Oil storage of light, temperature and humidity have what demand is there

Light, especially the ultraviolet light can cause some color change and a variety of material degradation. Sun paintings" > oil painting media (linseed oil) over time has gradually become the tendency of yellow, yellowing speed in completely free of light would be faster, so oil storage space needs certain light. Can choose weak dispersion natural light, low wattage of incandescent lamp, low uv fluorescent lamp or uv filter sets of common fluorescent lamp.
In an ideal situation, painting can't touch the ultraviolet irradiation. If can't completely blocked, ultraviolet light by no more than 0.000075 watts per lumen (Sunrise paintings). Incandescent lamp produces little ultraviolet ray, but produce a certain quantity of heat. In the distance is too close or projection condition of uneven, also can make oil painting for excessive heating or heating uneven and deformation. Frame lights and spotlight should not be used.
About the problem of temperature and humidity, under normal circumstances, a certain temperature or humidity is not the main reason for the damage caused by oil painting, but this both changes. Storage space will need the change to the low, and the temperature and humidity of exhibition space remain consistent. High temperature lead to Side paintings has become feeble, easy with grey. Low temperature lead to oil painting become fragile, easily damaged in handling. The right temperature should be in the eighteen - 22 degrees Celsius. The correct relative humidity is 45-55%, maintain the stability of the relative humidity of wood oil painting is especially important.
