This mixed media sculpture uses black gesso as the background..
Gesso is a thick chalky primer that can be painted onto paper or fabric to provide a rough-textured surface. There are two categories, oil or acrylic, and both generally come in black, white and clear varieties. Both types stick to most surfaces, including wood, canvas, paper and metal. However, if you will be using oil paints, you should only use oil-based gesso, and the same goes for matching acrylic gesso with acrylic paints. While oil paint will not suffer so much from being painted on acrylic gesso, it does not work in reverse. Acrylic paint will not adhere permanently to oil gesso, and will eventually peel off.
It can also serve countless other purposes, since it also makes a good glue, transfer medium, modeling paste, glaze, and more.
As gesso is an Italian term, it is pronounced with a soft ‘g’, as in ‘jesso’.
