Given that the breadth of ring diminishes, this latewood is lessened to make sure that incredibly slow advancement provides comparatively mild, porous wood made up of slender-walled vessels and wood parenchyma. In superior oak, these substantial vessels in the earlywood occupy from six to ten p.c of the amount on the log, though in inferior materials they may make up 25% or more.
