What other minerals can scratch Talc?
All of them
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.
Is a hammer and a nail a mineral?
are there minerals in hammers and nails
What mineral can scratch glass but not steel file?
n
What mineral can't scratch quartz?
Anything under the 7 of the Moh's Hardness Scale, which is the number assigned to quartz. Minerals that can scratch quartz include topaz, corundum and diamond - pretty much everything else won't scratch it.
What minerals can a steel knife scratch?

Can magnetite scratch other rocks and minerals?

Can magnetite can scratch other rocks and minerals?

What is the hardness of a steel nail on the Mohs scale?
The hardness of a steel nail is about 4.5 (About the same hardness of the mineral Fluorite.)
What minerals are in hammer and nail?
Steel is used to form both hammer and nails.
What do you mean by hard substances?
Hard substances are those which are difficult to scratch. For instance candle wax is not hard, you can scratch it with your finger nail. This means your nail is harder than wax. However, an iron nail could scratch your finger nail, but not the other way round, so an iron nail is quite hard. Diamond is the hardest natural substance.
How can one determine the hardness of a mineral using Mohs scale need explain the technique and what is Mohs scale?
The Mohs Scale of Hardness is used to measure hardness of a mineral, which is its resistance to scratching. It is a quantitative scale, which relies on the relative hardness of other minerals . Higher numbered minerals scratch lower numbered ones. You can use every day objects like a glass plate, a knife, or a nail to distinguish hard and soft. Hard minerals scratch glass, but can't be scratched with a knife blade of a nail. Soft minerals will not scratch glass, but can be scratched with a knife blade or masonry nail. You can purchase hardness kits to help make these distinctions.
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.
Can a diamond scratch a nail?
Yes: not a good use for a diamond, but yes, a diamond will scratch a nail.
Can steel scratch a diamond?
No. Diamond will scratch steel, however,
Can opal be scratched by a nail?
It depends. Opals range between 5.5 and 6.5 on the Mohs hardness scale (how easy it is to scratch) which is kind of soft, so when used in jewelry they are usually coated with a polymer that provides a thin layer of protection against every day wear and tear. Now, when you say "nail" do you mean finger nail (hardness 2.2-2.5, NO) or a metal nail you hammer? And if a metal nail, made of what metal? See, iron, nickel, and carbon steel are only around a hardness of 4-5 (won't scratch an opal), but some nails are made out of hardened steel which at 7.5-8 WILL scratch an uncoated opal.
Which minerals cannot scratch any minerals by itself?
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.
