The most abundant polyphenols are the condensed tannins, found in virtually all families of plants, and comprising up to 50% of the dry weight of leaves. Tannins of tropical woods tend to be of a cathetic nature rather than of the gallic type present in temperate woods.Tannin in Tropical Woods. Doat J, Bois.

Lapachol is a natural phenolic compound isolated from the bark of the lapacho tree.Record, Samuel J.. "Lapachol" pages 17-19. In: Tropical Woods (1925). This tree is known botanically as Handroanthus impetiginosus, but was formerly known by various other botanical names such as Tabebuia avellanedae.

Record, Samuel J. Lapachol. Tropical Woods (1925), 1 7-9. Chemically, it is a derivative of naphthoquinone, related to vitamin K. Once studied as a possible treatment for some types of cancer, lapachol's potential is now considered low due to its toxic side effects.Oral toxicology studies with lapachol.

Typical air-dry samples have densities of approximately 1.30 g/cm3, and up to 1.42 g/cm3.Record, S. Tropical Woods, Vol. 8. 1926 () The tree reaches in height with oppositely arranged, emarginate leaves and small greenish flowers. The fruit is a drupe 5 to 7 mm long turning purplish red as it matures.

He used expensive materials such as marble, onyx, bronze, tropical woods etc. For the decoration of the staircase, Horta cooperated with the Belgian pointillist painter Théo van Rysselberghe. The Hôtel Solvay and most of its content remained intact thanks to the Wittamer family. They acquired the house in the 1950s and did the utmost to preserve and restore this magnificent dwelling.

The Portuguese settled on the offshore islands of São Tomé, Príncipe, and Fernando Pó, but were regular visitors to the coast. They named the Gabon region after the Portuguese word gabão — a coat with sleeve and hood resembling the shape of the Komo River estuary. Dutch, English, and French merchants came in the 16th century and, alongside the Portuguese, traded for slaves, ivory and tropical woods.

The boat was designed by Hugh Angelman and constructed from 1956 to 1958 in Costa Rica. She was originally constructed with sapele and purpleheart. Restoration has been done using, among other south American tropical woods, Hymenaea courbaril. In 1958, four men associated with the Quaker religion sailed toward Enewetok atoll in the Marshall Islands aboard Golden Rule with the goal of preventing atmospheric nuclear weapons testing.

Inlay in tropical woods, particularly satinwood, was an important element of Neo- classical furniture. In 1772–4 Cobb produced an ‘Extra neat Inlaid Commode’ and two stands en suite for Paul Methuen at Corsham Court, Wilts, which survive in situ. In 1772 he was implicated in the smuggling of furniture from France. His most extensive work was for the 6th Earl of Coventry at Croome Court, Worcs, between 1765 and 1773.

Tortoise shell, seashells, animal horn, pewter, silver, and exotic tropical woods gathered during the whaling journeys sometimes provided decorative accents. Shelburne Museum's scrimshaw collection offers a broad range of forms. A variety of teeth are decorated with whaling scenes, portraits, and patriotic motifs. A "Susan's tooth," one of a handful engraved in the 1830s by Frederick Myrick aboard the ship Susan, is among the earliest documented scrimshaw in existence.

Boxwood was a common material for the manufacture of recorders in the eighteenth century, and a large number of mid- to high-end instruments made today are produced from one or other species of boxwood. Boxwood was once a popular wood for other woodwind instruments, and was among the traditional woods for Great Highland bagpipes before tastes turned to imported dense tropical woods such as cocuswood, ebony, and African blackwood.

It was fitted with pedal attachments (to operate like an organ pedal-keyboard) and built with tropical woods that would acclimate to conditions there. Towards the end of the 19th century, the Pleyel firm produced the first chromatic harp. In the early 20th century, at the behest of Wanda Landowska, it helped to revive the harpsichord. Pleyel also pioneered the player piano with the Pleyela line of pianos.

The Indian market is accustomed to teak and other hardwoods that are perceived to be more resistant to termites, decay and are able to withstand the tropical climate. Teak wood is typically seen as a benchmark with respect to grade and prices of other wood species. Major imported wood species are tropical woods such as mahogany, garjan, marianti, and sapeli. Plantation timber includes teak, eucalyptus, and poplar, as well as spruce, pine, and fir.

