You can perform a streak test which you test the true color of the mineral, you can test the smell by smelling it, you can test the hardness by trying to see what scratches what, test if it is magnetic, put vinegar on it and test the reaction to acid and much more.
In order to identify unknown minerals you can do many tests such as the following. A streak test can be performed. This is when you scratch the mineral along a streak plate and identify its streak. A hardness test can be performed. You can use the Mohs scale for reference. Scratch the mineral against your finger nail and on a penny ( You can used other things but these are the ones we used in class).If the mineral scratches both then the hardness is higher than 4. A cleavage and fracture test can also be performed. You can carefully look at the breakage of the mineral to see whether or not it is cleavage or fracture. If the mineral has smooth breakage around it has cleavage. If it has rough edges then it has fracture. Many other tests can be formed as well.
There are multiple ways to identify minerals. One way is by looking at the color. You could also use the luster of a mineral. Other ways are to look at the streak, hardness, smell, breakage, and feel. Two special ways to test and identify minerals is by seeing if they are magnetic and if they have a reaction to acid (fizzing).
We can perform the streak test and fernando that's not true. The streak test doesn't show the true color of the mineral it shows what color it produces in powdery form. We can do the acidic test when we put vinegar on the rock and see if it fizzes. You can test the hardness with the Mohs scale created by Friedrich Mohs. You scratch the mineral with an item with a certain harness. If that item scratches the mineral and the mineral scratches it than thats the minerals hardness. Like Talc is 1 and diamond is two. A finger nail will scratch talc but only a diamond can scratch diamond. You can find the luster,color and smell. But one other important one is magnetic. If the mineral is magnetic is ts magnetite. Finally cleavage and fracture. If the rock looks rough and jagged it's fracture if it's smooth than it is cleavage. Now we use the chart to match physical properties and find the name.

Tests we can perform to identify unknown minerals are the streak test, hardness, luster, reaction to acid, the smell, if it has cleavage or fracture and if the mineral is magnetic.
To identify a mineral you use its caracteristics. The characteristics are its streak, luster, magnetism, reaction to acid, smell, color, and hardness and also if it has cleavage or fracture.
you can perform many tests like the hardness test, the streak test, you have to check if it has luster, and also you need to check if they have either cleavage or fracture. you also have to check its reaction to acid ( vinegar)
there are many tests to identify a mineral. there is a streak test which shows the color of the powdered mineral by rubing a mineral on a streak plate. theres a hardness test that tell you the hardness of a mineral from a scale from 1 to 10. to figure that out you have to try to scratch a mineral with the objects that scratch a mineral. the luster is another test. it shows how light reflects a mineral. the color is also important. the acid test shows if a mineral reacts or fizzes to an acid. cleavage and fracture is how a mineral can be peeled. clevage is in sheets. fracture is jagged. how a mineral smells another test. how a mineral feels is another way to identify a mineral.
there are many test that we can preform, some are, streak test, color, cleavage and fracture, acidic, and hardness, these are just a few, there are many more
to identify a mineral, you can first identify the color, then the strreak test, then the hardness, then the luster, then the smell, after that the breakage,then if it is magnetic and lastly if it reacts to acid
To identify minerals, we can perform tests like the streak test, hardness, reaction to acid, magnetic, the breakage(cleavage/fracture) and basics like the color and how it feels.
There are many ways to determine what type of mineral it is. First, you can look at it's color and cleavage. Another way is that you can do a streak test. You can also have other tests like a chemical reaction test or a magnetic attraction test.
To determine what type of mineral it is you can look at its color... determine if it has fracture or cleavage. You can perform the streak test, you can test its chemical reaction and magnetic attraction.

You can test the reaction of minerals to acid, the streal test, the hardness, the luster, the smell, and if it has cleavage or fracture.
ReplyDeleteTests we can perform to identify unknown minerals are the streak test, hardness, luster, reaction to acid, the smell, if it has cleavage or fracture and if the mineral is magnetic.
