Mohs Scale of Mineral Hardness. In 1812 the Mohs scale of mineral hardness was devised by the German mineralogist Frederich Mohs (1773-1839), who selected the ten minerals because they were common or readily available. The scale is not a linear scale, but somewhat arbitrary.
Below is the list of 12 Hardest Mineral in the World. 10. Talc. Mohs hardness– 1 Chemical formula– MgSi4O10(OH)2 Absolute hardness– 1. Talc is a mineral composed of hydrated magnesium silicate. On the scale of 10 hardest minerals, talc is listed as 1 on the Mohs hardness scale. ... Many recent studies show that the Diamond is no more the ...
All minerals are in this scale, since talc is the softest known mineral and diamond is the hardest. Suppose a mineral scratches fluorite, but not apatite, then it has a hardness between 4 and 5. Hardness is usually rounded off to the nearest half number.
What Are Some Examples of Silicate and Nonsilicate Minerals? Some examples of silicate minerals are quartz, talc, tourmaline and garnet; some examples of nonsilicate minerals are calcite, gypsum, alabaster, and the native elements copper, gold and silver. A negatively charged silicate ion, or anion ...
Original Mohs Scale of Mineral Hardness. ... Hardness: Mineral: Associations and Uses: 1: Talc (Softest) Talcum powder. (can be scratched by a fingernail.) ... nor is the difference between Calcite and Fluorite similar to the difference between Corundum and Diamond. Hardness is used in a rough way to inform mineral identification in the field ...
The softest mineral, talc, has a Mohs scale rating of one. Diamond is the hardest mineral and has a rating of ten. Softer minerals can be scratched by harder minerals because the forces that hold the crystals together are weaker and can be broken by the harder mineral.

In Australia, the largest gold nugget in the world was found in 1869. It weighed 156 pounds! Gold is one of the most valuable minerals.
The Mohs hardness scale is based 10 reference minerals, from talc the softest (Mohs hardness of 1), to diamond the hardest (Mohs hardness of 10). It is a relative, or nonlinear, scale. A hardness of 2.5 simply means that the mineral is harder than gypsum (Mohs hardness of 2) …
The hardness of a mineral is a good tool you can use to help identify minerals. In 1812, a man named Fredrich Mohs invented a scale of hardness called Mohs Scale which is still used today. He selected ten standard minerals, and arranged them in order of increasing hardness. Talc is the softest and diamond is the hardest. Get a Price
All conceivable minerals fit in this scale, since Talc is the softest known mineral and Diamond the hardest. To demonstrate how to use the scale, understand the following example: Suppose a mineral scratches Fluorite, but not Apatite, then it has a hardness between 4 and 5.

Talc Talc is the softest mineral, demonstrated by its position at the bottom of Mohs' Scale of Hardness with a relative hardness value of 1. It has a soapy, greasy feel. Talc is formed by the hydrothermal alteration of ultrabasic rocks, or low grade thermal metamorphism of siliceous dolomites.

What is talcum powder? Talcum powder is the refined, powdery form of the softest mineral on earth: talc. Talc is an "inert" ingredient, meaning it does not generate a chemical reaction when ingested or used on the skin. People have taken advantage of its natural smoothness, safety and adsorbency since ancient Egyptian times. 1
Diamond is actually over four hundred times harder than talc. The Mohs scale is only one way to classify mineral hardness. A simpler method, often used by geologists during field work, is to classify minerals as harder or softer than a steel knife or a fingernail.
For a example Talc is the softest mineral so the number is one and the hardest mineral is the diamond which is number 10 so it would be the hardest. The higher the number is on the scale the harder it is. Some of the minerals you can scratch with your finger nails, with Talc you can scratch with your fingernail and the same with Gypsum.
Talc is an important industrial mineral. Its resistance to heat, electricity and acids make it an ideal surface for lab counter tops and electrical switchboards. It is also an important filler material for paints, rubber and insecticides.
Minerals with metallic bonds. a. Conduct heat. b. Conduct electricity ... Talc. II. RESULTS OF BONDS. A. Polymorphs--same chemical composition but different crystal structures e.g. diamond and graphite. B. Compound--substance composed of more than one type of atom; a group of elements. 1.
Minerals and precious stones: Earth's jewels. ... Some minerals like talc are soft and can be scratched with a fingernail. Other minerals are the opposite. A diamond, for example, is so hard that it can only be scratched by another diamond! Transparency.
The diamond is the hardest substuance on the MHos Scale and Talc is the softest.
Diamond is the hardest mineral. If you were to throw a diamond on the ground it wouldn't chip or come close to breaking. If a diamond is scratched up against a window the window would break that's how strong a diamond is. Talc is the softest mineral. Talc is what baby powder is made of.
