The Problem With Measuring Only What Can Be Measured
Most research into better canvas was led by conservators and materials scientists, so it focused on what could be tested. Strength, stability, environmental response, fibre behaviour.
That work matters. Testing published by the Victoria and Albert Museum found that polyester fabrics showed no significant change in tensile strength after light exposure equivalent to roughly 80 years on museum display, and none after heat ageing at 60°C for three months followed by 80°C for two months.
Worth saying plainly: that study tested plain polyester fabrics rather than primed artist canvas, and it measured strength rather than how a surface behaves under paint. It tells you the fibre is stable. It does not tell you the canvas is good.
Because a canvas is not successful only because it survives. It has to work while it is being painted on. That part has to come from artists, and it is why they were involved here from the beginning rather than at the end.
