A clear mineral that exhibits conchoidal fractures and can scratch glass is quartz. Quartz has a hardness of 7 on the Mohs scale, making it capable of scratching glass, which has a hardness of about 5.5. Its characteristic conchoidal fractures create smooth, curved surfaces when broken. Commonly found in various environments, quartz is one of the most abundant minerals in the Earth's crust.
it is hardness
Diamond is the hardest mineral and is the only one that can scratch corundum. but in my opinion corundum will scratch corundum any mineral of the same hardness will scratch the other !
false a mineral can not scratch any mineral harder than itself
Halite can scratch gypsum.
Diamonds are proven to scratch all minerals including itself.
The mineral that fits these descriptions is obsidian. Obsidian is a natural volcanic glass that can scratch glass, has a nonmetallic luster, typically exhibits conchoidal fracture, and is usually a dark color, such as black, dark green, or dark brown.
A harder mineral will scratch a softer one.
You can tell if a mineral can scratch another mineral by performing a scratch test, where you use the hardness scale to compare the minerals. If the mineral you are testing can scratch the other mineral, then it has a higher hardness on the scale.

A diamond is the only material that cannot be scratched by any other than itself.
Halite can scratch gypsum.
True. In general, a mineral can scratch any mineral that is softer than itself according to Mohs Scale of Mineral Hardness. This means that a mineral with a higher number on the scale can scratch a mineral with a lower number.
The mineral that fits this description is garnet. Garnet has a hardness of 6.5-7.5 on the Mohs scale, meaning it can scratch glass. It has a non-metallic luster, exhibits fracture rather than cleavage, and is commonly found in a dark red color.
False. A mineral can only scratch itself or minerals equal in hardness or softer than it.
When a mineral can scratch another mineral, it means that the mineral is harder than the mineral it can scratch. Hardness is a measure of a mineral's resistance to being scratched, with the Mohs scale commonly used to rank minerals based on their hardness.
