A picture drawn by a crayon made from ground coloring matter mixed with gum producing a soft, pale shade of colors. The ground coloring matter will shed from the paper and is easily smudged if touched. We recommend raising the top mat from the pastel so any loose material will fall under the mat instead of on top - this is called creating a pastel tray.
- Matting should be used when framing a pastel so the glass touch the chalk
- Plexiglass should not be used as a glazing because the static charge from the plexi will pull the chalk of the paper
