In 1956, when Belgian artist Pierre Cordier first wrote a dedication in nail polish on a piece of photographic paper, he merged the gestural act of painting with the chemical processes of darkroom printing. Usually, great care is taken to eliminate chemical contamination and light leaks etc. To make a chemigram however, the volatility of the photographic process is exploited to create and preserve the complex visual manifestations of chemical interactions.
