Bloodwood

Bloodwood is the trade name for the wood of Brosimum rubescens, a tropical hardwood tree of the Amazon basin and the Guianas in northern South America. It belongs to the fig and mulberry family (Moraceae) and is closely related to the woods sold as "satine," a name it shares. The species is best known for one thing above all: its saturated, vivid red heartwood, among the most intensely colored of any timber in the trade.

The tree is a medium-to-large rainforest hardwood, and the harvested heartwood is exceptionally dense and hard. The sample shown is characteristic of a weathered board: a reddish-brown surface with darker aging stains and straight grain, the deeper red revealed when the oxidized outer face is cut or sanded back. Freshly worked, the wood is a bright crimson to blood-red that mellows and darkens with age and light exposure.

The heartwood is a bright, vivid red to deep blood-red or crimson when freshly cut, sometimes with darker red or brown streaking, and it darkens over time toward a muted reddish-brown or brownish-red, especially with UV exposure. The narrow sapwood is a pale yellowish to whitish tone and is sharply demarcated from the colored heartwood. Grain is typically straight — matching the sample — though it can be interlocked or wavy, and the texture is fine and even with a good natural luster.

Bloodwood is a genuinely heavy, dense wood, averaging roughly 66 lb/ft³ (about 1,050 kg/m³) dried, well above most domestic hardwoods, and it rates around 2,900 lbf on the Janka scale — firmly in the very hard range. The heartwood is durable and rated resistant to decay, though it is reported to be susceptible to insect and borer attack, so it is not a first choice for ground contact. Its high density also makes it slow to dry and prone to checking if seasoned too quickly.

Bloodwood's color, density, and fine texture make it a favorite for small, high-value work where the red is wanted as a feature. It is widely used in turning — bowls, pens, boxes, spindles, and knife and tool handles — and in inlay, marquetry, and accent banding, as well as for guitar and other instrument components and trim.

Where board sizes and budget allow, it also appears in fine furniture accents, cabinetry highlights, carvings, and small specialty items. Its hardness and wear resistance suit it to items that take handling, and its striking color means it is most often used as a contrasting element rather than for large expanses. It has historically been used as a source of red dye as well.

Bloodwood is hard, heavy, and can be demanding to work. Its density blunts cutting edges and its interlocked or wavy patches can tear out, so sharp tooling and light cuts give the best results; it is also prone to splitting, so pre-boring for nails and screws is advisable. On the plus side it turns cleanly, takes a very smooth surface straight off the tool, and polishes to a high natural luster with fine texture.

Gluing can occasionally be affected by the wood's density and natural oils, so clean, freshly machined surfaces help; it finishes well and its color can be protected somewhat with a UV-inhibiting finish, though some darkening over time is unavoidable. Note that the red pigment can bleed into adjacent light-colored woods and into finishes, so care is needed in glue-ups.

Caution: bloodwood dust is reported to be an irritant. Fine dust can irritate the eyes, skin, and respiratory tract, and reactions such as nausea, headaches, and general respiratory irritation have been reported by some workers; the pigment also stains skin and clothing. Use dust extraction and a respirator when machining and sanding. Brosimum rubescens is not listed on any CITES appendix and is not currently flagged as internationally threatened.

Bloodwood is a moderately available exotic hardwood, imported to North America and Europe mainly as turning blanks, craft stock, small boards, and lumber in modest widths. Because the trees do not commonly yield very wide, clear, defect-free boards, large or figured pieces command a premium, while turning and small-project stock is more accessible.

Price sits in the moderate tier for an exotic hardwood — more than common utility imports but generally below the true rosewoods and other restricted species. On sustainability, Brosimum rubescens is not CITES-listed and is not on the IUCN threatened list at species level, so it moves in trade relatively freely; as with all tropical timber, responsibly sourced or FSC-certified stock is the better choice given ongoing pressure on Amazonian forests. Buyers should confirm species, since "satine" is a name shared with related Brosimum woods.
