The simplest way to produce powder from minerals is to scratch a sharp edge of a specimen against a rough & hard ceramic plate. You may try a pyrite specimen on the table to see if it is correct.
Ice – the solid form of water, H2O
Olivine – a silicate, (Fe, Mg)2SiO4
olivine crystals in the basalt
It is the first mineral crystallized out from the molten magma.
