What is Agarwood?
Agarwood is formed when the agarwood tree sustains an injury, allowing fungi to infect the wound. In response, the tree releases a range of defense substances, including phytoncides, to fend off the fungal invasion.
Through the intricate interaction between the fungi and the tree's secretions, a new substance known as "agarwood resin" is produced, serving as the precursor to agarwood. Over an extended period of transformation, this concentrated resin undergoes further maturation, ultimately becoming agarwood.
Throughout this lengthy process, influenced by unpredictable weather patterns, varied geographical conditions, and diverse resin-producing environments, the art of crafting agarwood incense becomes imbued with countless unknowns and possibilities. Each agarwood specimen, displaying distinct characteristics, is a testament to the profound influence of time and its mysterious brewing.
Classification of Agarwood
Due to the ever-changing and complex production environment of agarwood, there are various criteria and logics for its classification based on factors such as place of origin, production, harvest, and shape.
The most common classification method is to classify according to the state of submersion. Although they are collectively referred to as "agarwood", not all agarwood can sink in water. Agarwood that can completely submerge in water means that it has a high oil content, and the oil content exceeds a quarter of the weight of the whole piece of agarwood.
Those that sink completely into the bottom of the water are called "Shenshuixiang", and those that float on the water surface are called "Huangshuxiang". The greater its weight, the more it signifies rarity.
