Mica
Hardness is the measure of how easily a mineral can be scratched.
yes because it contains ethonal and that lights really easily
Spar
Theoretically yes, but it is quite implausible. Silicon forms less stable structures than carbon and silicon compounds would be solid at standard conditions and would, therefore, be quite hard to use by organisms.
Obsidian because it's the only mineral that is the blackest of well......black! Anyway it's black I mean Obsidian (\_/) (o.o) (___)o
Mica
It contains more natural ingredients than other makeup which may contain many synthetic chemical ingredients. Mineral foundation also seems to not sink into pores as easily as non-mineral makeup. Mineral makeup is also usually more environmentally and animal friendly.
Semiconductors are needed to create the transistors on chips. Silicone is a natural semiconductor. Silicon is quite cheap and easily obtained, made from regular sand which is silicon dioxide. Silicone can be grown into large crystals very easily.
Hardness is the measure of how easily a mineral is scratched.
Talc is the softest mineral and can be scratched by any other mineral.

Silicon is more semiconductor than Germanium because the characteristics of silicon can be easily modified to obtain either a p-type or n-type material.
hardness is how easily a mineral can be scratched
The term for this is "hardness".
