Making Scrap Copper into Glow Powder
In this video I discuss and make a few beautiful fluorescent complexes from some scrap copper and the pyridine from last week. Two colors of this complex are possible (yellow and green) but unfortunately the green version isn't very stable and breaks down as it dries into the yellow version.
This is one of my safer projects, but do keep in mind that pyridine is highly toxic (and smells horrid)
NOTE: After doing more reading, I believe that the green complex is a dimer, and it basically looks like a tetrameric "square" of copper and iodine, with two pyridine molecules coordinated to each copper.
Cu₂I₂(Py)₄
