It is talc
it is a geological scale that measures the hardness of different minerals. Talc being the softest and a diamond being the hardest.
a scale that ranks ten minerals from softest to hardest
I really don't know what the hardness of Cinder is but by testing it I think it has a hardness of 4
The scratch table is called the Mohs Scale of Mineral Hardness and measures the hardness of minerals in relation to the known hardest (diamond) and softest (talc) minerals.
