Heavy particles. CNCT is stronger than stone and is very rigid, it can be built on top of itself into straight columns without crumbling. It is the only powder to do this. Nothing can move through CNCT, no matter how heavy - including DEST! DEST can melt it, but can't get through! However, it can fall down through gasses and liquids.

CNCT can be created (1/25000 chance) by taking molten ROCK and putting it under between 25 and 50 pressure.
