The hardness of a steel nail is about 4.5 (About the same hardness of the mineral Fluorite.)

∙ 13y agoYou would attempt to scratch a crystal face of a mineral with a known Mohs hardness with the point of the nail. For instance, if the nail would scratch feldspar (Mohs 6), but not scratch quartz (Mohs 7), then the hardness of the nail would be between 6-7 on the Mohs hardness scale.

HOW HARD WOULD AN ALUMINUM NAIL BE AND WHERE WOULD IT GO ON MOHS SCALE?
Pretty soft. Hardness is around 2.5 to 3, depending on the aluminum alloy.
How is mineral hardness tested?
Mineral hardness is tested on a glass plate or usually a finger nail.
What is the diffrent between a magnetised steel nail and an unmagnetised steel nail?
what is the diffrence between a magnetised nail and a unmagnetised nail
Name the basic parts of the nail unit?
The basic parts of the nail unit include the nail root,nail bed,nail plate,cuticle,perionychium and the hyponychium.The nail plate,the nail bed,the cuticle,the matrix,the nail folds and the lunula are the basic parts of the nail unit.
Is the ester in nail varnish remover a solution?
The ester in a nail varnish is a good solvent that is used in nail polish removers because it dissolves the nail varnish and does not affect the nail.
How hard is a finger nail on the mohs hardness scale?
It is about 2.5 in the Mohs Hardness Scale.
Can fluorite be scratched by a steel nail?
Yes. A steel nail has a Mohs hardness greater than that of fluorite.
How can you find hardness of a mineral?
Try scratching it with a variety of other objects (fingernail, steel nail, glass) whose hardness is known. Refer to the Mohs Hardness scale for more info on the hardness of specific materials
What minerals have a hardness of 7 on the mohs scale?
Topaz is a common mineral with a hardness of 8 on the Moh's hardness scale. This means it can scratch glass and cannot be scratched with a knife blade or masonry (steel) nail.
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 HARD WOULD AN ALUMINUM NAIL BE AND WHERE WOULD IT GO ON MOHS SCALE?
Pretty soft. Hardness is around 2.5 to 3, depending on the aluminum alloy.
Resistance of a mineral to abrasion is known as?
The resistance of a mineral to being scratched is known as its 'hardness'. This is a relative measurement determined by whether it scratches, or is scratched by, other materials of determined hardness. Hardness is measured on the Mohs scale. To give to some idea, diamond (the hardest known mineral) is a 10, while talc (the softest) is 1. A copper coin is around 3, a fingernail is around 2, an iron nail is around 5. Quartz, for example, is a 7.
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.
What can talc scratch?
Talc can scratch Talc , although Talc's hardness varies it is considered a soft mineral, that can even be scratched with a finger nail. Any mineral or material with a hardness equal to or greater than 1 on the Mohs hardness scale will be able to scratch talc. Talc is the softest mineral listed on the Mohs scale, listed as a 1 on the scale which is graded from 1 through 10, with 10 being the hardest (diamond).
What is the hardness of a mineral that scratches gypsum?
On the Mineral Scale: 2 General Hardness: Softer than the human finger nail
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.
What hardness does a mineral have if it does not scratch glass but it scratches an iron nail?
The hardness would be between 4.5 and 5.5 on the Mohs scale. I actually think it would be 4.5, but to be safe, I would put between 4.5 and 5.5. Hope that helps!
