      the fires they had were probably not hot enough to melt sand into glass without some additives.

      Instead, it’s a fine particulate that can be heated way hotter than water, and because the grains are small enough they will disperse over a large area causing burns to people in a large area below

      Ever get sand stuck in your clothes?

      Imagine that at or near the temperature of boiling water.

      Sand retains heat pretty well, flows quickly, and is a bitch to get out. Not only that, but it’s great at slipping in where its recipients wouldn’t want it - down the collar, under a mail shirt, through the visor of a helmet, you name it. You’ll be covered in serious burns, third-degree even, potentially, if you get caught under it, and sand is dirt-cheap.
