Did you know?

  • Stibnite is the main ore of antimony, and its powder was among the ingredients of eye paint in the ancient world.
  • Japan's Ichinokawa mine produced giant stibnite crystals so spectacular that museums around the world display them.

Could you guess it from clues?

WildGuessr picks a secret animal, plant, fungus, stone, prehistoric creature or space object and you ask yes-or-no questions about it, such as its group or where it grows. The fewer clues you need, the more points you score.
