The test is called a streak test and it leaves a powdered form of the mineral on the porcelain. The powdered mineral reveals the true color, of the mineral specimen, which may or may not match the color of the specimen.
By rubbing mineral against a piece of porcelain tile, the objective of the test is to observe the hardness of the mineral.
Geologists use properties such as color, luster, hardness, cleavage, and specific gravity to identify minerals. These characteristics help in distinguishing one mineral from another based on their physical and chemical properties.
Physical properties used to help identify minerals. Luster refers to the way a mineral's surface reflects light, while color is its appearance. Streak is the color of a mineral's powder when scratched against a rough surface. Cleavage is how a mineral breaks along flat planes, hardness is its resistance to scratching, and density is its mass per unit volume.
yes it is
quartz will have conchidal fracture...plagioclase will have 2 sets of cleavage near 90 degrees and some striations quartz will have conchidal fracture...plagioclase will have 2 sets of cleavage near 90 degrees and some striations

Color, streak color, hardness, cleavage, and chemical.
Hardness, Cleavage, Luster, Color, Streak, and Texture.
The test described is called a streak test, and indicates the true color of a mineral as observed in a powdered form.
You can use the characteristics(color, luster, streak, hardness, cleavage, fracture, and crystal).
By the mineral color, streak color, luster, hardness, the property of the mineral, if it's fracture or cleavage and it's specific gravity. Those are just basic, so there's many other ways to ID a mineral.
The seven characteristics used to identify minerals are color, streak, luster, hardness, cleavage, fracture, and specific gravity. These properties can help differentiate one mineral from another based on their unique physical and chemical properties.
Minerals have certain properties, or characteristics, that help to identify them. Minerals can be identified by their color, luster, streak, cleavage, hardness, specific gravity, and even by their chemical composition.
Observable properties are: color and streak, luster, cleavage and fracture (crystalline structure), and hardness.
In a hand sample/specimen you can the properties used to identify minerals are luster, diaphaneity, color, streak, luminescence, play of colors, crystal shape, tenacity, cleavage, hardness, specific gravity and density, magnetism, electrical properties, reaction to acid.
