We had some of that stuff, we couldn’t light it on fire, it was completely inert.
We mixed it with fuel oil, lit it on fire, it didn’t go off.. it just burned
Then we put an explosion on it and it blew up a stump.
I don’t buy all this story because I never saw it demonstrated from first hand experience.
Only thing we didn’t try was putting the explosion against the plain ammonia nitrate. But since it was inert when we were working with it, we would have expected it just to produce a cloud of dust.
We were doing this by the way as part of a demonstration I was assisting on for how safe these explosives were for mining companies at a mining festival. I pretty much just did the hauling and the mixing why the explosives guy did all the actual demonstrations.
Heat a decent amount to 200c and keep heating it till it hits 570c, but be at a safe distance....it will explode.
