See link to an interesting site discussing Archival and Longevity Qualities of Eco Materials in Art
For archival longevity in artwork, 100% cotton or cotton and linen rag paper are the preferred choices. These materials are known for being acid-free, lignin-free, and durable, ensuring the artwork resists yellowing, fading, and deterioration over time.Here’s why these fibers are so good for archival purposes:
- Acid-free and Lignin-free: These papers are free from acids and lignin, which are major contributors to paper deterioration.
Durable Fibers:
Cotton and linen have long, strong fibers, making them more resistant to degradation than wood pulp-based papers.
pH Balanced:
Archival paper is typically pH balanced, further enhancing its longevity.
Resistant to Yellowing and Fading:
These properties help to ensure the artwork retains its original vibrancy and appearance over time.
Suitable for various art media:
These papers can be used for a wide range of art media, including oil painting, watercolors, and more.
- Other Considerations:
- Storage: Proper storage conditions, such as a cool, dry, and dark environment, are crucial for preserving artwork made on archival paper.
Acid-free materials:
When storing or framing artwork, use acid-free materials like mat boards and adhesives to avoid further damage.
UV protection:
If displaying artwork, use UV-resistant glass to help prevent colors from fading
