Given that the breadth of ring diminishes, this latewood is minimized making sure that very gradual expansion generates comparatively light, porous wood composed of skinny-walled vessels and wood parenchyma. In good oak, these substantial vessels on the earlywood occupy from six to ten p.c of the volume in the log, whilst in inferior substance They could make up twenty five% or more.
