Common Names
Redheart, Chakte Kok
Scientific Name
Erythroxylum spp. and Simira spp.
Southern Mexico to southern Brazil and Paraguay
Aptly named, in some instances freshly surfaced Redheart can be a very bright, watermelon red—though color can vary in intensity and hue from board to board: anywhere from a light orange/pink, (similar to Pink Ivory), to a darker brownish red. In some cases, it can look quite similar to Bloodwood, though usually with a more visible and figured grain pattern. Redheart’s vibrant color quickly fades to a reddish brown in direct sunlight, though this color change can be slowed (but usually not stopped entirely) by using a finish with UV inhibitors, and keeping the wood away from strong lighting. Grain is usually straight or irregular, with a fine, even texture. Low to medium natural luster. Endgrain: Diffuse-porous; small to very small pores arranged predominantly in radial multiples of 2-5; growth rings indistinct; rays not visible without lens; parenchyma varies by species: sometimes rare or absent, or vasicentric and weakly aliform (winged).

Laboratory tests have shown Redheart to be moderately durable to attack by decay fungi.
Redheart has good working characteristics, and planes, machines, and sands well. Turns, glues, and finishes well, though a brown color shift is to be expected.
