The Pros and Cons of Copper CookwareSerious Eats

Jan 07, 2021 · Copper was the first metal to be worked by human hands, and that history goes back a long, long time—about 11,000 years. That makes the human relationship with copper about as old as agriculture, though for several millennia we didn't do much with it beyond shaping it into decorative objects.

Sometimes, the crystal-like precipitates are later separated from the copper and used in pieces of fractal artwork. The solution at the end of the experiment is a characteristic blue colour. This is because of the presence of copper nitrate, which appears blue because of its ability to absorb the white light that passes through a solution.
