'AN Wax' is an
explosive composition that consists of
Ammonium Nitrate,
floor wax, and sometimes
aluminum powder. Compared to
TNT, it is not very powerful as far as
brisance and is rated at .08 TNT equivelence. It is similar to
ANFO but easier to detonate. Ammonium Nitrate is very
hygroscopic(meaning it readily absorbs moisture from the air), which can render it useless as an explosive. However, the addition of wax protects the AN from absorbing water to an extent. It takes a large
detonator or even a powerful booster charge to detonate it. The addition of Aluminum powder is known to sensitize the mixture and add blasting power.
