Dammar

Dammar resin as incense

Dammar or dammar resin is the resin of deciduous trees from the wing fruit family that grow in India and on the Sunda Islands in the Malay Archipelago . Dammar is also produced in Indonesia , Papua New Guinea and the Philippines.

The most important source is the Shorea wiesneri tree , but the resin is also obtained from many other Shorea , Hopea and Vatica species as well as from Neobalanocarpus heimii .

The colors of the different varieties vary from clear-light, yellowish to black-gray Sumatran damar. The white dammar is the resin of the Indian species Vateria indica , black dammar comes from Canarium strictum from the family of the balsam tree plants . The so-called hard dammar, another name of the Kauri resin (New Zealand Dammar), is the resin of the New Zealand Kauri spruce ( araucaria family ), a conifer that is extracted from fossil deposits as a significantly harder copal .

The degree of hardness of the damar resin is similar to that of rosin , it is less hard and durable than Copal. The resin is slightly sticky and, when broken, is shell-like and shiny. The scent is fine lemon and light. When crushed, the result is a white powder with an aromatic, bitter taste.

The name Dammar comes from Malay and means tear, resin tear, resin or light, torch. Other names are Resina Dammar , Dammar Gummi, Cat's Eye Resin, Felsendammar, Steindammar and Salharz.
