If the sum of the digits of a number is divisible by 3, then the number is divisible by 3.
For example the M3 Half track was Model #3 in the series
The mineral with hardness 3 will get scratched.
I have the same question and the research that I am doing tells me that the best would be 3 in 1, and second mineral or baby oil. It seems that both work for what I am reading.

Wulfenite has a mineral hardness of 3-3.5 on the Mohs scale, which means it is relatively soft and can be easily scratched by harder materials.
To distinguish between a mineral with a hardness of 6 and one with a hardness of 4, you can use the glass plate and the copper penny for comparison. First, scratch the mineral against the glass plate; if it scratches the glass, it has a hardness greater than 5. Then, use the copper penny to scratch the mineral; if the mineral scratches the penny, it has a hardness greater than 3. If it scratches the glass but not the penny, it has a hardness of 6; if it scratches the penny but not the glass, it has a hardness of 4.
