[Cold Heart]

I remember reading a story in grammer school (awhile back)about a company hauling dynamite on a horse drawn wagon.
It was winter and the thinking at the time was that it was dangerous to let the dynamite get cold (freeze) so they had hot bricks under the tarp covered boxes of dynamite. The story went that the teamster got stuck in the snow and the dynamite did freeze. They found out that the dynamite was more difficult to ignite. That was new dynamite.

As dynamite ages, the nitroglycerin interspersed in the clay coagulates and weeps out, then becomes very dangerous. 25 years is old. I guess cold isn't good in old stuff.

Not an expert but that is what I remember.

I know that glycerin mixed with bird crap and fruit loops makes some mighty powerful explosives. We did it in high school chemistry club.(when it was still PC to learn stuff)

The biggest explosion though was a dust explosion we created under a barrell, using graphite.
