1915 by the Stockholm Superphosphaten-fabriks A.-b.

=KENT POWDER= was a coal-mine explosive made by the Cotton Powder Co. It was of the Carbonite type and was on the Permitted List. It is now no longer “permitted.”

Date of Permit 10-2-14

Nitroglycerine 24 Potassium nitrate 32·5 Wood meal 33·5 Ammonium oxalate 10

Limit charge over 32 oz.

Power (swing of ballistic pendulum) 2·01”

=KENTITE= is a coal-mine explosive made by British Westfalite, Ltd. It was on the old Permitted List and also passed the Rotherham Test, and so is still “permitted”--

Ammonium nitrate 34 Potassium nitrate 34 Trinitro-toluene 17 Ammonium chloride 15

Limit charge 18 oz. Power (swing of ballistic pendulum) 2·64”

=KIESELBACHER CHLORATSPRENGSTOFF.= See =MIEDZIANKIT=.

=KINETIT.=--A German explosive made by gelatinising nitro-cellulose with nitro-benzene, and incorporating it with potassium nitrate and chlorate. It is somewhat sensitive to blows, etc. Early samples contained also antimony sulphide which rendered them decidedly dangerous.

=KIWIT.=--A German chlorate explosive introduced during the War. It contains not more than 77 per cent. of sodium or potassium chlorate, carbon carriers such as paraffin, naphthalene, vaseline, meal or oil, also not more than 15 per cent. of liquid trinitro-toluene, and may contain dinitro-toluene, dinitro-naphthalene, sodium chloride and not more than 4 per cent. of guncotton.

=KOHLENKARBONIT.= See =CARBONITE=.

=KOLAX.=--A coal-mine explosive of the Carbonite type formerly on the Permitted List, made by Curtis’s and Harvey--

Nitroglycerine 25 Potassium nitrate 26 Barium nitrate 5 Wood meal 34 Starch 10

=SUPER-KOLAX= was a modification of this to meet the requirements of the Rotherham Test--

No. 2. Date of Permit 1-9-13 7-4-14 Nitroglycerine 25·5 28·5 Collodion cotton -- 1 Potassium nitrate 25·5 16·5 Barium nitrate 5 5 Wood meal 29·5 30·5 Starch 7·5 9 Ammonium oxalate 7 9·5

Limit charge 30 over 32 oz. Power (swing of ballistic pendulum) 2·10 2·21”

The permits of both have been repealed.

=KORONIT=, also known as =FAVORIT=, is a German chlorate blasting explosive introduced during the War. See also Coronite.

Gesteins-Koronit (or -Favorit) contains not more than 85 per cent. of potassium or sodium chlorate, not more than 15 per cent. of nitro-bodies (but no trinitro-compounds), paraffin or fatty oils, naphthalene, vegetable meal, powdered coal, inert substances, and not more than 4 per cent. of blasting gelatine.

Kohlen-Koronit (or -Favorit) contains not more than 68 per cent. of potassium or sodium chlorate, aromatic hydrocarbons and nitro-hydrocarbons (but not more than 12 per cent. of aromatic nitro-bodies and no trinitro-compounds), sodium chloride or similar salts, paraffin or fatty oils, vegetable meal or other organic substance; not more than 4 per cent. of blasting gelatine and not more than 4 per cent. of powdered coal.

=PERKORONIT= is similar to Koronit except that it contains potassium or sodium perchlorate instead of chlorate. Part of the perchlorate may be replaced by nitrate.

=*K.S.=, =K.S.G.=--Kynoch’s Smokeless Powder. It is a fibrous bulk powder for shot-guns made by Kynochs, Ltd. The following analyses were given in “Arms and Explosives,” 1917, p. 78---
