Chemical Clouds

A photo of the cauliflower-like structures sodium chloride (table salt) can form when left to evaporate through a porous substrate. The slight yellow colour is from traces of red prussiate (potassium hexacyanoferrate(III))

 

The final result was made through focus stacking of several separate photos.
