limestone's hardness is 3-4 and it does not have a luster it's main constituent is the mineral calcite, and has a vitreous or glass luster.
Nope. It is actually the hardness. I'v been trying to find out what the Luster scale is myself....:S
A diamond is the hardest natural substance, scoring a 10 on the Mohs scale. It has a brilliant luster due to its high refractive index. The streak color of a diamond is colorless, as it does not leave a streak on a streak plate.
Yes, anhydrite is generally harder than limestone. Anhydrite, which is composed primarily of calcium sulfate, typically has a hardness of around 3 to 3.5 on the Mohs scale, while limestone, primarily composed of calcium carbonate, has a hardness of about 3 to 4. However, the hardness can vary depending on the specific type of limestone and its mineral content. Overall, anhydrite is considered to be more resistant to abrasion compared to limestone.
Petroleum is a liquid mixture of hydrocarbons. It does not have a streak luster, hardness, or crystal system as it is not a mineral but rather a naturally occurring substance derived from organic matter.
Limestone is a relatively soft sedimentary rock composed mainly of calcium carbonate. It has a hardness of 3 on the Mohs scale, which means it can be easily scratched by harder materials like metal or glass.
Yes, limestone typically has a dull or earthy luster due to its high calcium carbonate content and fine-grained texture. It does not usually exhibit a shiny or reflective appearance like some other minerals or rocks.
Anything higher on the hardness scale for example if limestone has a hardness of 4 then it would take something with a hardness of 4 or higher to scratch it.

The hardness is 3-4 on Mohs scale.
Plutonium is a silvery metal.- Vickers hardness: 255 - Brinell hardness: 242 - Mohs hardness: cca. 3,7
The four properties of minerals are color, streak, hardness, and luster. Color refers to the outward appearance, streak is the color of a mineral when it's powdered, hardness is the resistance to scratching, and luster describes the way light reflects off the surface of a mineral.
"Tuff", a rock made up of volcanic ash and other things, is not a mineral, so it has no hardness index or luster.
