The Mohs hardness scale is a commonly used hardness scale for minerals. It is on a scale from 1 to 10 (1 being the softest and 10 being the hardest). You can purchase Mohs hardness kits which has a variety of minerals with known hardnesses that you can test your rock against. What you will do is try and scratch your rock with the minerals in the kit. If the mineral in the kit removes material from your rock then your rock is softer. Continue up or down the scale until you find where your rock lies, probably in between two rocks. It will be difficult to measure if your rock is something like sandstone or has an inconsistent composition because certain parts of the rock will be harder than others and sandstone has a very loose bond.
Talc (1 on the scale) is one of the softest minerals and diamond is the hardest (10 on the scale). Onyx is also very hard (9 on the scale). If you don't have a scale then you can use your fingernail which is approximately 2.5, a penny is approximately a 3.5, glass is a 5.5, and a knife is a 7.

What is the hardness of serpentine rock?
Serpentine rock has a wide range of hardness depending on its composition, but it typically falls between 2.5 and 4 on the Mohs hardness scale.
How do you find out what kind a rock is?
To identify a rock, one can start by observing its color, texture, and mineral composition. Tools such as a hand lens or a geologist's hammer may be used to examine the rock's features more closely. Additionally, conducting tests like a scratch test or a streak test can help in determining the rock's hardness and characteristics.
What is the hardness of rhyolite?
depends a rock made from lava is an igneous rock.
What is the hardness of andesite rock?
Andesite rock typically has a hardness of around 7 on the Mohs scale, which means it is relatively hard and durable. It is commonly used in construction and landscaping due to its strength and resistance to wear and erosion.
What is Oklahoma rose rock on the hardness scale?
Oklahoma rose rock has a hardness of around 2.5-3 on the Mohs scale of mineral hardness. This means that it is relatively soft compared to other minerals and can be easily scratched by harder materials.
What is the hardness of andesite?
Andesite is classified as an extrusive rock and the name of this rock is South American in origin. However, the hardness of this rock is not listed.
What does rubbing a rock against porcelain do?
Rubbing a rock against porcelain can test the hardness of the rock. If the rock leaves a scratch on the porcelain, it indicates that the rock has a higher hardness level than the porcelain. This can help in identifying the relative hardness of the rock based on the Mohs scale.
What is the hardness of serpentine rock?
Serpentine rock has a wide range of hardness depending on its composition, but it typically falls between 2.5 and 4 on the Mohs hardness scale.
If rock A cuts across rock B what does this indicate about their hardness?
If rock A cuts across rock B, it indicates that rock A is harder than rock B. Harder rocks are able to cut across softer rocks, indicating the relative hardness of the two rock types.
How do you test the property of HARDNESS?
Actually yes, testing a hardness of a rock can be done at another rock to see if it is harder than another rock. You scratch another rock to measure, or you can use a thing designed like a pen with a number (moh's hardness scale) of the rock for it.
Classification of a rock determined by making a scratch on it?
The scratch test is used to determine a rock's hardness on the Mohs scale, which ranges from 1 (softest) to 10 (hardest). By scratching a rock with a known mineral or material of a specific hardness, you can compare the scratch to known hardness values to classify the rock. This test helps in identifying the rock's mineral composition and potential uses based on its hardness.
