What minerals can a steel nail not scratch?
A steel nail cannot scratch minerals that are harder than itself, which has a Mohs hardness of about 4.5. This means it cannot scratch minerals such as quartz (hardness 7), topaz (hardness 8), corundum (hardness 9), and diamond (hardness 10). These minerals possess greater hardness and will resist scratching by a steel nail.

Why is streak and hardness poor tests used to identify gold?
Streak and hardness tests are considered poor for identifying gold because gold has a distinctive yellow color that does not change when scratched (streak test) or when subjected to hardness testing. Gold is also a relatively soft metal with a hardness of around 2.5-3 on the Mohs scale, meaning it can be easily scratched by many common objects, making hardness testing less reliable for gold identification.
Is gold harder than pyrite?
