Pastel is an art medium composed of pure powdered pigments. Dry pastels are soft and velvety. By their nature they have little binder and are very fragile, as the pastel is loosely bound to the paper support. They are vulnerable to abrasion and lose if their surface is not protected. Their ideal protection is to be framed. The frame seals should be secure to prevent dust and debris from entering.
Part of the re framing is to sealing the artwork within the frame in a package. This is a detailed shot of a corner showing a protective foil being wrapped around the edge of the package, followed by aluminium tape to double seal the edges.
