Ensuring a good space is provided inside the
frame so that the pastel is kept well away from
the glazing.
After treatment the pastel portrait is
securely protected within its original
frame.
A false margin used to flatten the work is also used
to mount the pastel to a new archival backing.

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.
