=ASTRALIT.=--An ammonium nitrate explosive containing a little

blasting gelatine, made by the Dynamit A. G. Nobel of Hamburg. It has

been used largely in Germany for a variety of purposes.

Astralit I and II are defined as consisting of ammonium nitrate,

charcoal, vegetable meal, not more than 15 per cent. of aromatic

nitro-bodies not more dangerous than trinitro-toluene, not more than

4 per cent. of blasting gelatine; also paraffin oil.

Astralit IV consists of ammonium nitrate, not more than 10 per cent.

of aromatic nitro-bodies not more dangerous than dinitro-naphthalene,

vegetable meal, and not more than 4 per cent. of blasting gelatine.

Astralit V, which has been introduced recently, contains up to

10 per cent. of potassium perchlorate in addition to ammonium

nitrate, also vegetable meal, not more than 16 per cent. of aromatic

nitro-compounds, and not more than 4 per cent. of nitroglycerine.

Gelatine-Astralit is a gelatinised or powdery mixture of the nitrates

of ammonium and sodium (or potassium), not more than 50 per cent. of

dinitro-chlorhydrin, not more than 5 per cent. of nitroglycerine, not

more than 2 per cent. of collodion cotton, vegetable meal, aromatic

nitro-bodies such as nitro-toluenes or nitro-naphthalenes, but not

more than 4 per cent. of trinitro-toluene; also hydrocarbons.

Wetter-Astralit is a coal-mine explosive, and differs from Astralit

in that part of the ammonium nitrate is replaced by sodium chloride.

Wetter-Gelatine-Astralit is also a coal-mine explosive, and differs

from Gelatine-Astralit in that it contains also fatty oils and

neutral salts, such as potassium chloride, sodium chloride or an

oxalate.
