Mauxite metal bars explode

[Paineframe]

I accidentally hit a pile of mauxite bars with a bar of mauxite, and the resulting explosion (helped along by a few pieces of plasmastone lying around) almost completely obliterated the arc smelter room but heavily damaged the cold loop room, engineering storage, the cargo area, and even took out a couple of QM belts. Not only is it explosive, but it makes tremendously powerful explosions.
