I have to learn a huge load of chemistry these days, which includes learning about the structure and reactions of salt. The daily table-salt 'NaCl' is one that appears rather often in my life, as it also does in the books. I know by now, how the atoms/ions connect to each other, that they form a specific, regular cristall-structure and how they dissolve in a polar solvent like water. I like learning this stuff. Signe Emma's images even give it an aesthetic value, a beautiful touch.
Thank you for that.
(you should really check her site, as the story to these images gives them another dimension more. and she has other funky stuff to offer too!)
