~Bellite~ is the patent of Mr Carl Lamm, Managing Director of the Roetebro
Explosive Company, of Stockholm, and is licensed for manufacture in
England. It consists of a mixture of nitrate of ammonia with di- or
tri-nitro-benzol, it has a specific gravity of 1.2 to 1.4 in its granulated
state, and 1 litre weighs 800 to 875 grms. Heated in an open vessel,
bellite loses its consistency at 90 deg. C., but does not commence to separate
before a temperature of 200 deg. C. is reached, when it evaporates without
exploding. If heated suddenly, it burns with a sooty flame, somewhat like
tar, but if the source of heat is removed, it will cease burning, and
assume a caramel-like structure. It absorbs very little moisture from the
air after it has been pressed, and if the operation has been performed
while the explosive is hot, the subsequent increase of weight is only 2
per cent. When subjected to
