Sinking vs. Non-Sinking Agarwood Chips: Is Heavier Always Better?
๐๏ธ Appraiser’s Note: As a Master Agarwood Appraiser based in Tu Son, Vietnam, I frequently receive questions about the sinking properties of agarwood. Let’s bypass the marketing myths and look at the physical facts.
The Verdict: Density Does Not Guarantee Quality
Heavier is not always superior. While sinking chips imply high resin saturation, the market is flooded with pressure-injected “heavy” wood that lacks the complex terpene profile of premium floating chips. True quality is determined by the Kinam-Note Saturation Index (KNSI). Do not mistake artificial weight, often achieved through chemical fillers or vacuum-loading, for the genuine, porous resin formation found in authentic wild-harvested Aquilaria Crassna.
Thermal & Physical Analysis: The Tu Son Approach
In our Tu Son laboratory, we analyze chips by how they release volatile organic compounds (VOCs) under controlled thermal application. Genuine high-grade chips exhibit a “layered olfactory expansion”—the scent evolves from top notes to a deep, earthy base. Conversely, fake or commercial-grade chips, even those that sink, often possess a singular, cloying, or synthetic chemical aroma that does not change during heating. When heated, authentic wood exhibits a clean, light-colored smoke, whereas chemically treated wood often produces acrid, thick, black smoke indicative of added resins or artificial oils. We prioritize the KNSI standard because it evaluates the crystalline structure of the resin rather than simple gravitational displacement, ensuring the oil content is biologically integrated rather than artificially forced into the wood fibers.
| Appraisal Feature | Authentic OudwoodVietnam (KNSI) | Fake / Commercial Grade (Chemical) |
|---|---|---|
| Scent Evolution | Complex, multi-layered, evolving notes. | Linear, synthetic, or cloying scent. |
| Smoke Quality | Clean, ethereal, non-irritating vapor. | Acrid, heavy, and irritating smoke. |
| Physical Appearance | Natural fiber patterns with resin veins. | Uniformly dark, oily, or artificial pores. |
The Ultimate Solution: Trust the KNSI Standard
To avoid synthetic traps and ensure you are getting genuine investment-grade Aquilaria Crassna, you must rely on strict appraisal matrices. Read our complete 2026 Master Guide to the KNSI Standard to verify authenticity and protect your health and investment.
