FAQ

Frequently Asked Questions

No. Animal charcoal (bone char) is a specific type. Activated charcoal is a broader category of processed carbon with high porosity, often from sources like coconut shells or wood.

Its use is now very limited and mostly historical or niche. It has been largely replaced by more efficient and consistent activated carbons.

To distinguish it from charcoal made from wood or other plant materials, as its source was specifically the bones of animals.

Its primary historical use was in the sugar industry to adsorb colored impurities and decolorize raw sugar syrup, producing white sugar.

A porous, carbon-rich substance obtained by charring animal bones, used primarily as a filtering or decolorizing agent.
