Welcome to the depths of this abandoned quarry, as we explored this timeless corridor, one detail stood out: a chemical formula written directly on the wall.
CaC₂ + 2H₂O → C₂H₂ + Ca(OH)₂
That’s the reaction inside carbide lamps. Calcium carbide reacts with water to produce acetylene gas, which burns with a bright, warm flame. It feels raw and full of character.
