Preserving |
Pastels must always be framed and glazed to best preserve them. Most acrylic sheeting is not satisfactory to glaze pastels because its static charge will attract pastel particles, a problem that is exacerbated when the plastic is rubbed (during cleaning, for example). To protect the surface of these fragile works, shatterproof glass with an Ultraviolet (UV) barrier is recommended.
Pastels must also be protected from mold and other forms of biodeterioration, problems to which they are vulnerable because of the organic binders in the crayons, the adhesives used in the mounting structure, and their paper supports. Environmental levels must be kept in a range of 68 to 72 degrees Fahrenheit and 48 to 52 percent relative humidity. High humidity can provoke staining; low levels can lead to desiccation of the support. For travel and transport, pastels should be framed and kept in a horizontal, face-up position. One of the greatest hazards to a pastel is vibration. This can be reduced by cushioning crates with ethafoam, or, for short distances, wrapping the composition in bubble wrap with the bubbles facing outward. Understanding the particular properties of pastel enhances our appreciation for the distinctive light and beautiful richness of color of the medium, qualities underlying its great acclaim in the eighteenth century. It also enables us to take the steps needed to preserve these fragile portraits so that we may continue to enjoy them and ensure their future in good condition. |
