Emery paper is smooth fine black sandpaper, used for fine sanding metal. It has a really interesting texture that can take media such as pastel and paint.
In my work on Assignment 5 I discovered some ways of using it for quite dramatic images.
Some of the accidental textures already on old emery paper from earlier sanding and photographing light shining on new emery sheets gave some quite dramatic effects when scanned – particularly the explosion from the mouth with aeroplanes in the background.
Emulsion on emery paper
Emulsion paint made flat shape images that retained the brush strokes, and can also be scratched into.
