Soft Pastels and Fade Resistance: Debunking Myths and Best Practices

Soft pastels have long been a beloved medium among artists due to their vibrant colors and versatility. However, many common misconceptions exist regarding the care and preservation of these delicate artworks, particularly around their fade resistance and sealing techniques. This article aims to clarify these myths and provide practical tips for protecting your pastel masterpieces.

Myth Busted: Do Soft Pastels Fade and Need Sealing?

While soft pastels can be delicate and prone to smudging, the idea that they require sealing to prevent fading is widely disputed. In fact, many brands of hairspray, which are often suggested for sealing pastels, can yellow and even damage the artwork over time. This is particularly concerning since not all hairsprays are acid-free, and some can be detrimental to the surface of your pastel paintings.

After extensive research, I tested various fixative products according to the manufacturers' instructions and observed the results. My findings highlight a significant issue with using fixatives on pastel artwork. Not only did these fixatives often damage the appearance and texture of the pastels, but they also caused significant harm to the paper support. The curing process, on the other hand, proved to be a free and more effective method to protect pastels against smudging and other damages.

Understanding the Curing Process

The curing process involves simply allowing the pastel painting to remain unframed for a few days, ideally in a moderately humid environment. This humid condition allows the gum tragacanth binder in pastels to become more adhesive without damaging the surface. According to my research, the curing process not only prevents smudging but also provides more protection against future smudging than using fixative. This method is simple, cost-free, and highly effective.

Best Practices for Preserving Your Pastel Artwork

Even after curing, there are steps you can take to further protect your pastel paintings. Here are some practical tips:

Let It Cure: If possible, allow the painting to cure before framing or storing. This ensures the pastels are properly set and less likely to smudge. Lightly Tap the Back: After completing a painting, tilt it downward and lightly tap the back to remove any loose pastel particles that would otherwise fall off later. Blending Technique: Use a gentle blending technique to reduce excess dust and improve adhesion to the surface, thereby minimizing potential smudging. Framing Safely: Frame the painting behind glass to prevent direct contact with air and potential smudging. Alternatively, store the painting until later, ensuring it is stored in a safe and dry place. Proper Storage: Wrap the painting in glassine or grease-proof baking paper. Use acid-free tape to secure the wrap to itself in the back or directly to the back of the artwork. Store the painting in an archival storage box to protect it from dust and humidity.

Conclusion: Embrace the Resilience of Soft Pastels

Soft pastels are more resilient than many artists give them credit for. With proper care and attention to detail, you can ensure your pastel paintings remain vibrant and beautiful for years to come. Remember, curing your paintings is a free and effective method to protect them from smudging and other damages. Happy painting!
