When it comes to the choice of oak color, many people choose according to their favorite color, that red oak is red oak, white oak is white oak, in fact, this is not the case, oak is not only the difference in color, how to choose oak ? Mido Furniture Xiaobian tells you.
Red Oak is widely distributed in various regions of the eastern United States. Oak is among the tree species in the eastern hardwood forests, with the highest number of trees, of which about eight are commercial trees. The appearance of red oak is usually similar to that of white oak, but due to the finer ray of the pith, the figure is less visible. The red oak is mostly straight grain and has a rough texture. It has its name due to red leaves in autumn, and its processing performance is good. , Dyeing and polishing can get a good surface, but it is slow drying and easy to crack and warp, high shrinkage, easy to change performance. Red oak is hard and heavy, with medium bending strength and rigidity, high breaking strength and excellent resistance to steam bending. The southern red oak grows faster than the northern red oak, and the wood is harder and heavier. The heartwood was rated as having little anti-corrosion ability and the preservative treatment was of moderate difficulty.
Second, look at the wood section <br> Under the magnifying glass to observe the annual ring of red oak, you can find very many cell holes, and the interior is empty, it should be easy to identify. White oak tubes have impregnated bodies. Although they are very subtle, white oak has excellent anti-corrosion and anti-insect properties. Water resistance is also better, so it can become a world-famous oak barrel material, while red oak can not Make wine barrels.
Third, look at the pith rays <br> Red oak pith rays are usually shorter, mostly 1/8''~1/2'' in length, and less than 3/4''~1'' in length. White oak's pith rays are longer than red oaks, and most of them exceed 3/4''.
Fourth, look at the leaves <br> This is the most practical and the easiest method, as long as the comparison of the shape of the leaves can distinguish red oak and white oak. The edge of the red oak leaves is sharp, while the white oak leaves are rounded.
Five, nitrite (NaNO2) test <br> This method is very accurate and reliable, although a bit overkill, but when the physical method does not work, you can still use this method. Note: Nitrite can only make color changes in the heartwood. First, we need to prepare the heartwood of red oak and white oak, and then use a 10% nitrite solution (1% to 20% sodium nitrite solution can successfully complete the experiment. Here we recommend the best concentration 10%). If Red Oak's heartwood is coated with a nitrite solution, the color does not change much over time, meaning that it is slightly darker and sometimes slightly greenish. However, if it is the heartwood of white oak, the color will change obviously. The color will change from the original color to the color of the sauce, and then it will gradually turn into a deep blue color, and it will eventually become almost black.
