A Critical Examination of Contemporary Commercially Primed Canvases

In the ever-evolving world of art, materials and techniques are at the heart of every painting. For contemporary painters, the choice of canvas is as crucial as the brush strokes they apply. Anne Carter and her team, in their paper “Investigating Commercially Primed Contemporary Artist Canvases,” meticulously analyze the materials used in commercially primed canvases. This review highlights their findings and offers practical insights for artists.

Commercially primed canvases are common supports for contemporary painters. Such canvases are convenient and often affordable. However, the product information available for artists to inform purchase choice or their aging characteristics is limited and often unavailable.

The Study’s Scope and Methodology of Commercially Primed Canvases

The study analyzed fifty-three commercially primed canvases from Australian and Singaporean suppliers. The canvases, representing nineteen brands, underwent rigorous testing to identify their fiber, priming binder, pigments, and fillers. These tests included optical microscopy, ATR-FTIR, Py-GCMS, XRF, Raman spectroscopy, and SEM-EDS, among others.

Findings on Priming Materials

Synthetic Polymers and Their Prevalence

The study revealed that synthetic polymers are predominant in contemporary commercially primed canvases. Of the fifty-three samples, forty-nine contained synthetic polymer binders. Styrenated-acrylic was the most common, followed by acrylic and acrylic-PVAc binders. The presence of these materials reflects a shift from traditional oil-based primers to synthetic alternatives, largely due to their cost-effectiveness and versatility.

Variability in Priming Layers of Commercially Primed Canvases

The analysis identified four primary priming stratigraphies. These varied from single layers of irregular thickness to multiple layers with varying compositions. Notably, thirty-two percent of samples had single priming layers, while the rest exhibited double layers with combinations such as acrylic over styrenated acrylic or oil over acrylic-PVAc. This variability highlights the lack of standardization in the production of commercially primed canvases.

Impact on Conservation and Longevity

Sensitivity to Environmental Conditions

One significant finding was the sensitivity of these primed canvases to environmental conditions. Some exhibited stretchiness, discoloration, and unpredictable responses to humidification and heat. This has profound implications for conservation, as these materials may not withstand traditional conservation treatments. The presence of styrene, in particular, raises concerns due to its instability under UV radiation, which can lead to yellowing and cracking.
