Mineral Name

The brakes in number three minerals it’s a nice clean 90° and it’s a three-dimensional cubicle crystal structure. And put a drop of HCL acid onto the material 3 it forms bubble(react with it).
Mineral 18, little bit of shine it can mark on the ceramic, with a great colour
Mineral 17. Very obvious colour of yellow and not shiny and scratch it with the finger nails he can easily be scratch it. And it has a smell of eggy.
Mineral 23.It can see some shiny, and it has some sort of magnetic property, because it can be moved by the metal.
Mineral 12 first looking to the hardness. It can scratch the copper and glass. Make no damage to the ceramic. I’m actually. The cleavage, it’s not in the nice right angle.
