  1. CuSO4 & KCl πŸ”¬ πŸ’Ž βš—οΈ

    A pleasant succession of crystal shapes. The star-shaped ones can hardly be discerned at the end.

  2. RuCl3 & NaCl in evaporating H2O πŸ’Ž πŸ”¬ βš—οΈ

    Fairly small quantities of RuCl3 can produce pitch black aqueous solutions, from which we gradually see crystals of NaCl emerge here.

  3. Rhodium (iii) chloride is a deliquescent substance that forms red aqueous solutions. It is here combined with NaCl. One of the stable phases we may thus afford is Na3RhCl6.

  4. βš—οΈ cyanotype βš—οΈ chemistry βš—οΈ
    In cyanotype, we employ K4Fe(CN)6 and a light-sensitive source of Fe(III), to displace K+ and form insoluble prussian blue. Here instead I added an excess of FeCl3β€’7H2O as a moisture-sensitive source of Fe(III). Dark shades of green and blue indeed develop initially, but we then proceed to form something else.

  5. MnCl2β€’5H2O πŸ’Ž in HgCl2(aq). After two days of dissolution and growth due to humidity variations, we're now gradually seeing very neat crystal shapes that develop.

  6. πŸ’Žβš—οΈπŸ§ͺ🧫🌧️ Deliquescent HgCl2 picks up moisture to form a solution. Some CoCl2β€’6H2O also enters and now the moisture content is directly reflected in the color of the solution.
    This was filmed on a rainy day with some dry periods, and we see periods of crystal growth (β›…) and periods of crystal dissolution (🌧️) , remodeling the shape of the grains πŸ’Ž.

  7. CuCl2 & LiCl βš—οΈ πŸ§ͺ πŸ’Ž πŸ”¬
    anhydrous CuCl2 is a brown substance, which progressively turns green (and then blue) upon pickup of moisture. The CuCl2 we start with here has already developed quite a few green patches and is clearly not as dry as it could have been. Upon addition of highly deliquescent LiCl, we soon recover a brown color. 1/2
