Oil On Canvas: Painting Conservation 101
Summary
Conservation involves extending the life of artwork through remedial attention. This process often includes adding new material, which can be visible or invisible, to restore the piece's unity.One common issue observed on paintings is craquelure, a fine web of cracks on the surface. A painting comprises several layers:
1. Stretcher Bars: The framework covered by canvas.
2. Canvas: Coated with a sizing medium to prepare for painting.
3. Gesso: A ground layer applied over the sizing.
4. Paint: Layered on top of the gesso.
5. Varnish: A protective final layer.
Ideally, these layers dry evenly. Disruption in their harmony necessitates conservation. Changes in temperature or humidity can cause expansion and contraction, leading to damage. Even with controlled conditions, transportation vibrations can harm the layers.
Craquelure occurs when the canvas reacts to climate changes by shrinking or swelling, causing stress that differs from the ground or paint layer. This can lead to cleavage, where the paint lifts from the canvas.
When craquelure is age-related, it’s usually left undisturbed unless it escalates to cleavage; in such cases, a professional conservator is needed.
Another common issue is a slack canvas, indicating excess movement. Check the stretcher bars. If fixed with glue or nails and not adjustable, your painting is on strainer bars, not stretcher bars. Stretcher bars have keys (wooden wedges) or metal elements for adjustments. A canvas on strainer bars for too long can rip as it becomes brittle.
Yellowing or darkening varnish is another noticeable problem. Every 25 years, review paintings for varnish reapplication. A professional must first remove the original varnish.
