yes, minerals can only be scratched by other minerals with hardness equal or greater.
thus this explains why a diamond can be cut and "polished" by dust or smaller diamonds
The items at the level of four are Stellite 6, Titanium, and Glass.
The Mohs scale of hardness goes from 1-10 in order of relative hardness. Knowing that, you know that anything more than 6 will be harder than 6 because that is the definition of "more than."
a diamond can scratch talc
Yes
hardness.
A mineral is a naturally occurring solid formed throughgeological processes that has a characteristic chemical composition, a highly ordered atomic structure, and specific physical properties. Minerals in composition from pure elements and simple salts to very complex silicates with thousands of known forms The study of minerals is called mineralogy. A mineral is an element or chemical compound that is normally crystalline and that has been formed as a result of geological processes. Physical properties commonly used are: Crystal structure and habit: See the above discussion of crystal structure. A mineral may show good crystal habit or form, or it may be massive, granular or compact with only microscopically visible crystals. Hardness: the physical hardness of a mineral is usually measured according to the Mohs scale. This scale is relative and goes from 1 to 10. Minerals with a given Mohs hardness can scratch the surface of any mineral that has a lower hardness than itself.
It's wind.
Mineral spirits should evaporate rather quickly. Scoop out any residue manually.
No. It can vary from the visible color of the mineral and, since visible color of them ineral is not a reliable indicator of type, it is important to learn to use streak, (along with other factors), to correctly identify a mineral.
According to the Mohs scale of hardness, Diamond has a hardness of 10 and Quartz has a hardness of 7. Any mineral with a hardness greater than 7 can scratch quartz and diamond can scratch any mineral with a hardness less than 10. Corundum (hardness of 9) and Topaz (hardness of 8) are two examples of minerals that can scratch quartz but not diamond.
According to the Mohs scale of mineral hardness, quartz (7) will not scratch any mineral with a higher number on the scale. Corundum is listed at 9. Therefore quartz will not scratch corundum, but corundum can scratch quartz.
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 !
Using the Mohs Mineral Hardness scale, calcite has a hardness of 3. Hence anything with a hardness of 3 or above can scratch calcite (i.e...quartz and fluorite).
A peridot could scratch any mineral with a Mohs hardness of 6.5 or less. Click on the link below for information on the Mohs hardness scale.
False. A mineral can only scratch itself or minerals equal in hardness or softer than it.
Yes. Any metal or mineral will scratch itself and anything softer than it on the hardness scale.
Fluorite is unable to scratch feldspar, quartz, corundum, diamond, or any other mineral with a Mohs hardness greater than 4.
Any mineral with a Mohs hardness of 3 or above. Diamond, for instance.
It would depend on how loosely the sandstone was cemented. Some sandstone can be crumbled in your clenched fist, and some are extremely hard.
Talc can scratch Talc , although Talc's hardness varies it is considered a soft mineral, that can even be scratched with a finger nail. Any mineral or material with a hardness equal to or greater than 1 on the Mohs hardness scale will be able to scratch talc. Talc is the softest mineral listed on the Mohs scale, listed as a 1 on the scale which is graded from 1 through 10, with 10 being the hardest (diamond).
A diamond has a hardness of 10 on a scale of 10 known as Mohs Hardness Scale. A diamond can scratch any other mineral. It isn't the only mineral that can scratch glass thou, quartz, corundum,garnet, among others
