ad by Eric Meier When attempting to identify a wood sample, it's important to keep in mind the limitations and obstacles that are present in our task. Before starting, please have a look at The Truth Behind Wood Identification to approach the task in a proper mindset; I consider the linked article to be required reading for all those visiting my site with the intent of identifying wood. 1. Confirm it is actually solid wood. Before proceeding too much farther into the remaining steps, it's first necessary to confirm that the material in question is actually a solid piece of wood, and not a man-made composite or piece of plastic made to imitate wood. A solid piece of Cocobolo: note how the grain naturally wraps around the sides and endgrain of the wood. Can you see the end-grain? Manufactured wood such as MDF, OSB, and particleboard all have a distinct look that is—in nearly all cases—easily distinguishable from the endgrain of real wood. Look for growth rings—formed by the yearly growth of a tree—which will be a dead-giveaway that the wood sample in question is a solid, genuine chunk of wood taken from a tree. [...]
Jeffrey Pine (P. ponderosa pictured) Common Name(s): Jeffrey Pine Scientific Name: Pinus jeffreyi Distribution: Mountainous regions of southwestern Oregon to California and northern Mexico Tree Size: 100-165 ft (30-50 m) tall, 2-4 ft (.6-1.2 m) trunk diameter Average Dried Weight: 28 lbs/ft3 (450 kg/m3) Specific Gravity (Basic, 12% MC): .37, .45 Janka Hardness: 500 lbf (2,220 N) Modulus of Rupture: 9,300 lbf/in2 (64.1 MPa) Elastic Modulus: 1,240,000 lbf/in2 (8.55 GPa) Crushing Strength: 5,530 lbf/in2 (38.1 MPa) Shrinkage:Radial: 4.4%, Tangential: 6.7%, Volumetric: 9.9%, T/R Ratio: 1.5 Color/Appearance: Heartwood is reddish brown, sapwood is yellowish white. Grain/Texture: Straight grained with medium texture. Endgrain: Medium-large resin canals, numerous and evenly distributed, mostly solitary; earlywood to latewood transition fairly abrupt, color contrast can vary depending on growth ring spacing; tracheid diameter medium-large.

by Eric Meier (IWCS #9701)Are you interested in getting or using new and unusual wood species? Are you a wood collector? If so, maybe we can trade. If you are a member of the International Wood Collectors Society (IWCS), then you probably already know that the standard size for wood samples is 6" (long) x 3" (wide) x 1/2" (thick). What I've got for tradePlease note that this is not a for-sale list—I'm only looking to extend my diversity of wood species and therefore multiply the reach of the site. For purchasing wood samples, I'd direct you to other sources such as Gary Green, Carlton McLendon Inc, or the man who quite literally wrote the book on wood collecting, Alan Curtis. # Common Name Scientific Name Notes 001Pacific silver firAbies amabilisknot002Pacific silver firAbies amabilisapproximately 2.4" wide006Box elderAcer negundodefects007Red mapleAcer rubrumslight defects008Hard mapleAcer saccharum009Mountain mapleAcer spicatumglued up (two piece), defects010Ambrosia mapleAcer sp.011Ambrosia mapleAcer sp.streaked, but without bug holes012Yellow buckeyeAesculus flava (= A. octandra)191ChamfutaAfzelia quanzensis013KauriAgathis australisswamp-recovered Kauri015LebbeckAlbizia lebbeck158LebbeckAlbizia lebbeck2 7/8" wide016Black sirisAlbizia odoratissima017BoonareeAlectryon oleifoliusglued up (two piece), 7/16" thick, 5 3/4" long018BoonareeAlectryon oleifoliusmostly sapwood019BulokeAllocasuarina luehmanniiminor defects020BulokeAllocasuarina luehmanniidefects021BulokeAllocasuarina luehmannii022Red alderAlnus rubraknot one side259Emien Alstonia congensis2 7/8" [...]
