I may have accidentally created copper cloride in addition to the Copper Acetate(WSDTY). I decided to just let the solution (made form Copper, vinegar, and salt) evaporate with a small fan speeding the evaporation for the last few weeks. The tallest copper acetate crystals started breaking the surface and then the surface of the liquid started to form a skin so I poured off the now green liquid into another jar. Copper acetate is blue, which is why the green solution seems to suggest that there is copper cloride.

Note the blue-green layer of copper carbonate below the dark copper acetate crystals. The green liquid on the left is what was left from evaporation (and I think is copper chloride) - next to another jar of copper acetate. The copper acetate crystals were covered in a thin layer of copper carbonate because last week I disturbed the solution and stirred up a cloud of copper carbonate accidantally. I rinsed them with vinegar and they cleaned nicely.

The largest crystal was just over 1 cm wide. These crystals were grown from a solution that started evaporating 5 years ago. The copper carbonate goo in the bottom needed a use so I added more vinegar to it and it formed the copper acetate solution three pictures up (next to the green copper chloride).
