Once a wooden sculpture has been dehydrated cracks will appear, where even exposure to high relative humidity will not make the cracks close up entirely. However, conservators can fill the cracks with a variety of materials to create a unified visual impression. What should I ask for when matting and framing works of art on paper? Mat board should be made from 100% rag or lignin-free cellulose. Sometimes those labelled as "museum board" or "conservation board" are not of the highest quality. Alkaline buffered boards are not sufficient if the board contains wood pulp. Photographs should not be matted with alkaline buffered boards as some prints are adversely effected by alkalinity. Hinges are used to attach the work of art to the backboard of the mat. They should be made of Japanese paper, and should be adhered with wheat starch paste. Pressure sensitive adhesive tapes and pre-gummed tapes should not be used. Photographs are often attached to the mat with photo corners.

Frames constructed of wood or metal are generally stable; the adhesives, padding, and coverings made of twentieth-century materials may be less permanent. Once some types of synthetic fabrics and fillers have begun their deterioration, there is nothing at this time that will reverse it, but it can be slowed down. For furniture, just as for all other types of art objects, reduce exposure to light, especially ultraviolet radiation, which seriously damages textiles, plastics, and dyes. Handle the furniture from its most stable and widest area. Simple preventative measures such as felt pads and coasters will help avoid scratching plastic and surface finishes, which are difficult and expensive to restore. Commercial cleaners and waxes should not be applied to surfaces because they may contain abrasives and solvents that will harm the finish.
