UV Rays

UV Rays

Definition

UV Rays are a form of electromagnetic radiation in the ultraviolet range, beyond the visible light spectrum. These rays can penetrate materials and cause fading, discoloration, or deterioration of artwork and other sensitive materials over time.

Characteristics

• Invisible to the human eye but can damage pigments and paper fibers.
• Found in sunlight and certain artificial lighting sources.
• Long-term exposure leads to irreversible fading and degradation of artworks.

Applications in Framing

• Mitigated using UV-filtering glazing, such as UV acrylic or UV-protective glass.
• Essential consideration for framing and displaying artwork in bright or sunlit environments.
• Used in preventative conservation strategies to extend the lifespan of artworks.

Best Practices

• Always choose UV-filtering materials for glazing valuable artwork.
• Limit direct sunlight exposure even with UV protection to further reduce fading.
• Combine with acid-free mats and backing boards for comprehensive preservation.
