Yes because they bite you. It sometimes leaves a mark or something.
When a mineral scratches a porcelain tile, it leaves a mark that can appear as a streak or a line on the surface of the tile. This mark is typically indicative of the mineral's hardness, which can be assessed using the Mohs hardness scale. The scratch may vary in depth and visibility depending on the hardness of the mineral compared to the porcelain. Porcelain tiles are generally quite hard, so only harder minerals will leave a noticeable scratch.
I can help you! So first determine whether the mineral is light or dark. If it is light' you can use a chalkboard slate or even another darker mineral. You rub the mineral on the other solid and see if it leaves a mark If it is dark you simply do the same rubbing but use a light mineral. :)
Graphite leaves a streak on paper, as it is the material commonly found in pencils. The black mark left on paper is due to the graphite particles rubbing off onto the surface.
