How do you identify minerals with your naked eyes?

by simply testing the streak of the mineral. all minerals have a different streak take a streak plate and scrape the rock down it in a straight line and the color should tell you what mineral it is :) that's the best way.


Who developed a way to classify minerals by their hardness?

The big two are the Rockwell and Mohs Scales.


What can you rub a mineral on to leave a clue what the mineral?

A streak plate, or unglazed white porcelain tile, is used to perform streak tests which can help to identify minerals. Rubbing the mineral on the streak plate will finely powder it and reveal the color of the powder, which in some cases is quite different from the color of the mineral. Eg: hematite is black but has a red streak - a good way to tell you have hematite instead of one of the many other shiny black minerals.


Why Is Streak A Useful Property For Identifying Minerals?

The streak of a mineral is much more accurate in identifying a mineral than color. The streak of a mineral can distinguish minerals with metallic and non-metallic luster. For example, metallic minerals generally have a dark streak whereas non-metallic luster minerals often have a light colored streak.


How do you identify minerals according to streak?

Minerals can be identified by their streak, which is the color of the mineral when it is broken down into a powder. To test a mineral's streak, a streak plate (usually made of unglazed porcelain) is used. The streak is usually compared to a streak color chart, which contains the colors of a variety of minerals. To test a mineral for its streak, take a small piece of the mineral and rub it on the streak plate. The resulting powder is then compared to the streak chart to identify the mineral. Streak is an important property of minerals because it is more reliable than the external color of the mineral. External color can be altered by impurities and oxidation, but the streak of a mineral does not change. Therefore, testing a mineral's streak is an effective way of identifying it.When identifying minerals according to streak, it is important to consider the following properties: Color - the color of the powder when rubbed on the streak plate. Luster - the shine of the powder when rubbed on the streak plate. Texture - the feel of the powder when rubbed on the streak plate. Opacity - the transparency of the powder when rubbed on the streak plate.By considering these properties when testing a mineral's streak, it is possible to identify the mineral accurately and quickly.


What are the four properties of minerals?

The four properties of minerals are color, streak, hardness, and luster. Color refers to the outward appearance, streak is the color of a mineral when it's powdered, hardness is the resistance to scratching, and luster describes the way light reflects off the surface of a mineral.


Can minerals in a rock can change the way they look?

Yes, because minerals have a certain texture, color and streak color. Minerals also have some luster in them. Therefore, they could change anything about the rock.


What do cleavage and streak have in common?

Cleavage and streak are both properties used to identify minerals. Cleavage refers to the way a mineral breaks along planes of weakness, while the streak is the color of the powdered form of a mineral when rubbed against a hard surface. Both characteristics are important in mineral identification and classification.


What is the difference between luster and streak?

Luster refers to the way light interacts with the surface of a mineral, giving it a specific sheen or shine. Streak, on the other hand, refers to the color of the powdered form of a mineral when it's rubbed against a rough white ceramic plate. Luster helps in identifying minerals based on their appearance, while streak helps distinguish minerals by their color.


What type of minerals are there?

There are several thousands of minerals, and many different ways to classify them. An easy way to separate them into two types is to call them either metallic or non-metallic.


One way to help identify a mineral is to rub it against a piece of porcelain tile This procedure tests the of the mineral?

That procedure tests the streak of the mineral. Oddly, the streak color of some minerals are different from the mineral's color.


How are mineral indentify?

Minerals can be identified by such as their color, streak, luster, and their hardness. What does streak, and luster mean?Streak-- Is the color of a mineral's powder for example: talc is a mineral and it is also powder and its streak is white.Luster-- Is the way a mineral reflects light from it's surface for example: glassy, pearly, silky, metallic and earthy can be words to describe luster.
