Practice question · Sort into groups
Sort each material by the light limit that is usually applied to it.
Groups: Commonly limited to about 50 lux · Commonly allowed 150 to 200 lux · Not usually light-limited
- A bronze cast
- A carved marble relief
- A dyed textile hanging
- An egg tempera panel
- An oil painting on canvas
- A watercolour on paper
Hints
- Two of the six are dyed or paper-based and are the most vulnerable.
- Two of them are not damaged by light at all in ordinary conditions.
Show the answer
Commonly limited to about 50 lux: A watercolour on paper, A dyed textile hanging
Commonly allowed 150 to 200 lux: An oil painting on canvas, An egg tempera panel
Not usually light-limited: A carved marble relief, A bronze cast
Why
The grouping is by vulnerability of the colourant and the substrate rather than by prestige, and the figures vary between institutions. What does not vary is the reason: light damage is cumulative and irreversible, so the limit is really a decision about how many years of showing the object is allowed.
