Wood slabs can also become warped as a result of insufficient support from underlying shelf hardware (commonly referred to as sagging or bowing). [2] The types of wood warping include: bow: a warp along the length of the face of the wood; crook: a warp along the length of the edge of the wood; kink: a localized crook, often due to a knot
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 w
Wood decay describes wood in all stages of fungal attack, from the initial invasion of hyphae into the cell walls to the complete destruction of the wood. [10] Wood-inhabiting fungi are most common on timber piles above the water surface since the lack of oxygen below water inhibits fungal growth.
Apart from structural wood preservation measures, there are a number of different chemical preservatives and processes (also known as timber treatment, lumber treatment or pressure treatment) that can extend the life of wood, timber, and their associated products, including engineered wood. These generally increase the durability and resistance ...
The five common chemical agents that damage wood are: Light – Creates a chemical reaction within the cell walls of wood, leading to a change in color or texture; Acids – Cause wood to become brittle. Alkalies – Cause the fibers of the wood to separate and break down. Salts – Similar to alkalies, salts break down the fibers of wood.
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 ...
Mold is a probable consequence of water damage to parchment, especially when the object is not dried within 48 hours of the initial contact with water. [14] Heat: Heat in excess of the ideal storage conditions can cause damage to collagen structure, irreversible contraction and alteration of surface materials in parchment objects. [2] Light ...
Underwater logging is the process of logging trees from underwater forests. When artificial reservoirs and dams are built, large areas of forest are often inundated; although the trees die, the wood is often preserved.
