  • @ Op -Neandertal uses for manganese dioxide

    When they sprinkled that powder on a pile of wood, it lowered the temperature needed to initiate combustion to 250°C, making it much easier to start a fire, they report today in Scientific Reports. (Untreated wood failed to ignite at temperatures up to 350°C.)

    Manganese dioxide is well known as a catalyst, so it is quite possible this was discovered when trying different fire making methods, and materials.
    A dusting, would also make an existing fire burn more fiercely – so the effect should be fairly obvious.
    Hunter-gatherers (and chimps) are usually very perceptive about resources in their territory.
