Talc is a mineral that results from the metamorphism of magnesian minerals such as serpentine, pyroxene, amphibole, and olivine, in the presence of carbon dioxide and water. This is known as "talc carbonation" or "steatization" and produces a suite of rocks known as talc carbonates.
For example, your fingernail can scratch the minerals talc and gypsum, with a hardness of 2 or lower. A copper penny can scratch calcite, gypsum, and talc. A common misunderstanding of how to identify a diamond is that it will scratch glass. While this is true, other minerals can scratch glass too as long as they have a hardness > 6.

Mohs hardness scale was devised in 1812 by Friedrich Mohs and has been the same ever since, making it the oldest standard scale in is also perhaps the most useful single test for identifying and describing minerals.. You use the Mohs hardness scale by testing an unknown mineral against one of the standard minerals.
Talc, common silicate mineral that is distinguished from almost all other minerals by its extreme softness (it has the lowest rating [1] on the Mohs scale of hardness). Its soapy or greasy feel accounts for the name soapstone given to compact aggregates of talc and other rockforming minerals. Dense aggregates of highpurity talc are called ...
Identifying Rocks and Minerals Using the Mohs Hardness Test . Grades K – 12 . Introduction. Some minerals are harder than others. The hardness of a mineral is a good tool for helping to identify it. You can also use other physical properties of an unknown mineral specimen such as color, luster, streak, and specific — gravity — to help ...
Apr 12, 2017· German mineralogist Frederich Mohs'' 1812 Hardness Scale associated a hardness score with 10 common minerals, with diamonds scored as the hardest, at 10, and talc the least hard, at 1. Minerals with higher numbers can scratch any mineral with a lower number, and lower numbers can never scratch a higher numbered mineral.
Identifying Rocks and Minerals/Hardness Wikibooks, open books ... To test the hardness of a specimen take it and try to scratch it with the first rock your in your hardness kit, Talc, if it is scratched then the rock your testing then it is ...
In a coarse grained rock, identifying the individual minerals allows you to identify the rock. If the rock is finegrained, it''s harder to interpret the results. The hardness of finegrained rocks tends to reflect the average hardness of the minerals in them. Shales are made mostly of clay and tend to be soft.

Talc. Talc is a common silicate mineral that is distinguished from almost all other minerals by its extreme softness (it has the lowest rating [1] on the Mohs scale of hardness). Its soapy or greasy feel accounts for the name soapstone given to compact aggregates of talc and other rockforming minerals.
Talc is the softest known natural mineral. It is given the designation of 1 on the Mohs hardness scale, which gauges the relative hardness of a substance, usually an unknown mineral. The hardest known natural mineral is diamond, which is designated 10 on the Mohs hardness scale.
Mohs'' scale of mineral hardness is named after Friedrich Mohs, a mineralogist. Mohs invented a scale of hardness based on how one mineral scratched another. Rocks are made up of one or more minerals. According to the scale, Talc is the softest: it can be scratched by all other materials.
Mineral Hardness . The hardness of a mineral is a way of describing how easy or difficult it is to scratch the mineral. It is used, in combination with the other physical properties, to help identify a mineral specimen. In mineral books, hardness is shown using the letter "H." An example of this is "Talc, H1".

Talc is known for being the softest mineral on earth. It is number 1 on the Mohs hardness scale, and can be easily scratched by a is not commonly seen in collections, as it is usually uninteresting and fairly common, although a few deeply colored and .
diamond with a hardness of 10. It is composed of microscopic platelets, and the bonds holding the platelets together are very weak. This enables the platelets to slide by one another and results in the soft and greasy feel of talc. Talc is also used as a term to describe a rock that contains the mineral talc. Other names for talcrich rocks are ...
A form of talc known as "soapstone" is also widely known. This soft rock is easily carved and has been used to make ornamental and practical objects for thousands of years. It has been used to make sculptures, bowls, countertops, sinks, hearths, p...
Physical Properties of Talc carbonate. Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Talc carbonate like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it.
Mohs Vickers hardness comparison: This chart compares the hardness of index minerals of the Mohs hardness scale (an integer scale) with their Vickers hardness (a continuous scale). Mohs hardness is a resistance to being scratched, while Vickers hardness is a resistance to indentation under pressure.
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.
