Want this question answered?
Minerals are tested for hardness by performing a scratch test. The unknown mineral is scratched with another object that the hardness is known. For example, a unknown mineral may be scratched with a piece of metal to compare the resistance.
Hello, It depends on what hardness do you want to test? The hardness of gems, one would use a scratch test. The Vickers hardness test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter can be used for all materials irrespective of hardness. The basic principle, as with all common measures of hardness, is to observe the questioned material's ability to resist plastic deformation from a standard source. The Vickers test can be used for all metals and has one of the widest scales among hardness tests. These are just examples of hardness tests, there are many! You should find out what you want to test for and find the most suitable test. Hope I Helped

The hardness scale
Yes "feldspar" is one of the minerals on Moh's scale of hardness.
Hardness of ductile materials can be determined by following methods..... 1) Brinell Hardness Test 2)Vickers Hardness Test 3)Rockwell Hardness Test 4) Scratch hardness test
In Vickers hardness test the for used is much lighter than the force used in Rockwell hardness test, The Rockwell hardness test is the considered to be the most routinely used technique to measure the hardness of materials because of its simplicity and because it does not require specific skills in order to perform it.

You can test its hardness on other minerals to find it hardness. It can help classify it better.
The Brinell hardness test is a standardized test in material science. It measures the hardness of a metal by measuring the indentation on the material caused by an indenter.
The initial load in Rockwell hardness test is 10KGf.
The Moh's scale is used to test the hardness of a mineral. It will be tested by a fingernail scratching it.
plan a fair test with timing......... bash each rock with a hammer and see which one breaks first
There are some differences between hardness and hardenability. Hardness is the surface property of material to give resistance to the penetration or plastic deformation and it is measured by one of the tests......Rockwell hardness test,Brinell hardness test and Vicker hardness test. On the other hand,hardenability is defined as the ability how the material would be hardened and it is measured by Jominy hardenability test.
