How can you use Quartz to determine the hardness of other minerals?
By using a simple scratch test, you can determine the relative hardness of an unknown mineral. Select a fresh, clean surface on the specimen to be tested. Hold the specimen firmly and attempt to scratch it with the point of an object of known hardness. In this example, we use a sharp quartz (H=7) crystal .
What would you expect to happen if you rubbed a mineral of hardness 7.5 against a piece of quartz?
What would you expect to happen if you rubbed a mineral of hardness 7.5 against a piece of quartz? The mineral would scratch the quartz.
How can you determine the hardness of a mineral?
It is a property by which minerals may be described relative to a standard scale of 10 minerals known as the Mohs scale of hardness. The degree of hardness is determined by observing the comparative ease or difficulty with which one mineral is scratched by another or by a steel tool.
How the property of hardness can be used to help identify minerals?
The ability to resist being scratched—or hardness—is one of the most useful properties for identifying minerals. Hardness is determined by the ability of one mineral to scratch another. Each higher-numbered (harder) mineral will scratch any mineral with a lower number (softer).
Which properties are used to identify minerals?
The physical properties of minerals are determined by the atomic structure and crystal chemistry of the minerals. The most common physical properties are crystal form, color, hardness, cleavage, and specific gravity. One of the best ways to identify a mineral is by examining its crystal form (external shape).
