=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- Grisou-naphtalite-. couche. roche. N_1 a. N_4. N_1 b. Ammonium nitrate 95 90 91·5 86·5 Potassium nitrate -- 5 -- 5 Dinitro-naphthane -- -- 8·5 8·5 Trinitro-naphthalene 5 5 -- -- Tetryl -- -- -- -- For mines free from Grisou-tetrylite-couche. fire-damp, etc. N_1 c. Ammonium nitrate 88 87·4 Potassium nitrate 5 -- Dinitro-naphthane -- 12·6 Trinitro-naphthalene -- -- Tetryl 7 -- The Grisounites-couche are used in the coal seams as they have theoretical temperatures of explosion of 1500° or less, but N_1 a has been replaced to a considerable extent by N_4, 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. N_1 b is dyed rose colour, and N_1 c 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. On the Belgian list of Explosifs S.G.P. is Favier II bis-- Ammonium nitrate 77·6 Dinitro-naphthalene 2·4 Ammonium chloride 20 Charge limite More than 293 grammes. =FAVORIT.= See =KORONIT.= =*FELIXITE= is a smokeless shot-gun powder introduced in 1906 by the New Explosives Company. It is a fibrous 42-grain bulk powder, and, according to an analysis published in “Arms and Explosives,” 1917, p. 76, has the composition--
