Cách sử dụng
Sapwood is the outer layer of wood in a tree trunk or branch that is alive and transports water and nutrients up from the roots. It is usually lighter in color than the inner layer of wood called heartwood. Sapwood is important in woodworking because it is more susceptible to decay and insect damage than heartwood. When choosing wood for a project, it is important to consider the amount of sapwood present because it may affect the durability and strength of the wood.
