A few weeks ago I put some pure Sodium Chloride in a beaker with de-ionised water to dissolve, then pured in to a small glass bowl and lkeft it to evaporate.
All the water has now gone, so I examined the resulting crystals under my USB Microscope.
I think they turned out OK, well some did.

@zleap You can see the cubic crystals, nice
I can try with other stuff e.g Copper Sulfate. Salt is nice as it is safe, so kids can repeat the experiment.

Cool, is that as is, or did you need to dissolve then evaporate ?
@zleap as is
