08. Wood = Lumber = Timber / features of wood

Last time, it was a time to learn about a little industrial and cold looking metal, aluminum.

On the contrary, today I am going to introduce you to Wood, which gives a warm feeling!

If you look around closely, you will often see things made of wood.

The wardrobe and mini-ladder I bought from IKEA right now, and the handle

that connects the upper floors are the most noticeable.

 

Ah! There was also a desk that allowed me to sit down and blog!

You can see it all around us like this.

In addition to houses, most of them are made of wood in traditional tea houses,

jjimjilbang(korean spa space), and traditional villages.

Also, like the Casamia showroom, you can see a furniture and accessories showroom,

and a clean and living cafe made of wood.

I think wood is a material that can realize everything from a traditional feel to a living feel.

 

Then, shall we go to find out about wood that boasts a variety of atmospheres?

Wood refers to any material made of wood.

It is said that wood can be obtained mainly from plants with tree trunks.

The tree trunk, also referred to as Mokbonkyung here, means a wooden trunk,

and it is a thick part that allows leaves to grow by making branches from tree posts.

There are many other parts of wood used,

but it is said to be mainly used for bestiality unless there is a special case.

There are two types of wood: coniferous and hardwood.

Conifers are plants that produce bell fruit and have sharp leaves.

On the contrary, broad-leaved trees are also called broad-leaved trees and have flat leaves.

The constituents contained in conifers and hardwoods differ slightly.

The main ingredients are cellulose, hemicellulose, and lignin.

Next, we will briefly introduce the history of wood!

The first wood was discovered in 2011 in New Brunswick, Canada.

This wood, measured by carbon dating, is estimated to be about 395 million to 400 million years old. The full name'radiation carbon dating method' is a method of estimating the age

by measuring the composition ratio of radioactive isotopes of carbon.

Our humanity has long used wood for numerous purposes, including building materials,

furniture, supplies, and lighting.

 

It was also used for weapons and tools.

Next, we will look at the properties of wood.

 

First of all, the nature of wood seems to be a disadvantage, but wood is very, very weak to moisture. Depending on the amount of moisture the wood contains, it often causes shrinkage and expansion. Durability is divided into good and bad depending on the decay, insects, and insects of the wood.

In addition, wood can be divided into heartwood and sapwood.

The core material is a dark core part that is visible when a section of wood is cut horizontally,

and it is mainly used as a building material

because it is strong against corrosion and has little resistance.

 

However, as mentioned earlier, it is weak to moisture,

so it is worth considering that it is used as a building material in places with a lot of external moisture. On the other hand, sapwood with fewer nodes is used for finishing.

 

 

 

 

Lastly, I'll simply point out the use of wood and finish it.

 

 

Like this, it can be used for instruments such as piano

 

It can be applied to building materials or interior interiors,

It can also be used for furniture such as beds.

Also, you may have seen it at least once while passing the railroad,

and it can be used as a sleeper to support the underside of the train rail.

In addition to these uses, wood is used in a huge number of places

Wood, which is fragile, but hard and warm, seems to be the nature

that mankind was able to get help for the first time.

I would have made fire with stone and brought wood to keep the fire,

so would be stone and earth.

 

In fact, I think that my house gives a feeling of relief and stability without knowing,

but I think I felt the cozy feeling because there are quite a few products made of wood :)

The wood was relatively short compared to the other series,

but I think it helped! See you next time with more useful materials :)

 

Nice work today!
