Why are many important historical artefacts locked away and rarely displayed even though they are very well protected (climate control boxes etc)?
There are a number of reasons why climate-controlled storage is often used to protect important historical artifacts. One of the most important practices to preserve artifacts is to keep their environment stable [1]. Large fluctuations of temperature and humidity are dangerous and can cause items to undergo damage such as photos sticking together, wood furniture to warp, or leather goods to crack [3]. Museums need a functioning HVAC system to keep the climate controlled and safe [1]. Air pollutants, including particulates, need to be controlled as well [1]. Climate-controlled storage units use heating and cooling units to keep the storage space at a safe temperature, usually at a level above freezing and below 90 degrees Fahrenheit [2]. If you are storing wine, keep in mind that your bottles need to be kept under even more controlled conditions [3]. Units that also offer humidity control keep humidity levels around 55 percent, according to the SSA [3]. Humidity is particularly dangerous to a variety of items and can cause photos to stick together, or wood furniture to warp, or leather goods to crack [3]. Electronics, artwork and items such as pianos also may sustain damage from humid environments [3]. If you own an item that’s especially sensitive to humidity, search for a storage unit
In general, historical artifacts are not displayed to protect them from damage but rather to minimize light exposure so that they can be displayed for a limited time [1]. Limiting exposure helps to protect the item for a longer period of time [1]. There are some items, such as family treasures, that hold a special meaning for multiple generations and are treated more like heirlooms rather than decorations [3]. In cases like these, limiting exposure helps to ensure that the items are treated with the respect they deserve [3].
