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
@freemo
I can try with other stuff e.g Copper Sulfate. Salt is nice as it is safe, so kids can repeat the experiment.
@zleap @freemo What does regular salt look like, in comparison?
