Hardness: Try to use it to scratch other minerals and have other minerals scratch it. Take for example quartz. It's a 7.0 and will scratch every mineral below a 7.0 on the Mohs hardness scale. However, it will be scratched by everything above it such as Diamond (10.0) and Corundum( rubies andsapphires, 9.0)
Streak: Use a streak plate and simply run the mineral down the plate
Density: Find the mass and volume of the mineral. For volume you'll more than likely, have a mineral that will beirregularlyshaped. You'll have to use the displacement method by filling a graduatedcylinderwith x amount of water and put the mineral inside subtracting and before and after water placement and find the difference. After this, you'll divide the mass by volume and you'll get your answer to the density of the mineral.
What else can I help you with?
What are 7 ways to determine the identity of a mineral?
Color: Observe the color of the mineral. Hardness: Use the Mohs scale to determine the mineral's hardness. Cleavage and fracture: Check how the mineral breaks. Luster: Determine if the mineral is metallic or non-metallic. Streak: Identify the color of the mineral's powdered form. Specific gravity: Measure the density of the mineral. Acid reaction: Test if the mineral reacts with acid.
How are the characteristics of a mineral identified?
Through testing of a sample to determine hardness, luster, streak, density, and chemical composition.
What properties does a mineral?
color, luster, fracture/cleavage, streak, hardness, density

How do you test a mineral for hardness?
Well. You can do many things like use the Mohs Hardness Scale or determine the hardness by the streak.
What are the four main tests used to identify a mineral?
streak, hardness, density, luster.
Would the hardness of a mineral affects its performance in the streak test why or why not?
No, the hardness of a mineral does not affect its performance in the streak test. The streak test measures the color of the powdered form of a mineral when it is scratched against a streak plate, regardless of the mineral's hardness.
How do you identify all the properties scientists use to classify minerals?
Scientists classify minerals based on properties such as color, streak, luster, cleavage, fracture, hardness, density, and crystal habit. By observing these properties, scientists can determine the identity of a mineral and place it into the appropriate mineral group.
True or false the streak test is a test of mineral density?
False. The streak test is not a test of mineral density but is used to determine the color of a mineral in powdered form by scratching it on a ceramic plate.
What is the hardness of a porcelain streak plate?
Porcelain has a Mohs hardness of approximately 6-7, making it a relatively hard material. This hardness allows porcelain to be used as a streak plate in mineral testing to determine the color of a mineral's powder when scratched against it.
How do you determine quartz sand from silica sand?
There are a few ways:1) colorand lustre2) The color of the mineral's streak on a streak plate3) The hardness of the mineral on the Mohs hardness scale (I knowquartzis a 7.0, but I'm not sure aboutsilicasand)
Would the hardness of a mineral affect its performance in the streak test Why or why not?
No. Streak color is distinct of mineral hardness. They are separate properties.
