Wood Trading

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" [...]

Wood Allergies and Toxicity

by Eric Meier "Not to omit any one of them, the yew is similar to these other trees in general appearance . . . It is an ascertained fact that travellers' vessels, made in Gaul of this wood, for the purpose of holding wine, have caused the death of those who used them." –Pliny the Elder, from Naturalis Historia, ca. 77 AD Looking at the above quotation, (taken from a writing nearly two thousand years old), ought to bring—at the very least—a small bit of respect and attention to the matter of safety as it pertains to wood toxicity. If this subject has been known and reported as "ascertained fact" since ancient history, how much more ought we to take heed in modern times, considering that we have so many more well-developed means of communication and testing? Wood Toxicity and Allergen Chart Below you'll find a chart of various wood species, along with their reported effects and properties. The information on this chart has been compiled from many sources, with references given at the bottom. When viewing the chart, please keep the follow in mind: Just because any given wood is not listed on the chart, does not mean that [...]

What is Wood?

by Eric Meier Hardwoods and Softwoods Tree Growth Sapwood and Heartwood Surfaces of Wood Grain Appearance Rays It’s common knowledge that wood comes from trees. What may not be so apparent is the structure of the wood itself, and the individual components that make up any given piece of lumber. Unlike a mostly homogenous piece of foamboard, MDF, or other man-made material, wood is an organic material, and has many distinct characteristics which will be helpful to learn. Hardwoods and Softwoods An immediate and broad distinction that can be made between types of trees (and wood) is the label of hardwood or softwood. This is somewhat of a misnomer, as the label is actually just a separation between angiosperms (flowering plants such as maple, oak, or rosewood), and conifers (cone-bearing trees such as pine, spruce, or fir). Hardwoods (angiosperms) have broad-leaved foliage, and tend to be deciduous—that is, they lose their leaves in the autumn. (However, many tropical hardwood species exist which are evergreen—they maintain their leaves year-round.) Additionally, hardwood trees tend to have a branched or divided trunk, referred to as a dendritic form. This White Oak tree—with a branching form, and leaves that drop in the autumn—is [...]


> Hardwoods > Fabaceae > Acacia Example species (Acacia melanoxylon) Common Name(s): Acacia, wattleDistribution: Primarily Australia; a few species are found in Asia and the Pacific islandsGenus Size: Nearly 1,000 species (see available species listing)Mechanical Characteristics: Density greatly variable, some species can be very heavy and hard, though most commercial species are of moderate weight. Visual Characteristics: Many species have a medium to dark brown heartwood with sharply demarcated sapwood. Figured grain patterns such as curl (commonly called "ringed" in Australia) are also seen.Identification: Wood is diffuse porous (not ring-porous), typically with medium to large pores. Parenchyma tends to be primarily vasicentric and isn't generally seen with extensive and wide bands. Many species of Acacia will fluoresce under a black light, which can help to separate them from other lookalike genera. Comments: Acacia is a very large and diverse genus, containing several hundred species, ranging from woods weighing less than black cherry (Prunus serotina)—such as mangium (Acacia mangium)—to some of the heaviest and hardest woods on earth—such as waddywood (Acacia peuce). Because of this great diversity within the genus, it is nearly impossible to typify a standard wood that is representative [...]

Common US Hardwoods

by Eric Meier In the process of identifying wood, things can get a bit overwhelming when faced with the hundreds and hundreds of possible species. Yet in the context of everyday woods that most people in the United States or Canada are likely to encounter, the list of possible woods is usually much shorter. This article is meant to act as sort of a "Cliffs Notes" to help address the most common (and hopefully, obvious) questions of wood identification. Red Oak (Quercus rubra) 1. Oak Comments: This wood is everywhere! Chances are, there's something made of this wood within a stone's throw of where you're sitting right now. It's used for cabinets, furniture, flooring, trim, doors, and just about anything else that can be made of wood! It's very frequently stained a medium reddish brown, so it may look slightly darker than the raw sample pictured to the left. Lookalikes: Ash (lacks the prominent rays that are found in oak). Also, see the article on Distinguishing Red Oak from White Oak. Hard Maple (Acer saccharum) 2. Maple Comments: This light-colored wood is seen almost as frequently as oak, and is usually not stained a dark color, but is kept a natural [...]

Restricted and Endangered Wood Species

by Eric MeierThe issue and ethics surrounding the utilization of trees for lumber is oftentimes both expansive and ambiguous. Not only are there questions of sustainability (i.e., given the current rate of harvesting, can a particular species continue to reproduce at a sustainable rate so that demand will not outstrip supply?), but there's also the matter of habitat destruction (i.e., even if a tree species can be sustainably harvested from the wild, would doing so destroy or endanger other species in the same habitat?).Further mixed into this murky cocktail is the fact that for some countries—especially poorer third-world countries—lumber is big business, and placing a restriction on such a lucrative sector of their commerce would be seen as counter-productive, and consequently actual or potential levels of exploitation may not be easily or readily discovered.However, despite the complexity of the issue, and the incomplete or even possibly faulty data, some information is better than no information. With these shortcomings in mind, there are two international entities that will be used and cited on this website, CITES and the IUCN.CITESAn international agreement between governments was formed in 1973, called the Convention on International Trade of Endangered Species, or CITES for short. CITES has three different levels of protection [...]
