I always start off my Intro to J&M course with annealing and then we move into some surface embellishment samples. The samples above are 2"x2" squares of copper that have been either roller printed or etched. The students bring in random materials to emboss against the copper as it is rolled through the rolling mill. For the etching sample they use sharpie, fingernail polish, asphaltum, or p-n-p blue paper for the resist. It's really amazing what is possible with very little effort. I've never taken images of the student samples; not sure why? Anyway, they can use these samples to test techniques they might want to use in the creation of their assigned project piece.
