Where does the hardness of the nail come from?
The hardness of the nail comes from a tough protein called keratin, which makes up the structure of the nail plate. Keratin provides strength and durability to the nail, allowing it to protect the sensitive tissues underneath and withstand everyday wear and tear.
What does the nail plate contain?
The nail plate is made up of a tough protein called keratin, which provides strength and protection to the nail. It also contains water, oils, and minerals that help maintain the nail's flexibility and hardness. Additionally, the nail plate is composed of overlapping layers that are continually produced by the nail matrix at the base of the nail.

hardness
Can fluorite be scratched by a steel nail?
Yes. A steel nail has a Mohs hardness greater than that of fluorite.
Can halite be scratched by a nail?
Halite has a hardness of 2.5 on the Mohs scale, while a fingernail has a hardness of about 2.5 as well. Therefore, halite can be scratched by a nail.

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.)
Scratching a mineral with a nail is a test of what?
Scratching a mineral with a nail is a test of hardness. It helps determine the relative hardness of the mineral compared to known substances on the Mohs scale of mineral hardness.
What hardness does a mineral have if it scratched by glass but scratched an iron nail?
It would have to be 5.0 because glass has a hardness of 5.5 and an iron nail has the hardness of 4.5

How is hardness tested?
Mineral hardness is tested on a glass plate or usually a finger nail.
Scratching a mineral with a nail is a test of?
Scratching a mineral with a nail is a test of hardness. The Mohs scale of mineral hardness ranks minerals from 1 (softest) to 10 (hardest), with talc being the softest and diamond being the hardest. If a mineral can be scratched by a nail (with a hardness of around 2.5), it would be classified as having a hardness lower than 2.5 on the Mohs scale.
