| Discovery | [cacher] |
I have left very used ferric chloride in plastic recipient containing Ferric Chloride for many months,
and when I decided to clean it up, I discovered that thousands of small green crystals had formed in
it.(Click on the picture to see closer. Sorry for the bad image quality.) |

Here are a few closeups of the crystals:
 I think those crystals are very pretty. They are transparent, very long and fine. Their color reminds me of the artificial kryptonite seen in one of the Superman movies. |
| Microscope | [cacher] |
| I have dissolved a few crystals in a small quantity of water, and looked at it with a microscope.
New crystals have formed again. Here are pictures taken with back lighting: 
A some places, the crystals were so thick that light would not pass through. I tried lighting from the other side, and it gave nice results: 
 
 As we can see, the crystals look the same as the bigger ones in the microscope, but they are of course smaller. |

| I would like to know what is the exact composition of those crystals. I think it must be
copper oxide or something similar. If you can tell me more, write me. raph@raphnet.net. Thank you. |
