No it does not work with all minerals. For if you did not know streak plates have a hardness of 7 (maybe a little lower or higher) on the Mohs scale. Some minerals are harder than 7 though. If they are harder they will not work with the streak test. some examples are Diamond, topaz, and corundum.

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.
What four characteristics do all minerals share?
property,cleavage,fracture,streak
What is facture of a mineral mean?
'Fracture' means 'to break'. Minerals often break (or fracture) in certain directions that many other minerals do not. The way a mineral fractures, then, helps a person narrow down the identity of the mineral. Fracture, along with color, streak color, hardness, and specific gravity are all used in the identification of minerals.
Can a minerals be gemstones?
No not all. Some minerals are metals.
What are Diamondsrubiesopals emerald and sapphires are all examples of well they are all minerals but also gemstones?
yes they are all minerals and gemstones
What test is used to identify a minerals color?
A streak test is used to determine a minerals streak color. This can help in with the identification of minerals. A streak test is performed by rubbing the mineral on an unglazed ceraminc tile, then observing the color of the streak which is left behind. All minerals do not leave streaks. Harder minerals will not streak, but this can also be used as a tool for identifying the mineral, if you are familiar with the hardness scale.
Why can't the streak test be used to identify all minerals?
Because some minerals dont have a streak, or may share a streak colour with another mineral.
Does gabbro have a streak?
Only minerals have a streak, not rocks. The constituent minerals of a gabbro will all have a streak.
Can all minerals produce a streak on a porcelain plate?
Those minerals that are harder than the unglazed porcelain streak plate will scratch it rather than leave a streak.
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.
Do all mineral leave a streak?
Shale is a type of rock, not a mineral. Streak is used to help classify minerals. It can leave a streak, but it doesn't mean anything.

What are all the characteristics of all minerals?
The charactristics of a mineral is, streak, luster, density, hardness, crystal system, cleavage and fracture, and special properties.
Luster color streak cleavage hardness and denisty are all?
Properties used to identify minerals.
What is the substances that minerals leave a brown mark on?
You may be thinking of unglazed porcelain, used in streak tests? The reason I'm not sure is that different minerals leave different color streaks. After all, it's not much of a test if there's never any difference in the results: "Let's try the gravity test... yep, falls down; you know, I'm starting to think that maybe this test is a waste of time."
