Utilitarian to upscale: Peroba rosa is on a straight and narrow path to greater popularity.[ILLUSTRATION OMITTED]Peroba rosa is one of the most commercially important timber trees TIMBER TREES. According to Blackstone, oak, ash, elm, and such other trees as are commonly used for building, are considered timber. 2 Comm. 28. But it has been contended, arguendo, that to make it timber, the trees must be felled and severed from the stock. 6 Mod. 23 Stark on Slander, 79. of Brazil, with uses that range from the utilitarian to the decidedly upscale. Peroba rosa is used in general construction and shipbuilding, joinery joinery, craft of assembling exposed woodwork in the interiors of buildings. Where carpentry refers to the rougher, simpler, and primarily structural elements of wood assembling, joinery has to do with difficult surfaces and curvatures, such as those of spiral , flooring, sash and doors, and interior trim. It is a popular choice for turnery and is used in furniture and cabinetry at all price points, from plain to high-end designs. Also known as rosa peroba, red paroba, amarello, palo, rosa and amargoso, to name a few, the species has been compared to European beech and American oak and shares many of the same uses, although because of its wide variation in strength--44 to 53 pounds per cubic foot--peroba rosa is not usually considered a candidate for steam bending applications. Aspidosperma peroba is the species often cited for peroba rosa, but Aspidosperma polyneuron Aspidosperma polyneuron (syn. Aspidosperma peroba Saldanha da Gama, Aspidosperma dugandii Standl., Aspidosperma polyneuron Müll.Arg. var. longifolium Hassl., Aspidosperma venosum Müll.Arg. also is Listed as contributing to the supplies. Some reference books simply say related species of Aspidosperma or refer to them as the "peroba group." The peroba group of Aspioderma species grows plentifully in Brazil, especially in the southeastern part of the country, and also is found in Argentina. A Colorful Species The wood, with its red to yellowish colored heartwood heartwood, the central, woody core of a tree, no longer serving for the conduction of water and dissolved minerals; heartwood is usually denser and darker in color than the outer sapwood. , is often streaked with purple and brown Purple and Brown is a claymation short on Nicktoons Network. The story is about two clay blobs, one purple and the other brown, friends who get caught in ridiculous situations. Despite any given predicament, the duo can never help but giggle with a low, recognizable laugh. , though it usually darkens to brown after exposure. The wood can yield beautiful figures, among them fiddleback and bird's-eye, and is often sliced into decorative veneer. Albert Constantine Jr., author of the book Know Your Woods, calls rosa peroba one of the highly important group of Brazilian timbers, comparable in general utility to the popular oak of the United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America. The United States is the world's third largest country in population and the fourth largest country in area. . "It is used in great abundance in all kinds of building construction," he wrote. Constantine Jr. describes the trees as large, with well-formed trunks, growing to heights as tall as 125 feet. "The trees are slender, with sparse foliage and a wrinkled bark, but they stand out in the landscape clearly because of their majestic appearance," he said. Myles Gilmer, owner of Gilmer Wood Products in Portland, OR, sells peroba rosa lumber, which he said is often named by color. "Various color types of peroba are given different names," he said, among them: peroba preta (rose red with black streaks); peroba muida (red with darker patches); peroba poca (almost white); peroba rajada (light pinkish red with Large black patches); peroba tremida (yellow with golden patches); and peroba revesa (with bird's-eye figuring, similar to bird's-eye maple bird's-eye maple n. A form of wood, chiefly of the sugar maple, that is patterned with small rounded figures and is especially popular for making musical instruments. Noun 1. ). "There is also peroba blanca and peroba nigra. Peroba rosa, which is a kind of pastel pink, is the most common of the peroba 'colors' used by the American market," Gilmer added. "It is also the most often [of this species] requested by my customers, who use it for a variety of applications, including kitchen cabinetry and casework case·work n. Social work devoted to the needs of individual clients or cases. case work , furniture accessories and specialty items Like
jewelry boxes. It is what I call a bargain-priced wood. There is a
little trick to kiln drying it, but once done successfully it offers few
problems when working with it. It is generally fine textured and takes a
nice polish."
Gilmer gets his supplies from southern Brazil. "It's a very inexpensive lumber. It is sliced into veneer, but I haven't seen much of that in the U.S. market," he said. Peroba Pal Peroba rosa should not be confused with peroba de campos from the species Paratecoma peroba, which is also a Brazilian hardwood, but from the Family Bignoniaceae Noun 1. family Bignoniaceae - trees or shrubs or woody vines or herbs having fruit resembling gourds or capsules; sometimes placed in the order Scrophulariales Bignoniaceae . Peroba de campos is sometimes called white peroba, which could Lead to confusion because, as noted previously, woods from the peroba group are often named by color. Other common names for peroba de campos include: ipe clare, ipe peroba, peroba amarelle am·a·relle n. A type of sour cherry having pale red fruit and colorless or nearly colorless juice. [German, from Medieval Latin am , peroba branca and golden peroba. Its weight ranges from 43 to 52 pounds per cubic foot, with an average weight of 47 pounds per cubic foot. Wood from peroba de campos is valued for its excellent durability and is used in civil and naval construction, decking, exterior construction and joinery, and for commercial flooring. Peroba de campos also can be sliced into veneer for use in cabinetry, paneling and marquetry marquetry (mär`kətrē), branch of cabinetwork in which a decorative surface of wood or other substance is glued to an object on a single plane. . The heartwood of peroba de campos varies in color from light olive-brown with yellow, to green or red tones and variegated variegated adjective Multifaceted; with many colors, aspects, features, etc stripes. Its grain is most often interlocked or wavy. Dust from the wood can be irritating and splinters are said to be poisonous.

Common Names Peroba rosa, rosa peroba, red peroba, palo, rosa, amarello, amargoso, ibira-romi, palo rosa Height/Weight The height ranges from 90 to 125 feet, with 4 to 5 foot diameters. Peroba's weight averages 47 pounds per cubic foot, with a specific gravity specific gravity, ratio of the weight of a given volume of a substance to the weight of an equal volume of some reference substance, or, equivalently, the ratio of the masses of equal volumes of the two substances. of 0.65. Properties Experts recommend care in drying to avoid problems. Suggested is a kiln schedule of T6-D2 for 4/4 stock and a schedule T3-D1 for 8/4 stock. Peroba rosa is said to season without much splitting, however distortion may be a problem. The presence of irregular grain may cause tearouts when planing, but the wood generally works well with hand and machine tools. The wood is classed as durable, it takes a finish well and can be glued satisfactorily. The wood is considered comparable to oak in strength properties. The sapwood sapwood, relatively thin, youngest, outer part of the woody stem of a tree, the part that conducts water and dissolved materials. In the cross section of a tree, the sapwood is recognizable by its texture and color; it is softer and lighter than the inner heartwood. and heartwood are not clearly demarcated and the wood has low to medium luster. There is no distinctive odor, but the wood is said to have a bitter taste. |
