Are Sennelier Pastels Worth the Price? A Professional Review

What specific raw materials and manufacturing processes distinguish these pastels from mass-produced alternatives?

Sennelier utilizes a traditional manufacturing process that avoids the high-pressure extrusion methods common in industrial pastel production. Instead, the pigments are ground with a natural binder and allowed to air-dry, which preserves the structural integrity of the individual pigment particles. For example, the brand relies on a specific clay-based binder that remains flexible even after the stick has cured, allowing for a unique, velvety consistency that mimics the feel of raw pigment.

This process creates a distinct nuance in how the sticks behave. While most brands prioritize uniformity, these pastels vary slightly in density depending on the specific pigment's chemical properties. A heavy mineral pigment like cadmium yellow will feel denser than a light organic pigment like ultramarine blue. This inconsistency is not a defect but a direct result of minimizing additives to make sure the purest possible color output.

How does the high pigment-to-binder ratio affect the layering and blending capabilities of the medium?

The high pigment-to-binder ratio allows the pastel to release onto the paper with minimal friction, facilitating effortless glazing and optical color mixing. Many artists assume that because the sticks are soft, they must be used for thick, heavy impasto marks, but they are actually most effective when applied in thin, transparent veils. By using a light touch, you can layer multiple colors without clogging the tooth of the paper, keeping the final work luminous and preventing the dull, greyish look that occurs when binders are over-saturated.

In what ways does the unique softness of this brand influence the longevity and durability of a finished artwork?

The extreme softness of these pastels necessitates a deliberate approach to long-term preservation, as the high pigment load remains loosely adhered to the support.

1. Apply a high-quality glassine sheet over the finished surface to prevent accidental smearing or pigment transfer during storage.
2. Use a frame with a deep spacer to make sure the artwork never touches the glazing material directly.
3. Mount the work on a rigid, acid-free backing board to prevent the support from flexing, which could cause the brittle pigment layers to crack or flake off.
4. Keep the finished piece in a climate-controlled environment to minimize the expansion and contraction of the paper fibers.

Are there specific artistic techniques or substrates that yield the best results when using these professional-grade pastels?

Achieving professional results requires pairing these soft sticks with surfaces engineered to hold heavy pigment loads.

• Sanded paper: The abrasive surface acts like a file, pulling the pigment from the stick and locking it into the paper's texture.
• Pastel board: These rigid supports provide a consistent, non-warping base that prevents the pigment from shedding during the framing process.
• Canson Mi-Teintes: This specific paper features a distinct honeycomb texture that catches and holds delicate layers of color better than standard drawing paper.
• Glassine: Interleaving your work with this neutral paper protects the fragile, un-fixed surface from friction and atmospheric contaminants.

How do these pastels compare to other premium brands in terms of lightfastness and color saturation?

Sennelier pastels generally achieve superior lightfastness ratings, with the majority of the range earning the highest possible classification for color stability. Their saturation levels remain unmatched due to the absence of white filler, which often dilutes the intensity of cheaper alternatives.

Use these ratings to select pigments for work intended for long-term museum display.

What are the primary challenges artists face when transitioning to such highly pigmented and fragile pastel sticks?

Learning to control these pastels requires an adjustment in physical technique to accommodate their lack of structural rigidity.

• Finger pressure: Beginners often press too hard, resulting in broken sticks and wasted material that clogs the paper surface prematurely.
• Wrist motion: Developing a loose, flicking motion helps deposit color without crushing the delicate, air-dried structure of the pastel.
• Dust management: The high pigment volume creates significant airborne particles, requiring a dedicated workspace with proper ventilation or a localized dust collection system.
• Stick handling: Using a light grip or a protective sleeve prevents the heat from your hands from softening the binder further during long sessions.

Does the price point correlate with a measurable difference in the archival quality of the work over time?

The higher price point reflects the use of pure, lightfast pigments that resist chemical degradation and color shifting over decades. Cheaper brands often rely on fugitive dyes or excessive fillers that yellow or fade when exposed to ambient light.

Consult these benchmarks to determine if your project requires archival-grade materials for permanent collection.

Which professional settings or artistic styles derive the most significant benefit from a higher investment in pastel quality?

Yes. Artists working in fine art portraiture or landscape painting benefit most, as these styles require the high-density color transitions that only 100% pure pigment can provide. Using these sticks for large-scale work is particularly effective, as they cover significant surface area with just a single, light pass.
