Artwork can be damaged by improper art storage conditions. Sunlight, moisture, and temperature all can deteriorate your valuable collection.
The terms "art" and "artwork" consists of an incredibly wide variety of mediums, utilizing a practically limitless array of materials. For advice on conditions where a particularly unique or valuable piece of modern art is being displayed or hung, it may be best to consult the gallery where you purchased it. But generally speaking, avoid keeping artwork, such as a painting, near sources of heat or direct sunlight. Maintaining a relative humidity around 55% is often a good idea too. Use a humidifier or to increase humidity or a dehumidifier to decrease humidity. A humidity controller is often used for valuable collections. Comfortable indoor room temperature (68 to 72°F; 20 to 22°C ) is typically appropriate for artwork (since that's generally where art is shown, anyway). More importantly, avoid rapid changes in conditions. For transport or long-term storage of artwork, always do your research or hire an expert, since these represent common situations where permanent damage can occur.
