The hardness of a rock is determined by scratching it with a harder material.
The property of rocks that can be determined by whether they scratch glass is their hardness. This is measured on the Mohs scale, which ranks minerals based on their ability to scratch one another. If a rock can scratch glass, it indicates that its hardness is greater than that of glass, which has a hardness of about 5.5 on the Mohs scale. Conversely, if it cannot scratch glass, it is likely to be softer than this standard.
Rock types are determined by the mineral composition and texture of a rock. Rock names are often based on the predominant mineral present in the rock or the location where the rock is found. Geologists use various classification systems to categorize rocks based on their characteristics.

It is best determined by radiometric dating techniques which measure the decay of radioactive elements.
The texture of a rock is determined by the rate it takes the molten to cool to form the rock.

no
That depends what you scratch it with, what material the rock is made from, and how much force you apply when scratching.

If two rocks cannot scratch each other, then they would have to be of equal hardness. A harder rock can always scratch a softer rock.
That would be Talc.
diamond
it can get scratch by a diamond
will 0000 rock wool scratch windsheild glass
you can crush it good or you can scratch it on something hard
