fine salt 40X
When I took a look at the salts under the microscope, one immediate fact catches my eye: The molecules of sodium and chloride combine into a cube-like pattern, meaning it is shaped symmetrically unlike most compounds such as sugar.



fine salt 40X dark field

When dark field is used, it is significantly easier to view transparent compounds or organisms because it blocks out the central light entering. So here, I was able to see in detail the compounds binding the salt in place, which surprisingly didn't give off a cube shape like the previous picture.
