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.
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 ...
Wood products treated with ACQ preservative were commercially produced in Canada for the first time in 2004. [ 4 ] [ 1 ] ACQ became a widely used wood preservative after concerns were raised about possible environmental contamination by chromium and arsenic from wood treated with chromated copper arsenate (CCA), through contact (especially in ...
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.
Chromated copper arsenate (CCA) is a wood preservative containing compounds of chromium, copper, and arsenic, in various proportions. It is used to impregnate timber and other wood products, especially those intended for outdoor use, in order to protect them from attack by microbes and insects. Like other copper-based wood preservatives, it ...
Radiography reveals the type, condition and density of the wood, as well as any pest damage or activity. [18] [19] Furniture and Larder Beetles [20] can burrow into wood compromising its internal structure and should be treated before proceeding with the restoration. IR, raking light photography, and low-magnification observation are useful in ...

Masonite, also called Quartboard or pressboard, [2] is a type of engineered wood made of steam-cooked and pressure-molded wood or paper fibers. The fibers form a stiff, dense material in a range of weights. [3] The process was formulated and patented by William H. Mason. [4]
