Talc is supposed to be too fragile to cause a scratch on the majority of minerals.
Talc and gypsum are two minerals that can be scratched with a fingernail due to their low hardness on the Mohs scale.
Talc is the mineral that cannot scratch any mineral by itself. It has a Mohs hardness of 1, making it the softest mineral on the Mohs scale, which means it can be easily scratched by all other minerals.
The most commonly known mineral that can be scratched with a fingernail is talc.
A steel knife can scratch minerals with a hardness lower than that of steel, such as gypsum, calcite, fluorite, and talc. Minerals like quartz, topaz, and corundum are harder than steel and cannot be easily scratched by a steel knife.
You can tell if a mineral can scratch another mineral by performing a scratch test, where you use the hardness scale to compare the minerals. If the mineral you are testing can scratch the other mineral, then it has a higher hardness on the scale.
All of them
Diamond is the hardest naturally occurring mineral and can scratch all other minerals. Talc is the softest of minerals and cannot scratch any other mineral.
Talc and gypsum are two minerals that can be scratched with a fingernail due to their low hardness on the Mohs scale.
The answer will depend on the mineral. Some minerals, such as talc, are extremely soft and will not mark the tile.
Talc can scratch gypsum, but can be scratched by all other minerals. Talc is the softest mineral on the Mohs scale, with a hardness of 1, making it easily scratched by minerals with higher hardness values. Gypsum has a Mohs hardness of 2, so talc can leave a mark on it.
Diamond can scratch talc but is not scratched by calcite. Diamond is the hardest mineral on the Mohs scale, making it capable of scratching minerals with a lower hardness, like talc.
The scratch table is called the Mohs Scale of Mineral Hardness and measures the hardness of minerals in relation to the known hardest (diamond) and softest (talc) minerals.
Fluorite has a hardness of 4 out of 10 and can scratch gypsum, talc and anything less than 4.
Talc is the mineral that cannot scratch any mineral by itself. It has a Mohs hardness of 1, making it the softest mineral on the Mohs scale, which means it can be easily scratched by all other minerals.
Yes. But only soft ones such as talc (solid form of chalk and baby powder). Generally only minerals below 2 on the hardness scale.
The most commonly known mineral that can be scratched with a fingernail is talc.
you can scratch talc becuase it is the softest mineral on the moth scale.
