Understanding Wood Sapwood, Heartwood and Circle Year

Do you know what is sapwood? And what is wood patio? And what is the circle? These terms are very often we hear when we talk about things related to wood, especially wood logs or log still form. In short, the notion of sapwood, wood porch and circle year are as follows:

  • Sapwood is the edge or the edge of the wood.
  • The heartwood is the center or core of wood
  • Circle of the year is a sign that indicates the age of a tree or a call it rings on the wood because basically it can only be seen when the trees have been cut down or shaped timber.

Part of The Most Durable Wood

If you have questions, what part on the wood of the most durable and powerful? I instinctively would answer: patio section. You know why? Because part of the terrace on the wood part is known as having a level of durability is much better than in the sapwood (read what the wood porch and sapwood). This is evident in a wide variety of products made ​​from wood that is around us like furniture products, which certainly is a first porous or decayed sapwood section.

Why wooden patio more durable than the sapwood?


But because of the content of chemical elements (toxic substances), which makes it more durable part of the terrace on the other pig is because part of the terrace has a pore that is more dense than the rest of the sapwood. Pore ​​density makes the terrace becomes harder part that is not easily attacked by termites.

Drought level of Wood Determining of Furniture Quality

Quality wood furniture is determined by the level of moisture contained in the wood used. The more the wood is dry, then the resulting furniture will be more qualified. Therefore, wood moisture content is too high can lead to changes in the form of goods when it is created.

The changes are usually curved, shrink or even crack and break. For example, in the rainy season, maybe you have had your house door being difficult to open and close, or sounds. That's because the door shrinkage (slightly curved) so that the door had been fitted with sills and floor, when the rainy season comes so no flashlight (not fitted) again with the floor and the door frame, the door creaked and finished hard-lid open. Or another example of big chunks of furniture such as the dining table.That you also may have experienced as well. Table that was straight and flat gradually become curved so that the pair of glass on it to shake (not fit anymore). This means that the wood on the table to change the form of the curve. And it is definitely a timber that is used when making both items still have a high moisture content or still too wet. That's just an example of the two types of furniture are classified as indoor furniture (inside the house), what if the wet wood used for outdoor furniture directly related to weather such as heat and rain?
