Rosewood (timber)
Rosewood refers to any of a number of richly hued timbers, often brownish with darker veining, but found in many different hues.[1] All genuine rosewoods belong to the genus Dalbergia. The pre-eminent rosewood appreciated in the Western world is the wood of Dalbergia nigra. It is best known as "Brazilian rosewood", but also as "Bahia rosewood". This wood has a strong, sweet smell, which persists for many years, explaining the name rosewood.[2] Another classic rosewood comes from Dalbergia latifolia known as (East) Indian rosewood or sonokeling (Indonesia). It is native to India and is also grown in plantations elsewhere in Pakistan (Chiniot). Madagascar rosewood (Dalbergia maritima), known as bois de rose, is highly prized for its red color

Allergic Response
An allergic response is a hypersensitive immune reaction to a substance that normally is harmless or would not cause an immune response in everyone. An allergic response may cause harmful symptoms such as itching or inflammation or tissue injury. Allergies are an abnormal immune reaction. The human immune system is designed to protect the body from potential harm and in people who have allergies the immune system will react to allergens (substances that trigger an immune response). The immune system will produce immunoglobulin E, IgE, antibodies for each allergen

Marimba
The marimba (/məˈrɪmbə/) is a percussion instrument consisting of a set of wooden bars struck with yarn or rubber mallets to produce musical tones. Resonators or pipes are suspended underneath the bars to amplify their sound. The bars of a chromatic marimba are arranged like the keys of a piano, with the groups of two and three accidentals raised vertically, overlapping the natural bars to aid the performer both visually and physically. This instrument is a type of idiophone, but with a more resonant and lower-pitched tessitura than the xylophone. A person who plays the marimba is called a marimbist or a marimba player. Modern uses of the marimba include solo performances, woodwind and brass ensembles, marimba concertos, jazz ensembles, marching band (front ensembles), drum and bugle corps, indoor percussion ensembles, and orchestral compositions

Recorder (musical Instrument)
The recorder is a family of woodwind musical instruments in the group known as internal duct flutesflutes with a whistle mouthpiece, also known as fipple flutes. A recorder can be distinguished from other duct flutes by the presence of a thumb-hole for the upper hand and seven finger-holes: three for the upper hand and four for the lower. It is the most prominent duct flute in the western classical tradition.[1] Recorders are made in different sizes with names and compasses roughly corresponding to different vocal ranges. The sizes most commonly in use today are the soprano (aka "descant", lowest note C5), alto (aka "treble", lowest note F4), tenor (lowest note C4) and bass (lowest note F3). Recorders are traditionally constructed from wood and ivory, while most recorders made in recent years are constructed from molded plastic. The recorders' internal and external proportions vary, but the bore is generally reverse conical (i.e

Cue Stick
A cue stick (or simply cue, more specifically billiards cue, pool cue, or snooker cue), is an item of sporting equipment essential to the games of pool, snooker and carom billiards. It is used to strike a ball, usually the cue ball. Cues are tapered sticks, typically about 57–59 inches (about 1.5 m) long and usually between 16 and 21 ounces (450–600 g), with professionals gravitating toward a 19-ounce (540 g) average. Cues for carom tend toward the shorter range, though cue length is primarily a factor of player height and arm length. Most cues are made of wood, but occasionally the wood is covered or bonded with other materials including graphite, carbon fiber or fiberglass

Fountain Pens
A fountain pen is a writing instrument which uses a metal nib to apply a water-based ink to paper. It is distinguished from earlier dip pens by using an internal reservoir to hold ink, eliminating the need to repeatedly dip the pen in an inkwell during use. The pen draws ink from the reservoir through a feed to the nib and deposits it on paper via a combination of gravity and capillary action. Filling the reservoir with ink may be achieved manually, via the use of an eyedropper or syringe, or via an internal filling mechanism which creates suction (for example, through a piston mechanism) or a vacuum to transfer ink directly through the nib into the reservoir. Some pens employ removable reservoirs in the form of pre-filled ink cartridges.[1] According to Qadi al-Nu'man al-Tamimi (d

Furniture
Furniture refers to movable objects intended to support various human activities such as seating (e.g., chairs, stools, and sofas), eating (tables), and sleeping (e.g., beds). Furniture is also used to hold objects at a convenient height for work (as horizontal surfaces above the ground, such as tables and desks), or to store things (e.g., cupboards and shelves). Furniture can be a product of design and is considered a form of decorative art. In addition to furniture's functional role, it can serve a symbolic or religious purpose. It can be made from many materials, including metal, plastic, and wood. Furniture can be made using a variety of woodworking joints which often reflect the local culture. People have been using natural objects, such as tree stumps, rocks and moss, as furniture since the beginning of human civilisation

Wood Flooring
Wood flooring is any product manufactured from timber that is designed for use as flooring, either structural or aesthetic. Wood is a common choice as a flooring material and can come in various styles, colors, cuts, and species. Bamboo flooring is often considered a form of wood flooring, although it is made from a grass (bamboo) rather than a timber.[1] Solid hardwood floors are made of planks milled from a single piece of timber. Solid hardwood floors were originally used for structural purposes, being installed perpendicular to the wooden support beams of a building known as joists or bearers. With the increased use of concrete as a subfloor in some parts of the world, engineered wood flooring has gained some popularity. However, solid wood floors are still common and popular

Rosewood Oil
Rosewood oil is a valuable essential oil, especially in perfumery.[1] It contains the substance linalool, which has a number of uses.[2] The oil is extracted from the wood of Aniba rosaeodora and Aniba parviflora and possibly other Aniba species.[3][4] When it arrives at the distillery, the wood is chipped, and then steam distilled. Each tree yields about 1% oil by weight of wood. After a history of massive overharvesting and species depletion, efforts are underway to cultivate A

Overexploitation
Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource. The term applies to natural resources such as: wild medicinal plants, grazing pastures, game animals, fish stocks, forests, and water aquifers. In ecology, overexploitation describes one of the five main activities threatening global biodiversity.[2] Ecologists use the term to describe populations that are harvested at a rate that is unsustainable, given their natural rates of mortality and capacities for reproduction. This can result in extinction at the population level and even extinction of whole species
