What is the order of the minerals from the softest to the hardest?
The order of minerals from softest to hardest is: talc, gypsum, calcite, fluorite, apatite, orthoclase feldspar, quartz, topaz, corundum, and diamond. This scale is known as the Mohs scale of mineral hardness.
Why might it be important to know the hardness of different minerals?
Knowing the hardness of different minerals is important in identifying and categorizing minerals. The Mohs Scale of Hardness can help determine a mineral's resistance to scratching, which can aid in its identification. Understanding a mineral's hardness also has practical applications in industries such as construction and jewelry making.
How is the Mohs scale of mineral hardness used?
The Mohs scale of mineral hardness is used to measure the hardness of minerals by comparing their scratch resistance. It ranks minerals on a scale from 1 (softest) to 10 (hardest). By testing a mineral against the known hardness of other minerals, geologists can determine the relative hardness of an unknown specimen.
Name the 10 hardest-minerals in order.?
The hardness of minerals is measured using Mohs scale. Minerals are ranked due to their relative hardness from 1 to 10; 1 being the softest, and 10 being the hardest.10 Diamond 9 Corundum 8 Topaz 7 Quartz (porcelain - 7) 6 Orthoclase (steel file - 6.5) 5 Apatite (knife blade or nail - 5, window glass - 5.5) 4 Fluorite 3 Calcite 2 Gypsum (fingernail - 2) 1 Talc.
Why is glass marble not considered a mineral?
In order to be a mineral, substances need to have fixed internal crystalline structure. Natural glass does not.
What is the order of the minerals from the softest to the hardest?
The order of minerals from softest to hardest is: talc, gypsum, calcite, fluorite, apatite, orthoclase feldspar, quartz, topaz, corundum, and diamond. This scale is known as the Mohs scale of mineral hardness.
How does mineralogist identify the hardness of a mineral?
Minerologists identify mineral harness with a variety of tools. In order of hardness, they gnerally use their fingernails, nails, copper pennies, knife blades, glass, porcelain and other minerals such as quartz, topaz, corundum and diamond. The Moh's Hardness Scale gives a list of minerals in order of hardness with talc being the softest with a rating of "1" and diamond the hardest at a "10".

5 why is Gypsum is a 2 on Mohs hardness scale while topaz is an 8 Can gypsum scratch topaz?
No, gypsum cannot scratch topaz. Minerals with a higher number on the Moh's Hardness Scale can scratch minerals that are lower-numbered, but lower numbers can't scratch higher numbers. A mineral would have to have a number higher than an 8 on the Moh's hardness scale in order to scratch topaz.
What is the order of MOHs rating softest to hardest augite cinnabar emerald magnetite sapphire?
The order of hardness from softest to hardest for the mentioned minerals is as follows: cinnabar, emerald, augite, sapphire, magnetite.
Can a mineral scratch any mineral with a higher hardness?
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
What test is most reliable for identifying pyrite and gold?
Mineralogists often use the physical properties of minerals to identify them. The most reliable test in order to identify a mineral is the test for hardness.
Are some tests better than others for identifying certain minerals?
Yes, you can usually identify the mineral salt by its taste. However, with most minerals one would apply a series of tests, eg hardness, flame test, colour, density, streak, shape in order to identify the mineral.
What are the ten minerals of themohs scale?
The basic Moh's hardness scale consists of: 1. Talc (softest) 2. Gypsum 3. Calcite 4. Fluorite 5. Apatite 6. Feldspar 7. Quartz 8. Topaz 9. Corundum 10. Diamond (hardest)

What is the difference between vickers hardness test and brinell hardness test?
In Vickers hardness test the for used is much lighter than the force used in Rockwell hardness test, The Rockwell hardness test is the considered to be the most routinely used technique to measure the hardness of materials because of its simplicity and because it does not require specific skills in order to perform it.

The hardness of minerals is measured using Mohs scale. Minerals are ranked due to their relative hardness from 1 to 10; 1 being the softest, and 10 being the hardest.10 Diamond 9 Corundum 8 Topaz 7 Quartz (porcelain - 7) 6 Orthoclase (steel file - 6.5) 5 Apatite (knife blade or nail - 5, window glass - 5.5) 4 Fluorite 3 Calcite 2 Gypsum (fingernail - 2) 1 Talc.
