So I picked up a stone that includes a quartz vein I guess (lots of quartz around where I live).

I wanted to try to dissolve limestone around it, see if it would reveal more quartz.

I went on weekend, when I came back, crystals formed on the evaporated surface. so I let to see and this grows.

any idea what this is ? limestone crystals ? some acid ? I know nothing in chemistry.

and by the same way if someone knows if my idea would work ?
