There are skills in selecting boards: first look, then smell, and finally weigh.

　　There are many places where boards are needed in home decoration, so choosing the right boards is crucial during the renovation. When purchasing boards, you can indeed follow the technique of "look, smell, and weigh" to make a more informed choice. The following will explain in detail the meaning and specific methods of these three steps:

　　Look:

　　This step mainly involves observing the appearance and texture of the boards. First, check whether the surface of the board is flat and smooth, and whether there are any obvious defects, cracks, or scratches. Secondly, observe whether the texture of the board is natural and clear; good boards often have uniform textures that can showcase the natural beauty of the wood. Additionally, pay attention to whether the color of the board is uniform, and whether there are any color differences or fading. Through these observations, you can initially judge the quality of the board.

　　Smell:

　　This step is to judge the quality of the board through smell. High-quality boards usually have a natural wood fragrance that is fresh and subtle, without being pungent or uncomfortable. In contrast, if the board emits a strong odor, it may have used inferior glue or contain harmful substances, and such boards should be avoided. Therefore, when purchasing boards, it is advisable to get close to the board and smell it to discern its quality.

　　Weigh:

　　This step is to assess the weight and density of the board through touch. Generally speaking, for boards of the same volume, the heavier the weight, the higher the density, and the better the quality. This is because boards with high density often have better resistance to deformation and load-bearing capacity. When weighing the board, you can pick up one corner of the board with both hands, gently shake it or feel its weight. At the same time, you can also tap the surface of the board with your hand and listen to whether the sound it produces is crisp and pleasant, which is also a method to judge the density and quality of the board.

　　In summary, "look, smell, and weigh" is a simple and practical technique for purchasing boards. Through careful observation and feeling in these three steps, we can initially filter out high-quality boards that meet our needs. Of course, during the purchasing process, other factors such as Brand reputation, Price, and so on should also be considered comprehensively to make the best decision.
