Flint? Rock, metal or maybe a mixture?

    Hi,

    Without getting into the details, I am not an expert in physics or chemistry or sciences in general.

    But is there some kind of a hard material that if scrapped off a rocky surface would create sparks?

    I'm thinking if its possible to mix with one of those chemicals and create a material that will make colourful sparks.

    The idea would be to create sparks with out damaging the main body (not our material) with too many scrapes.

    Thanks!
