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
Why can't the streak test be used to identify all minerals?
The streak test can only identify minerals that have a consistent powder color when scratched on a rough surface. It may not work well for minerals harder than the streak plate or those with a variable powder color due to impurities. Additionally, some minerals lack a distinguishable streak color, making it unreliable for their identification.
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.
Does gabbro have a streak?
Gabbro does not have a streak because it is a coarse-grained rock made up of minerals like plagioclase feldspar and pyroxene that are harder than the streak plate. As a result, gabbro does not leave a streak when rubbed on a streak plate.
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.
Why don't all minerals leave a streak?
Not all minerals leave a streak because streak is determined by the mineral's composition and hardness. A streak is produced when a mineral is scratched across a porcelain plate, and only those minerals that are softer than the plate can leave a mark. Additionally, some minerals may not leave a streak due to their crystalline structure or the nature of their surface, which can affect how they interact with the porcelain. Thus, only certain minerals, typically those with a hardness of less than 7 on the Mohs scale, will produce a visible streak.
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 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.
Streak of a diamond?
The streak of a diamond is transparent.First of all, diamond is spelled 'diamond'. Next, diamond might seem like it has a streak when it scratches something but that is only a scratch. Diamonds do not have a streak.
Which group of minerals is streak most useful for?
The colour of the streak left by a mineral is one of the features used to identify it. For instance, haematite leaves a red streak, malachite leaves a light green streak, while quartz, calcite and gypsum all leave a white streak.
