Forestry & Woods

Forestry and Woods

- Ebony wood: is a dense black wood, most commonly yielded by several different species in the genus Diospyros. Ebony is dense enough to sink in water. It is finely-textured and has a very smooth finish when polished, making it valuable as an ornamental wood.

Modern uses are largely oriented to making small items, such as crucifixes, and musical instrument parts, including black piano and harpsichord keys, violin, viola, guitar, double bass, and cello fingerboards, tailpieces, pegs, chinrests, and bow frogs. Many plectrums, or guitar picks, are made from this black wood. Traditionally, the black pieces in chess sets were made from ebony, with rare boxwood or ivory being used for the white pieces.

- Timber or Lumber is wood that has been processed into beams and planks, a stage in the process of wood production.Timber may be supplied either rough-sawn, or surfaced on one or more of its faces. Besides pulpwood, rough timber is the raw material for furniture-making and other items requiring additional cutting and shaping. It is available in many species, usually hardwoods, but it is also readily available in softwoods such as white pine and red pine.

- Woods are used for Construction, flooring, Furniture and utensils, arts....

- Charcoal: Charcoal is a light, black residue, consisting of carbon and any remaining ash, obtained by removing water and other volatile constituents from animal and vegetation substances. Charcoal is usually produced by slow pyrolysis, the heating of wood or other substances in the absence of oxygen. It is usually an impure form of carbon as it contains ash; however, sugar charcoal is among the purest forms of carbon readily available, particularly if it is not made by heating but by a dehydration reaction with sulfuric acid to minimise the introduction of new impurities, as impurities can be removed from the sugar in advance.

the uses of charcoal are Metallurgical fuel, Industrial fuel, Cooking fuel, Carbon source, Purification and filtration, Horticulture, Medicine.

- Rubber: Rubber is the name of a material which can stretch and shrink. It is a polymer. It can be either produced from natural sources (eg. natural rubber) or can be synthesised on a industrial scale. Lots of things are made from rubber, like gloves, tires, plugs, and masks. Natural rubber, also called India rubber or caoutchouc, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds plus water. Forms of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from certain trees. The latex is a sticky, milky colloid drawn off by making incisions into the bark and collecting the fluid in vessels in a process called "tapping".
