A large number of people believe that teak darkens with age. This is indicated by the darkening of the color and the changes in its grain pattern. However, there are a few myths about this, one being that teak doesn't darken with age because it's not timber but rather a natural and renewable source. This article will address all these questions as well as answer them. We know that teak grows quickly. It reaches its height in only two to four years, which is usually at a growth rate of 1 cm per year. It then reaches maturity in 10 to 20 years. After this, the trees begin to grow slowly and lose their strength, reducing their height by 2 to 3 cm per year. In the woods or plantations, they are generally calculated back up to the date of cutting and not beyond. Under constant care, a teak tree can reach the age of 100 years, but it cannot be considered a tree with such commercial value after reaching this age. In other words, it is unlikely that there will be any trees left for harvest for at least another 60 years. So people have been wondering why teak's color darkens as it ages. The first reason is that the heartwood of the teak changes to red over time. This is only part of the reason. The other half is that the oil in the wood has been used. The oil in a teak tree can be extracted and made into various products, such as soap, insecticides, and medicinal ointments. This process is similar to the making of linseed oil from flaxseed. This extraction occurs over time and increases as it ages. All living things have a certain amount of oils in their body to keep them healthy, especially for their skin and organs to work properly. However, when the oil from a living thing is used up, it starts to deteriorate and eventually becomes unusable. For example, you can use butter for a year or two, but then the butter will begin to smell bad and become useless. This is how the oil in teak has declined and become unusable. The problem with this is that many people buy teak because it is dark and doesn't seem to change color with time. They think that teak is very durable and will last for many years. They also think that there is no need to seal their furniture because the wood does not change color with time. They could be wrong or right. Scientists have researched this and have found that teak can indeed keep its color after time. One of the research experiments was done by a group of professors at a university in Malaysia. The purpose of the experiment was to see how much oil was left in the wood of different-age teak trees. They took 5 different teak trees, 1-year-old, 2 years old, and so on up to 20 years. They also took 5 areas of the same tree, one being right underneath the trunk, one at the base of the trunk, and two at the top above 1m height (just a bit). They then measured how much oil was left in each part of these teak trees. Several things may have changed about teak wood composed of trees that were cut many years ago. But the main reason for this is that each part of a tree will keep its oil differently and at different speeds. One part may use up its oil in one year, while the other part in two decades. The result was that the top teak wood lost all its oil faster than the wood underneath. This means that teak wood changes color because of this loss of oil over time. This is why it is a myth that teak does not darken with age. Teak does change color because of the loss of oil over time. If you want to be more certain, it is good to know that the oil in teak is biodegradable and this means that the wood itself can break down over time. This will eventually recycle into new trees again. The paint on the furniture may not eventually be damaged, but the wood itself may rot and become unusable. Hence, it is important to clean and treat the teak from time to time. Teak can be expected to change color over time, so there is no need for concern about it not being durable enough. However, you need to keep cleaning this wood frequently. Teak has a natural ability to absorb oil, which is why it doesn't darken in sunlight or other sources of light that are not very strong. But this ability is also what causes it to deteriorate over time. The other thing to keep in mind is that over time the teak will lose its oil faster than it can regain it, so it is important to clean and treat the wood regularly. If you don't, the results of this will be damage or deterioration of your wood. Sometimes wood can be damaged through improper use, leaving a stain or stain by scratching. A simple treatment of cleaning and application of oil will restore your furniture to like-new condition again.
