Scratch is a free programming language and online community where you can create your own interactive stories, games, and animations.Observe Scratch Patterns: Examine the scratch patterns left by the minerals to identify any visible differences in hardness. Repeat Tests: Perform multiple tests using different hardness picks to verify and confirm the mineral's hardness level. If you're unsure of the results, try scratching the minerals in different directions. The actual scratch test is performed by applying a constant force or progressively increasing the force on the indenter as it moves across the sample surface at a constant speed. This process is conducted until failure events happen, such as scratch tracks, which can be further analyzed to determine the material’s resistance to wear and .

Mohs hardness kit, containing one specimen of each mineral on the ten-point hardness scale. The Mohs scale (/ m oʊ z / MOHZ) of mineral hardness is a qualitative ordinal scale, from 1 to 10, characterizing scratch resistance of minerals through the ability of harder material to scratch softer material.. The scale was introduced in 1812 by the German geologist and mineralogist .
The first introduction of the scratch test as a qualitative method of measuring coating adhesion was in the 1950s by Heavens [1] who applied a constant load to the sample surface via an indenter in order to damage the surface by scratching and induce delamination of the film.The applied loads that created specific damage, especially cracks or delamination, . Xu and Yao [38] proposed that the scratch tests with low loading levels can be applied to characterize the main phases in cement paste.