The large meeting or deliberation room on the third floor was by the interior designer T. Nieuwenhuis. Its interior fittings are made of dark tropical woods such as mahogany, ebony and coromandel. During a renovation in 1972 the stained-glass windows were shortened, original wall coverings were redone in a lighter shade and the original wall lamps, ceiling and chandelier removed. The original chandelier, executed in openwork brass, was replaced in 1974.

The main early export was tropical woods such as cedar, oak, walnut and others. Much of this was exported to Europe. The Spanish galleons of Manila brought coconut trees to the area, which became the basis of the economy of the coast for some time. Few, if any, vestiges of the haciendas of the area remain, mostly because lasting constructions such as stone mansions or aqueducts were ever built, as they were in other parts of Mexico.

It is a heavy, hard wood with a somewhat coarse texture, often with an interlocked or wavy grain. The interlocked grain of this wood, like that of many tropical woods, can make it difficult to work. It is also a decorative exotic wood, used in a limited way for veneer, wall paneling, custom furniture, furniture trim, inlay bandings, marquetry, specialty items and turnery. It is also sometimes seen as stocks of shotguns and rifles or in exotic guitars.

Traditionally made of wood, carved signs allow for the most creativity in terms of painting, shape, and sculpture. Western red cedar and redwood (Sequoia sempervirens) is most common, although cherry and oak are also used along with a range of darker tropical woods. Wood requires regular maintenance and repeated coats of varnish or paint. More recently developed synthetic materials, notably high-density urethane (HDU), have been extremely successful, allowing the same quality and craftsmanship coupled with a much greater weather resistance.

Between the thirteenth and eighteenth centuries, before the introduction of turnips, Ilex aquifolium was cultivated for use as winter fodder for cattle and sheep. Less spiny varieties of holly were preferred, and in practice the leaves growing near the top of the tree have far fewer spines, making them more suitable for fodder. Ilex aquifolium was once among the traditional woods for Great Highland bagpipes before tastes turned to imported dense tropical woods such as cocuswood, ebony, and African blackwood.

Rosewood stockpile sits on a beach near Antalaha, awaiting export to China or Europe China is the largest consumer of tropical woods in the world. As of 2008, it imports 45 million cubic meters of tropical wood per year, a fourfold increase since 1998. Having depleted its own rosewood stands and those of nearby neighbors, such as Burma, Chinese timber importers have focused their attentions on Madagascar. As a result, nearly all of the rosewood exported from the SAVA Region is shipped to Chinese import companies.

In 1917 he became Professor of forest products, and in 1939 was made Dean of the school. Through field trips around the Americas (most notably Belize, Guatemala, Honduras, Colombia and of course the US) and help from correspondents all over the world, Samuel Record amassed a collection of some 41 000 identified wood specimens. Originally housed at Yale, the SJRw collection was moved in 1969 to the US Forest Service's Forest Products Laboratory. He was a founder of the International Society of Wood Anatomists and started publishing the journal Tropical Woods in 1925.

Because it stands up well to repeated handling and exposure to water, a common use is for gun grips and knife handles, and duck calls. It is very hard, fine textured, and dense, yet easily machined. The abundance of natural oils, however, causes the wood to clog abrasives and fine-toothed saw blades, like other hard, dense tropical woods. Besides its use on guns and knives, cocobolo is favored for fine inlay work on custom, high-end cue sticks, police batons, pens, brush backs, bowls, pipes, jewelry boxes, desktops and other expensive specialty items.

Garcilazo de la Vega records that the Chachapoyas' territory was so extensive that, (The league was a measurement that covered about 5 kilometers.) The area of the Chachapoyas corresponds to a region that was part of a mountain range and covered by dense tropical woods. It was named as the Amazonian Andes, to replace the former "mountain region". As fast as the population was growing, the forests of the Amazonian Andes were felled in order to extend the agricultural area. This resulted in destruction of the rain forest and desertification, since the climate and rain combined to make a soil of low fertility.

Excerpts of the inventory are briefly interpreted by G. de Bellaigue 1974:864. Most of the refined furniture bearing his stamp is in Louis XV style, employing crossbanded veneers of tropical woods rather than marquetry, and with sensitively-integrated gilt-bronze mounts that betoken close collaboration with the fondeurs-ciseleurs who made them, rather than purchases of stock mounts on the wholesale market.G. be Bellaigue (Bellaigue 1974:863) tentatively identifies three bronziers among the creditors at Joseph's death. About 1745 he married Reine Chicot, of a family of Parisian menuisiers, makers of carved panelling and seat furniture.

