Museums that house Renaissance oilpaintings typically store them in environments that are carefully kept within narrowmargins of temperature and humidity to inhibit any deterioration. Laboratorytests have shown that the kind of oil paint used in these paintings actuallyadjusts to climatic changes quite well.If, as some museum directors believe,paint is the most sensitive substance in these works, then by relaxing thestandards for temperature and humidity control,museums can reduce energy costswithout risking damage to these paintings. Museums would be rash to relax thosestandards, however, since results of preliminary tests indicate that gesso, acompound routinely used by Renaissance artists to help paint adhere to thecanvas, is unable to withstand signifi cant variations in humidity.
