Protecting Soft Pastel Paintings: A Comprehensive Guide

Soft pastel paintings are delicate works of art that require special care to maintain their vibrancy and longevity. This guide will explore the best methods for protecting pastel paintings, including the use of appropriate fixatives and proper framing techniques. We'll also delve into the history and usage of unique fixatives such as SpectraFix and DIY casein solutions, ensuring your artwork remains in pristine condition.

Introduction to Protecting Soft Pastel Paintings

Soft pastels are a popular medium for creating vibrant and detailed artworks. However, they are susceptible to smudging, becoming dirty, and losing their color intensity over time. Proper protection is crucial to preserve the integrity of these delicate pieces. In this article, we will discuss the best practices for safeguarding your pastel paintings, including the use of appropriate fixatives and framing methods.

Using Fixatives to Protect Soft Pastel Paintings

Fixatives are essential for protecting soft pastel paintings. Unlike gloss fixatives, there are non-glossy options specifically designed for pastel that preserve the vibrant color intensity and protect the work from smudging without darkening or altering the pastel's appearance. One of the most notable and historically significant fixatives used by artists like Edgar Degas is based on casein and ethanol. This fixative is water-based and has been proven to work well for preserving pastel paintings.

How to Use Casein and Ethanol Fixative

To prepare or buy a casein and ethanol fixative, follow these steps:

Ingredients: Casein, ethanol, and optionally water or other alcohol-based solutions like vodka or grain alcohol. Preparation: Mix the casein with the ethanol in the desired ratio. You can find different formulas online for specific ratios and concentrations that work best for your pastel paintings. Watercolor Paper: Use watercolor paper as it's more compatible with water-based solutions. Application: Apply the fixative carefully, and it's a good idea to do some tests first to understand how it behaves on your specific paper and pastels.

The casein and ethanol fixative, also known as SpectraFix [original milk casein formula], has the advantage of being less toxic. Edgar Degas used this fixative generously in between layers, preventing smudging and ensuring the top layers remained intact. He would leave the last highlights unfixed to preserve their clarity and vibrancy.

Framing Soft Pastel Paintings for Protection

In addition to using fixatives, proper framing is a crucial aspect of protecting soft pastel paintings. Frame the painting behind a protective glass to safeguard it from dust and physical damage. Plexiglass is a great option as it is more durable than regular glass and less prone to breakage. Museum glass is even better if you have a fine work of art that you want to display prominently.

Conclusion

Proper protection and care are essential for preserving the beauty and longevity of your soft pastel paintings. By using the right fixatives such as casein and ethanol solutions and framing your artwork behind protective glass, you can ensure that your pastel paintings remain in excellent condition for years to come.
