BAVARIT.—A German coal-mine explosive similar to [Grisounite]. It contains 90 per cent. of ammonium nitrate together with nitrated naphthalene; charcoal may be added.

BELLITE is essentially a mixture of ammonium nitrate and metadinitro-benzene. It has been used extensively as a coal-mine explosive, and was patented by C. Lamm of Stockholm in 1885. Two varieties passed the Woolwich Test and were on the old Permitted List—

  No. 1.  No. 3.
Ammonium nitrate83·5 93·5
Dinitro-benzene16·5 6·5

No. 1 contains just enough oxygen for complete combustion, and No. 3 contains a large excess of oxygen. To enable the explosive to pass the Rotherham Test sodium chloride has been added. There were four varieties on the present Permitted List, but all except the following, No. 1, have been repealed—

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.
