Wear cotton or nylon gloves when handling historic paper, textiles, photographs, and wooden and metal objects. These oils and other surface substances are transferred to the object during handling. Human beings are one of the greatest threats to historic objects, not only due to surface compounds, such as oil, sweat and make-up that they carry on their skin, but also because we continue to use historic objects. Conduct regular inspections of historic objects that attract pests. Moths are attracted to protein fibers such as silk and wool. Roaches and silverfish are attracted to paper and books. Store historic memorabilia in an area that has a steady, constant humidity (45%–55%), and store or display historic materials away from heating and air conditioning vents.ĭifferent types of historic materials attract different types of pests. Organic objects in particular absorb and release moisture depending on the relative humidity of their environment and need a stable humidity. Humidity that is too low can cause objects to become brittle. Humidity that is too high encourages pests and mold growth on paper, textiles and parchment, and promotes rust on metal. Do not store in sheds, attics and basements. Store or display historic memorabilia in spaces that have climate-control systems (heating and air conditioning).

Too high or too low a temperature (or rapid temperature swings) can damage rubber, wood, metal, etc. Place furniture, antique quilts and other memorabilia out of direct sunlight and/or florescent light. Historic objects should be protected from excessive light levels, and especially from sunlight and florescent light, which contain high amounts of ultraviolet radiation-which is the most harmful form of light. Too much light speeds deterioration of photographs, textiles and printed or handwritten paper, furniture, etc. The following hazards are recognized as some of the most dangerous to historic memorabilia. The basic principle of preservation of historic memorabilia is DO NO HARM. Looking for a conservator? Check out our list of conservation resources below.
