You can occasionally find this substance on eBay. Other than that it is pretty hard to come by.
"Copper(II) acetate was historically prepared in vineyards, since acetic acid is a byproduct of fermentation. Copper sheets were alternately layered
with fermented grape skins and dregs left over from wine production and exposed to air. This would leave a blue substance on the outside of the sheet.
This was then scraped off and dissolved in water. The resulting solid was used as a pigment, or combined with arsenic trioxide to form copper
acetoarsenite, a powerful insecticide and fungicide called Paris Green or Schweinfurt Green."
Thanks, when I made Copper Acetate a few months ago, I did so after finding out it was also a widely use pigment. I found this too, on the wikipedia
page, but again that article is paywalled off.
I also found out, that I could make either Paris green, by combing it with Copper Acetate, or Scheele's Green, by combining it with Copper Sulfate.
The LD50 for man is around 1,5 g for a 70 kg person. I wouldn't worry too much. |
