Freezing dynamite made the nitroglycerine more stable and safer, so it was, for example, often shipped packed in ice. Dynamite’s freezing temperature is only 11 degrees Celsius, so freezing it was not difficult. However, its low freezing temperature also meant that dynamite could become frozen unintentionally in cooler weather, especially in the simple buildings and shacks in which historical miners often stored it. Dynamite had to be thawed before using, but careless thawing methods caused many historical accidents. There are/were special thawing containers, but some people improvised.
