What type of mineral property is tested by the scratch test?
the anwers is hardness because a have a sience book that it says the same thing
What mineral test leaves a line of powder on a plate?
It is called the streak test. It can help identify the mineral by the color of the streak that is left.
How is the hardness range for a mineral determined?
The answer is quite complicated in fact I don't know the exact answer. What I really know is that a geologist will probably know the exact answer. Geologists study rocks and rocks have lots of minerals. You can search the answer as well by looking at geologist websites. If it doesn't work then I hope someone else can edit this answer.
Rubbing a mineral against a piece of unglazed ceramic tile is a test for .?
Rubbing the mineral against an unglazed ceramic tile, called a streak plate, leaves a streak of the powdered mineral. This powder reflects the true color of the mineral. It's called a streak test, and the resultant line of color is called the streak. A link can be found below to check facts and learn more.
What is the difference between streak and hardness?
A minerals hardness is its relative ability to scratch or be scratched by other minerals. Diamond, for instance, can scratch all other minerals because of its hardness. Streak is the color of the mineral when powdered. This is usually accomplished by the streak test (swiping the mineral across an unglazed porcelain surface) which reveals a mineral's streak color, which may differ from the color of the specimen being tested.
What mineral is used to perform a scratch test?
Bold
What is the difference between a scratch test and a streak test?
a streak test is a test wheree you rub a mineral across a streak plate to see the color of its streak, which is a better indentifying factor of the mineral than the external color. A scratch test is when you scratch a mineral to find out its hardness on the Mohs Scale of Hardness. This is also another useful identifying factor
What is the purpose of a scratch test?
The scratch test is used for identifying minerals.You simply get a hard, white surface, and scratch the mineral on it.
What type of mineral property is tested by the scratch test?
the anwers is hardness because a have a sience book that it says the same thing
What is a way to identify minerals?
The scratch test, use a series of mineral with known hardness and scratch the mineral. From softest to hardest, and note where a scratch is made. You can also look for distinctive physical characteristics.
How do you estimate the hardness of a mineral that i'snt on the mohs scale?
By undergoing scratch test.
How is mineral hardness tested?
Mineral hardness is tested on a glass plate or usually a finger nail.
What kind of test is it when you scratch a mineral with a nail?
Most likely you would be testing to see if the mineral was harder or softer than the nail.
What is a mineral scratch test?
In 1822 scientist Friedrich Mohs developed a scale to measure the hardness of minerals. A mineral will scratch other minerals softer than itself and will be scratched by minerals that are harder.
Which mineral identification test is easiest for a person to perform at home?
streak is a real simple test, as is visual appearance.
What test would you perform to distinguish hematite form copper how would you carry out this test?
A few things used to identify minerals are streak tests, hardness, cleavage, solubility, magnetic.Streak test: When you scrape a mineral on a streak plate it leaves behind powder of a certain color. Hematite leaves a red streak. I don't know what streak copper has.Hardness test: minerals have different hardness, their ability to be scratched or scratch. this can be determined by seeing if you can scratch a mineral with your finger nail or if the mineral will scratch a piece of glass. I don't know if this test will do much good though in determining copper from hematite.Cleavage: Cleavage in mineralogy refers to when you break a mineral, how it fractures. Does it fracture into cubes, rhombus shapes, conchoidal, etc.Solubility: copper is soluble in acids and forms green-blueish solutions, hematite is insoluble.Magnetic: hematite is sometimes slightly or strongly magnetic. copper is not magneticAfter you test your samples, look up in a book or manual to see which mineral(s) have matching properties.
What you find when scratch a mineral over an unglazed tile?
What you are referring to is called a streak test. It's used as an aid to mineral identification. As a mineral is drawn over the unglazed tile surface, it is reduced to a streak of dust which reveals the true color of the mineral. If no color is revealed, the streak color is called white. An amethyst crystal which appears purplish will actually have a white streak, because the streak color of the constituent quartz is white. The purplish color of amethyst is due to other reasons.
