How hard is iridium?
Iridium is a 6.5 on the MOHs scale. This makes it about as hard as glass, silicon, or iron pyrite. It is harder than titanium or manganese, but softer than quartz or vanadium.
What is the harness of a mineral if it scratches a penny but will not scratch glass?
Google "Mohs hardness scale". This is a relative hardness scale which compares one mineral's hardness to another. (It is between 3.5 and 5.5 on the Mohs hardness scale)
What scale is used to find a mineral's hardness?
the mohs hardness scale
If a mineral is a 6 on the mohs scale what can it be scracted by?
A mineral with a hardness of 6 on the Mohs scale can be scratched by anything harder than a 6, such as minerals with a hardness of 7 or higher. It will not be scratched by minerals with a hardness of 5 or lower.

Glass is about 6-6.5
How hard is glass on the Mohs hardness scale?
Glass is about 6-6.5
Can apatite scratch glass?
Probably not as apatite has a Mohs hardness of 5.0 and window glass lies between 5.0-6.0 on the Mohs scale. A higher Mohs number cannot be scratched by a lower number.
What is glass on moh's scale?
Glass is around a 5.5 on the Mohs scale of hardness. This means that materials with a higher value on the scale can scratch glass, while those with a lower value cannot.
Why can a diamond scratch chalk?
No. Hardness is measured on the Mohs Scale, named after German Friedrich Mohs. On this scale Talc (the softest) measures 1, while Diamond (the hardest) measures 10. Glass has a Mohs' scale hardness of around 5.5, so anything above that will have the ability to scratch glass. For example, quartz (Mohs 7), hardened steel (Mohs 8), corundum (rubies and sapphires, Mohs 9),or diamond (Mohs 10). The Mohs scale is purely an ordinal scale, expressing relative hardness in a simplistic way. Carborundum (Mohs 9) is twice as hard as Topaz (Mohs 8), but diamond (Mohs 10) is four times harder than arborundum.

What is scienctific reason that diamond can cut glass?
