Waterlogged wood is a wooden object that has been submerged or partially submerged in water and has affected the original intended purpose or look of the object. Waterlogged wood objects can also include wood found within moist soil from archaeological sites, underwater archaeology, maritime debris, or damaged wood objects.
Because of the composition of wood, careful control of humidity is a factor in preventive conservation. If the relative humidity is too low the wood will release some of its moisture into the air and dry out. Conversely, if the relative humidity is too high, the wood absorbs water from the air and expands.
Furniture conservation and restoration can be divided into two general areas: structure and finish. Structure generally relates to wood and can be divided into solid, joined, and veneered wood. The finish of furniture can be painted or transparent. [1] Furniture has existed throughout all the years of human existence.
Water-based lacquers are used extensively in wood furniture finishing as well. One drawback of water-based lacquer is that it has a tendency to be highly reactive to other fresh finishes such as quick-dry primer (excluding waterborne lacquer primers), caulking and even some paints that have a paint/primer aspect.
Wood is a very absorbing material based on its environment. Thus, depending on the amount of water that is exposed in the air, the wood can expand and contract easily, changing the physical condition of the object. [19] This is the reason why wood material needs to be kept in a high controlled and consistent temperature and humidity levels.
The result of the decomposition of cellulose and lignin will increase in the space between cells and the molecules within cells, this will render the wood to a more porous and permeable to water. All of the wood's cavities will be filled with water, and the absorbed water and the remnants of the lignin will maintain the original form of the ...
Water can come from roofs leaking during rainstorms, floods, fire sprinkler systems, or broken pipes. [7] It can soften and destroy the bone, antler, or horn if it becomes waterlogged. Mold and mildew growth can cause further damage. If the water in the crevices or pores of the bone, antler, or horn were to freeze, it would crack the object.
Changes in wood moisture content can result in swelling and shrinkage of wood which can stress and crack coatings. Both problems can be avoided by storing wood indoors in an environment where it can equilibriate to a recommended moisture content (6 to 8%) that is similar to that of the intended end use of the furniture.
