Now if you could lay your hands on some anhydrous hydrazine, and used that instead, you could filter out the clay and use the finished liquid product directly. This would be "Astro-Lite" the most powerful non nuclear explosive available.
Beware of the fumes when mixing the ammonium nitrate and the anhydrous hydrazine, the gas can kill you.
So endith todays lesson.

Glad you are on the side of right, GtG
Beware of the hydrazine itself. It dissolves human flesh.
Ask any ME-163 pilot who had it get loose in his cockpit.
