AN is extremely deliquescent; perhaps the sulphate was for that? Removing chunks with dynamite is trying rather hard for a Darwin award. When I was a teen I would save the instant-cold packs after soccer games, and recrystalize the AN within. It melts and gives off bubbles but I never collected enough N20 nor did it detonate.

You need a lot of heat to detonate AN, but I have never failed to detonate it. Perhaps your stuff was contaminated with water or stabilizer, or perhaps you need a better flame. --digsig James A.

No, it was specifically required as a desensitiser by the European nitrogen cartel, since they felt the pure nitrate was too dangerous for processing into fertiliser.

As I said, at the time its explosive properties weren't known so this wasn't unreasonable. There are numerous stories of multi-thousand-ton ammonium nitrate piles burning for hours without exploding (Oppau was the first time there was any significant explosion involving it). Even after Texas City, there were cases of (embarrassed) firefighters watching warehouses full of ammonium nitrate quietly burn to the ground without incident. Peter.
