Methods for identifying wood
It mainly includes two methods: macro identification and micro identification.
Macro identification
Macro recognition is the process of identifying wood by observing its appearance features with the naked eye or using a magnifying glass. This method is widely used in production practice, but its accuracy is relatively low. The steps for macro identification are as follows:
Observing texture and color: Different woods have their own unique textures and colors, such as the clear and straight texture of rosewood, with varying shades of color; And Ke Tan has an orange red color and denser annual ring patterns.
Check black veins: Red acid branches have more and more obvious black veins, while light colored red acid branches have fewer black veins.
Smell: Some woods have a unique odor, such as agarwood, which secretes resin with a strong aroma after being damaged or infected by fungi.
Microscopic identification
Microscopic identification is the process of observing the microscopic anatomical features of wood under an optical microscope or electron microscope for identification. This method has high accuracy, but is complex to operate and is usually used in research institutes and authoritative appraisal institutions. The steps of microscopic identification are as follows:
Slicing: Cut the wood into thin slices and observe the morphology and arrangement of its cells and tissues. 1
Comparison specimen: Compare the observed features with correctly named wood specimens and sections to ensure accuracy in identification.
Identification tools and standards
When conducting wood identification, it is necessary to use properly named wood specimens and sections, which should come from the specimen rooms of research institutes and universities, and be accompanied by Latin scientific names. In addition, auxiliary tools such as magnifying glasses, optical microscopes, and pairwise search tables are also required.
By combining macro and micro methods, the type and quality of wood can be more accurately identified.
