When evaluating charcoal briquettes, specifications like "ash" and "moisture" are commonly discussed. However, for a truly deep understanding of quality, sophisticated buyers must look at two key scientific metrics: Fixed Carbon and Volatile Matter. These two components, more than anything else, determine the actual performance and efficiency of the fuel.
What is Fixed Carbon? Fixed Carbon is the pure, solid carbon component of the charcoal. This is the real fuel. It's the substance that glows red and produces the steady, radiant heat you need for cooking or shisha.
The Higher, The Better: A higher percentage of Fixed Carbon means there is more pure fuel in every briquette. This directly translates to:
Higher Calorific Value: The briquette produces more heat energy.
Longer Burn Time: With more fuel to consume, the briquette lasts significantly longer.
Our Standard: Premium coconut charcoal briquettes from a quality manufacturer should have a Fixed Carbon content of 80% or higher.
What is Volatile Matter? Volatile Matter refers to the other substances trapped in the charcoal (like tar, gases, and other impurities) that are released as smoke and flame when heated.
The Lower, The Better: A high percentage of Volatile Matter is a sign of incomplete or poor carbonization. It leads to:
Excessive Smoke and Flames: This is the initial, often unpleasant smoke you see when lighting low-quality charcoal. These flames can burn food on the outside before it's cooked on the inside.
Unpleasant Odors and Taste: The impurities released can impart a bitter, "off" flavor to food.
Wasted Energy: Energy is wasted producing flames and smoke instead of the desired steady, glowing heat.
Our Standard: A top-tier briquette should have a Volatile Matter content of below 15%.
The Relationship: A Perfect Balance The goal of a professional charcoal manufacturer is to maximize the Fixed Carbon while minimizing the Volatile Matter. This is achieved through a precise, controlled carbonization process that bakes off the impurities without burning away the pure carbon.
Conclusion for Importers When you request a Technical Data Sheet (TDS) from a supplier, don't just glance at it. Look specifically for the Fixed Carbon and Volatile Matter percentages. A supplier who can confidently provide and guarantee these numbers is a supplier who has mastered the science of charcoal production. This is your best indicator of a truly premium, high-performance product.
