Color and Grain

Santos Mahogany comes with several color variations between its boards. Sometimes it may take a lighter golden-brown color; sometimes, it takes a burgundy to a darker purplish color. Over time, its color shifts to a more reddish or purplish color. Its quartersawn sections exhibit ribbon or striped patterns. 

Its range of colors usually depends on where it is grown. Nevertheless, most lumber has dark orange/brown to medium orange/brown hue. Upon exposure to UV rays, its color gets slightly muted. Its interlocking grains also provide striped looks, though not all lumber has this heavy striping.

Santos Mahogany has a diffuse-porous feature with a few large pores with no specific arrangement, coming in two to three radial multiples. It also has indistinct growth rings, which appear distinct sometimes due to its discontinuous marginal parenchyma bands. It also has narrow rays that you can only see using a lens. These rays come in reasonably close spacing, confluent and vasicentric. 


Its density is very high at around 60 pounds per cubic foot. Its specific gravity is .74 at 12% MC. Sometimes, it is even heavier than water, making it sinks in water. A board foot of this wood (planed) usually weighs around 4-3/4 pounds. Thus, it is heavier than many hardwoods. 


Santos Mahogany is usually sawmill dried rather than shipped green. It is easy to dry and exhibits only minimal shrinkage during the drying process. It shrinks around 4.6% tangentially and 2.8% radially (flatsawn). Thus, this percentage of shrinkage is very low.
