Some of the liquid is drawn into the wood as the result of capillary action before the spray runs off or evaporates, but unless puddling occurs penetration is limited and may not be suitable for long-term weathering. By using the spray method, coal-tar creosote, oil-borne solutions and water-borne salts (to some extent) can also be applied.
Quercus georgiana leaves Brown winter leaves on Georgia oak. The shiny green leaves are 4–13 centimeters (1 + 1 ⁄ 2 –5 inches) long and 2–9 cm (1– 3 + 1 ⁄ 2 in) wide, with a 0.6–2.3 cm (1 ⁄ 4 –1 in) petiole, and five irregular, pointed, bristle-tipped lobes; they are glabrous (hairless), except for small but conspicuous tufts of hairs in the vein axils on the underside.
Fumed oak choir stalls at Clonfert Cathedral, Ireland. 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 bulk of water contained in the cell lumina is only held by capillary forces. It is not bound chemically and is called free water. Free water is not in the same thermodynamic state as liquid water: energy is required to overcome the capillary forces. Furthermore, free water may contain chemicals, altering the drying characteristics of wood.
Tovex, a form of water gel explosive. A water-gel explosive is a fuel-sensitized explosive mixture consisting of an aqueous ammonium nitrate solution that acts as the oxidizer. [1] Water gels that are cap-insensitive are referred to under United States safety regulations as blasting agents. Water gel explosives have a jelly-like consistency and ...
Also known as the Jackson Oak, the tree is at the corner of South Finley and Dearing Streets in Athens, Georgia, US. The original tree, thought to have started life between the mid-16th and late 18th century, fell in 1942, but a new tree was grown from one of its acorns and planted in the same location.

Bog-wood may come from any tree species naturally growing near or in bogs, including oak (Quercus – "bog oak"), pine , yew , swamp cypress and kauri . Bog-wood is often removed from fields and placed in clearance cairns. It is a rare form of timber that is claimed to be "comparable to some of the world's most expensive tropical hardwoods".
