Color\/Appearance:<\/strong><\/a> Heartwood initially a pale pinkish brown, darkening with age to a more golden to medium\u00a0brown. Pale\u00a0yellowish sapwood is well defined. Can be highly figured, with grain patterns such as pommele being sought after in veneer form.<\/p><\/blockquote>

Grain\/Texture:<\/a><\/strong> Grain can be straight, interlocked, wavy, or anything in between. (Veneer sheets also exhibit a wide range of grain patterns.) Texture is medium to fine, with a good natural luster.<\/p><\/blockquote>

Rot Resistance:<\/a><\/strong> Heartwood ranges from moderately durable to very durable regarding decay\u00a0resistance. Bosse also has fair resistance against insect attacks and has good weathering\u00a0characteristics.<\/p><\/blockquote>

Workability:<\/strong><\/a> Results may vary depending upon the grain of the wood: interlocked and\/or quartersawn pieces can pose a difficulty planing, with tearout being common. Silica is present in this wood, causing cutting edges to blunt and dull at an increased rate. Glues, turns, and finishes well.<\/p><\/blockquote>

Odor:<\/a><\/strong> Bosse can have a distinct, cedar-like odor while being worked.<\/p><\/blockquote>

Allergies\/Toxicity:<\/strong><\/a> Although severe reactions are quite uncommon, bosse has been reported as a sensitizer<\/a>. Usually most common reactions simply include eye, nose, throat, and skin irritation, as well as a number of other effects, such as\u00a0asthma-like symptoms, nausea, and headaches.\u00a0See the articles Wood Allergies and Toxicity<\/a> and Wood Dust Safety<\/a> for more information.<\/p><\/blockquote>

Pricing\/Availability:<\/strong><\/a> Usually available as figured veneer. Prices for Bosse will depend greatly on grain patterning and intensity. Overall, expect prices to be very high for strongly figured pieces of quilted or pommele veneer, with curly figure or weaker patterns in the mid to upper price range for an imported veneer.<\/p><\/blockquote>

Sustainability:<\/strong><\/a>\u00a0This wood species is not listed in the CITES Appendices, but\u00a0is on the IUCN Red List. It is listed as\u00a0vulnerable due to a population reduction of over 20% in the past three generations, caused by a decline in its natural range.<\/p><\/blockquote>

Common Uses:<\/strong><\/span> Veneer, furniture, cabinetry, inlay, flooring, boatbuilding, and turned objects.<\/p><\/blockquote>

Comments:<\/strong><\/span> Bosse is one of a handful of commercial hardwoods in the Meliaceae family that can have a mahogany-like appearance<\/a>. Bosse veneer, in its multitudinous grain patterns, can bear a strong resemblance to sapele (Entandrophragma cylindricum)<\/em><\/a>\u2014another hardwood in the Meliaceae family with veneer that can exhibit very strongly figured grain patterns.<\/p>

The closely related Leplaea thompsonii<\/em> is sometimes mixed with L. cedrata<\/em> and sold interchangeably<\/span>\u00a0as bosse, though the former species tends to be slightly heavier and darker, and is sometimes called dark guarea to help distinguish<\/span> it from its lighter-colored ilk.<\/p><\/blockquote>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
