It shatters the coal less than high explosives do. =BOMLIT.=--A German potassium perchlorate blasting explosive made by Wolff et Cie. at Walsrode. It contains also ammonium nitrate, trinitro-toluene and guncotton. Other ingredients that may be present are potassium and sodium nitrates, starch meal, vaseline, naphthalene and other hydrocarbons, charcoal and castor oil. =BRITONITE.=--A coal-mine explosive of the Carbonite type, made by the British Explosives Syndicate, Ltd., Pitsea. The original composition passed the Woolwich Test and was on the list of Permitted Explosives, but on the introduction of the Rotherham Test it became necessary to add ammonium oxalate or sodium chloride. Nos. 2 and 3 were on the Permitted List, but have now been repealed. No. 2.

They contained the same constituents as Bobbinite, which superseded them, but in different proportions.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.
