While a precise mineralogy of a rock can be determined via optical petrography or X-ray Defractometry (XRD). two simple test that you can perform in a classroom lab are acid tests and scratch tests.
Different minerals will dissolve in different acids. before the advent of spectrometry, many geologist would painstakingly dissolve rocks one mineral at a time to estimate their relative abundances. Dilute hydrochloric acid, or sometimes even vinegar, can cause certain carbonate baring rocks to bubble or fizz. This would imply the presence of Calcite, a calcium carbonate mineral, found commonly in schools in the form of chalk
Different minerals will also have different hardnesses. while this is rarely completely diagonal, this difference does help to narrow down possible minerals in a rock. if you can scratch a rock with just your fingernail, it is much softer than a rock that can scratch metal or glass. rocks hardnesses are classified on the Mohs scale from 1 to 10, 1 being the softest, might be talc (the source of talcum powder) while a 10, the hardest, might be a diamond. The are numerous kits available, including sample minerals and scratch plates, in order to test and compare a minerals hardness.
For example, if you found a white clear crystal, it might be difficult to tell just by looking at it if it were calcite or quartz. However if you could scratch it with something made of steel, like a nail. you would know that it has to have a hardness of less than 4. quartz has a hardness of 7, while calcite has a hardness of 3. If you had to pick between the two, calcite is probably the answer, and you could further test it by seeing if a drop of dilute acid makes it bubble.

A part that a rock is made of?
A rock is made of minerals, which are naturally occurring inorganic substances with a specific chemical composition and crystalline structure. These minerals are the building blocks of rocks and determine their color, texture, and hardness.
What do the minerals that a rock is made of determine?
The minerals in a rock determine its physical properties such as hardness, color, and texture. They also influence the rock's chemical composition and how it forms. Different minerals give rocks their unique characteristics and can help geologists identify and classify them.
How are rocks related to minerals?
Rocks are made up of minerals, which are naturally occurring inorganic substances with a specific chemical composition and crystalline structure. Minerals are the building blocks of rocks and determine their physical and chemical properties. Rocks can contain one type of mineral (such as limestone) or a variety of different minerals (such as granite).
Can minerals and common objects with the same hardness scratch each other?
No, minerals and common objects with the same hardness are not able to scratch each other and leave a mark behind. For example, minerals with a hardness of 2.5 - 3 include gold and silver. Try scratching two pieces of jewellery made of gold and silver. It does not make a mark at all!
Are all rocks made of minerals?
Not all rocks are made of minerals. Rocks can be composed of minerals or can be made up of organic materials like shells, fossils, or volcanic glass. Some rocks, like coal or obsidian, do not contain minerals but are still considered rocks.

It aids in the identification process, based on chemistry.

How do scientific tests help determine the properties of substance?
Scientific tests can help determine substances that appear similar but react differently under the same circumstances. By observing the reactions of the substance using an experiment, you can determine what that substance is made from.

Do minerals have to be man made?
Minerals can not be man made. If it is than its not a mineral.
Is the golf club made out of minerals?
Yes they are made out of tons of minerals!
Is igneous rock made out of minerals?
No it is not. Sedimentary rocks are made of minerals.
What made rocks?
Rocks which are made of minerals can be made up of many minerals and they can also be made up of only one mineral. Generally rocks are made of two or more minerals
