lumber often commands a higher price because the rays make a decorative figure in species like the oaks (white oak in particular), maple, sycamore and beech. Figure 14. This figure shows (A) a quartersawn board and (B) a flatsawn board. In quartersawn boards the rays are parallel to the wide dimension, and in flatsawn boards the rays run perpendicular to the broad surfaces. BOARDS CUT FROM A SINGLE LOG WILL DRY AT DIFFERENT RATES. The way that boards are cut will affect the drying rate. More ray ends are exposed on the wide faces of flatsawn boards than on the edges of quartersawn boards. As a result, quartersawn boards will dry more slowly than flatsawn boards. Quartersawn wood is also used for bourbon barrel staves because the rays act as channels for liquids; barrels assembled from quartersawn staves have the rays running around the barrel perimeter instead of from inside to outside, and this helps the barrels remain watertight. Rays are conductive pathways for moisture leaving the wood. Because rays act like small pipes, boards that have more ray ends exposed will dry faster. Flatsawn boards expose lots of ray ends on the wide surfaces, so they will dry more quickly than quartersawn boards where the ray ends are exposed only on the board edges.
