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 ...
An example of the conservation of wood and how it has changed over time can be illustrated by the conservation treatments of a Kefermarkt altar. The earliest attempt at wood conservation is recorded as late as 1852–1855, A. Stifter treated the Kefermarkt altar in Austria with table salt in an attempt to protect the wood against pests.
Ammonia fuming is a wood finishing process that darkens wood and brings out the grain pattern. It consists of exposing the wood to fumes from a strong aqueous solution of ammonium hydroxide which reacts with the tannins in the wood. The process works best on white oak because of the high tannin content of this wood.

Table 2. Relative toxicities of chemicals [20] Boron-based compounds are toxic to fungi, but their effects on mammals are minimal. [11] However, conventional wood preservatives consist of the active ingredient and a solvent, and it is the organic solvents that seem to give more cause for concern.
During the wood treatment process, the water-soluble copper and the quaternary ammonium cations are immobilized by the formation of stable insoluble compounds with lignin, cellulose, and hemicellulose and other wood components. [2] The copper is the primary bactericide and fungicide agent.
While vinegar may be good for you, “it’s not a drug,” Johnston notes. As part of an overall healthy diet, “it’s going to have a more gradual effect on measures like blood sugar” than ...
