Ultraviolet

Ultraviolet

Definition

Ultraviolet (UV) refers to the portion of the light spectrum with wavelengths shorter than visible light, which can cause fading, discoloration, and degradation of artwork over time.

Characteristics

• Invisible to the naked eye but can penetrate glass, acrylic, and other glazing materials.
• High-energy UV rays accelerate chemical reactions in pigments, paper, and textiles.
• Responsible for photodegradation in artwork, including fading and yellowing.

Applications in Framing and Preservation

• UV-filtering glass or acrylic is used to protect framed artwork.
• Conservation framing materials often include UV-blocking coatings to reduce exposure.
• Placement of artwork away from direct sunlight is recommended to minimize UV damage.

Best Practices

• Always use UV-protective glazing for valuable or sensitive artwork.
• Monitor lighting levels in display areas, avoiding prolonged exposure to sunlight or strong artificial light.
• Combine UV protection with acid-free, archival materials for maximum preservation.
