Description.
Damar batu or damar gum or damar stone is a unique natural resin found in some parts of Indonesia.
Damar batu is a hardened form of resin produced by certain tropical trees, particularly from the Shorea species. Over time, the resin crystallizes into solid chunks, giving it a stone-like appearance.
Unlike fresh damar (which is sticky and soft), damar batu is dry, brittle, and often translucent with a yellowish to brown color.
Damar batu is primarily found in forest regions of Sumatera, especially in areas like West Sumatera, Lampung, South Sumatera and Riau. These regions are rich in tropical rainforests where damar-producing trees grow naturally.
