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 nitrocotton18·6

Nitrates of potassium and barium  28·0
Vaseline6·0
Volatile matter1·4

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—
