[modeleng] Re: Alumin(i)um was RE: Re: O/T Disposable Propane bottles

Are these also known as laundry soda -- the item called for in the formulas 
for electrical removal of rust?

At the time it was done, the largest non-nuclear piecetime explosion in the 
world was made using ammonium nitrate in east Tennessee southwest Virginia 
to get material for construction of South Holston Dam (which, incidently was 
the reason I grew up in east Tennessee).  Geological conditions where they 
wanted to build the dam would not support the concentrated weight of a 
concrete dam, so South Holston was built with a pure red clay core and 
limestone boulders on either side of the clay core.  And the boulderes 
formerly existed as a mountain, until said ammonium nitrate explosion.
