Which legendary stone is said to be of impenetrable hardness?
The legendary stone that is said to be of impenetrable hardness is the Philosopher's Stone. It is believed to have the power to transmute base metals into gold and grant eternal life.
How rocks can be identified by hardness?
The hardness of a rock is identified using Mohs Scale of Hardness. Certain rocks and minerals have a predetermined hardness level based on this scale, which uses the obvious logic that if something scratches something else, then it must be harder than that which it scratches. Likewise, if something doesn't scratch something else, it must be softer than that which it cannot scratch. Using a scale from 1 to 10, common objects can be used to determine hardness level. A fingernail, for example, has a hardness of 2.5. Any rock that can be scratched by a fingernail (talc, for example) has a hardness less than 2.5. A streak plate, which is commonly used for hardness tests, has a hardness of 6.5. Diamonds, the hardest minerals, define the 10 on the hardness scale. Using these common objects and their related hardnesses, one can easily identify the rock in question.
What type of mineral property is tested by the scratch test?
The scratch test measures a mineral's hardness, which is its resistance to being scratched. This property is identified by comparing the hardness of a mineral to the hardness of known minerals on the Mohs scale.
What classifies a mineral?
A mineral is classified as a naturally occurring inorganic solid with a specific chemical composition and a crystalline structure. Minerals often form through geological processes and can be identified based on their physical properties such as color, hardness, and cleavage.
Does the Mohs scale help scientists identify the crystal shape of a mineral?
The Mohs scale is a measure of hardness, not crystal shape. Crystal shape is determined by the internal arrangement of atoms in a mineral and is usually identified using X-ray crystallography or microscopy techniques.
Which legendary stone is said to be of impenetrable hardness?
The legendary stone that is said to be of impenetrable hardness is the Philosopher's Stone. It is believed to have the power to transmute base metals into gold and grant eternal life.
What is the definition of adamant?
A stone imagined by some to be of impenetrable hardness; a name given to the diamond and other substances of extreme hardness; but in modern mineralogy it has no technical signification. It is now a rhetorical or poetical name for the embodiment of impenetrable hardness., Lodestone; magnet.
Are minerals identified by their physical properties?
hardness,
What is hardness sometimes referred to as scratch-ability?
Hardness is sometimes referred to as scratch-ability because it measures a material's resistance to scratches or abrasions. Materials with higher hardness are less likely to get scratched easily compared to materials with lower hardness.
How do you get rid of water hardness?
Salt is sometimes used to remove water hardness. Borax and soda are generally used as well to remove water hardness.

How are the characteristics of a mineral identified?
Through testing of a sample to determine hardness, luster, streak, density, and chemical composition.
What is a hardness tree sap in which preserved insects can sometimes be found?
amber
How is a calcite or feldspar inditified?
Calcite can be identified by its rhombohedral cleavage and effervescence in acid. Feldspar can be identified by its two cleavage planes at nearly 90 degrees, and it often has a white to pink color. Both minerals can also be identified by their hardness using the Mohs scale.
What type of mineral property is tested by the scratch test?
The scratch test measures a mineral's hardness, which is its resistance to being scratched. This property is identified by comparing the hardness of a mineral to the hardness of known minerals on the Mohs scale.
How can a transparent stone be identified?
A transparent stone can be made of any material. If you suspect that it is a diamond, the field test for diamond is extreme hardness.
How much inches high is obsidian?
Obsidian is not identified, classified, or described by height. It is described by its texture, fracture, hardness, and chemical composition.
