In the world of agarwood connoisseurship, the term “Sinking Agarwood” is often hailed as the ultimate pinnacle of luxury. A typical piece of Aquilaria wood is porous and buoyant; only when resin accumulation over centuries exceeds 25%–30% of its volume—pushing its density beyond 1g/cm³—does the wood naturally sink. Such authentic, naturally sunken agarwood is so rare that its price can reach astronomical heights.
Exploiting the desire for these “rare sinking treasures” among well-meaning but uninformed buyers, unscrupulous vendors have created incense sticks labeled as “100% Sinking Agarwood” through malicious means: injecting lead powder, mercury solutions, and industrial adhesives into the wood core. At Phu Van Huong, we believe it is time to expose this dangerous deception.
The ‘Lead-Casting’ Technology: Turning Incense into Heavy Metal Vaporizers
To force a stick to sink in water for a sales demonstration, criminals mix lead (Pb) powder or mercury (Hg) salts into sawdust and industrial glue before extrusion. When ignited, these heavy metals sublimate at high temperatures, releasing microscopic toxic oxide vapors into your home. Inhaling this smoke can lead to bone marrow toxicity, neurological damage, chronic kidney failure, and incurable cancers.
The True Essence of Premium Agarwood Incense
True connoisseurs understand that the value of an incense stick lies in the purity of the smoke and the olfactory profile, not in whether it sinks in water:
- Our coreless incense sticks are crafted from finely ground natural agarwood and wild mountain Litsea glutinosa bark binder. Even when using oil-rich Antique Wild Agarwood (Tram Ruc), the extrusion process (2.2mm–2.5mm) maintains a micro-porous structure. This allows the stick to burn steadily without the need for chemical accelerants or synthetic ash-curling agents.
- Authentic, natural incense will float or hover in water, leaving the liquid clear and emitting a subtle, woody aroma. Any claim that a stick must sink like a stone is a hallmark of heavy metal adulteration.
