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.
Limestone typically has a hardness of about 3 to 4 on the Mohs scale, which translates to approximately 1,500 to 4,000 psi (pounds per square inch) in compressive strength. However, the exact hardness can vary based on the specific type and composition of the limestone. Generally, limestone is relatively soft compared to other rocks, making it easy to work with in construction and sculpture.
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.
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.

Plutonium is a silvery metal.- Vickers hardness: 255 - Brinell hardness: 242 - Mohs hardness: cca. 3,7
The hardness is 3-4 on Mohs scale.
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.
