The chemigram is a physico-chemical process discovered by Pierre Cordier in 1956. Black & white photo paper is first coated with a resist much like in the batik process, either a soft one like a glue or a hard one like an acrylic varnish. The resist can be incised with marks from various tools such as an Xacto blade. Then the paper is run through developer and fixer, back and forth, over and over. This part of the process can take seconds (with soft resists) to hours (with hard resists), during which time the laws of nature collaborate with the marks of the artist to create one-of-a-kind prints impossible to get with the artist’s hand alone. I revel in this unique collaboration with natural law made visible.
