Artist Johan Falkman, a renowned sculptor and painter, contacted me in 2016 after he had made a bronze bust of famous Malmö entrepreneur Percy Nilsson. Both the artist and the client wanted an unusual patina, and not the warm brown most commonly used. I made several patination samples, ranging from light to dark greens, to light blues and almost black, and they selected one. The bust (unpatinated above, left) was patinated to match it as closely as possible. The chosen, rectangular sample can be seen below, right, immediately under the final result.
