29 - Miedź - Bo srebrny kolor jest dla plebsu

Hello again. Here's another painstakingly crafted production. As usual, it's clumsy and not very funny, but it's full of obvious things and a few experiential lessons. Due to its length and deviating from the subject matter, only three pages of the nearly six-page script remain, but I think the film is still quite worthwhile. The flotation process could always be discussed in more detail in a separate article. This time, I'll add some sources: "Chemical Technology.