One of the characteristics that makes Hord’s work unique was his choice of the materials from which he created them. Besides the standard bronze, limestone, granite, cast stone, terra cotta, and the marbles used by other artists, Hord’s works appeared in various tropical woods such as mahogany, eucalyptus, ebony, lignum vitae, and rosewood, and in minerals such as obsidian, diorite, onyx and nephrite. His jade piece, Thunder, at 104 pounds, was reckoned to be the largest jade sculpture ever produced. What most of these materials have in common is that they are very hard and difficult to work.

Although Chinese demand constitutes the vast majority of the demand for Malagasy rosewood and other precious tropical woods, they are still popular in Europe and North America—particularly rosewood. Between January and April 2009, approximately 1.5% of the wood harvested in the SAVA Region and exported from Vohémar made its way directly to Europe in semi-finished form for the production of musical instruments and craft furniture. The tree species in these shipments consisted mostly of ebony, palissandre, faho, and andrapotsy. In some cases, the wood is shipped to China, where it is crafted into products that are eventually sold in the United States and Europe as high-end goods.

The market for thermally modified exterior products increased very rapidly as European consumers increasingly looked for alternatives to tropical woods from Asia, Africa and South America. A Turkish producer, Nova Wood, also started producing of thermally modified wood and became a minor player in European markets. In 2012, Brenstol established an affiliate in the U.S., Thermory USA and began to expand aggressively in markets around the world. The Thermory brand has become well-established in the U.S. and Canada, and has been shipped to over 55 countries around the world. In 2016, Thermory’s revenue was 29 mln euros, with 1.8 mln euros in profit.

Woods that are coarse textured such as oaks and other ring-porous hardwoods may need to be filled before they are finished to ensure the coating can bridge the pores and resist cracking. The pores in ring-porous woods preferentially absorb pigmented stain, and advantage can be taken of this to highlight the wood's grain. Some tropical woods, such as rosewood (Dalbergia nigra), cocobolo (Dalbergia retusa) and African padauk (Pterocarpus soyauxii), contain extractives such as quinones, which retard the curing of unsaturated polyester and UV-cured acrylate coatings, and so other finishing systems should be used with these species. thumb Planning for wood finishing also involves being aware of how the finishing process influences the end result.

The Spanish enslavement of Africans to the New Spain had been authorized by the Catholic Monarchs in 1501. As part of ending the War of the Spanish Succession 1713, the Spanish Crown granted the Asiento slaving contract for 30 years to the British South Sea Company, a monopoly in the slave trade of African slaves to the Americas. Besides continuing slavery, the contract had the unintended effect of allowing the English to trade large quantities of unauthorized goods and merchandise directly with the Spanish colonies as well. The longstanding British settlement at Laguna de Términos was another issue, which continued the illegal harvest of tropical woods, especially the Logwood trees, by the English.

While following traditional south German models, the company initially built instruments incorporationg modern technologies such as electric stop action. Cases had very contemporary designs, such as the organ in Cologne-Gremberg, set on a mushroom-shaped concrete pedestal, or in another organ that has free hanging steel frame with plexiglass used for the swell box and rollerboards, thus enabling a free view into the workings of the instrument. During the 1970s the firm abandoned the use of tropical woods and laminates in favour of solid woods, and electric action likewise was discarded in favor of mechanical action. While continuing to build new organs in the 1980s the firm began to devote attention to the restoration of older instruments, including organs of the South German Baroque, and Romantic instruments with valve chests and pneumatic actions.

Born in Switzerland, at 18 years of age, after completing a three-year curriculum in woodcarving, he answered an advertisement to work on the interior of the Episcopalian Convent of the Transfiguration in Glendale, Ohio. In 1935, he was recruited by the elegant Honolulu branch of the renown department store S. and G. Gump and Company to come to Hawaii and produce hand-carved home furnishings and decor. With his classical European training, his carving depicted lifelike tropical leaves and flowers artfully carved onto wood surfaces, contributing to the mid-century "Hawaiian Style." Working with tropical woods such as koa, mahogany, mango, kamani, and monkeypod, he carved sculptural wooden perfume containers, highly detailed room screens, trays and bowls, table and floor lamps, and figural art sculptures including Polynesian heads for sale in the store, and also produced custom woodworking and furniture such as tables, chairs, cabinets, sideboards, and bedroom suites, for homes and commercial interiors.
