DAMMAR, or DAMMER (See also:Hind. damar=See also:resin, See also:pitch)  , a See also:resin, or rather See also:series of resins, obtained from various coniferous trees of the genus Dammara (Agathis) . See also:East See also:Indian See also:dammar or See also:cat's See also:eye resin is the produce of Dammara orientalis, which grows in See also:Java, See also:Sumatra, See also:Borneo and other eastern islands and some-times attains a height of 8o–See also:loo ft . It oozes in large quantities from the See also:tree in a soft viscous See also:state, with a highly aromatic odour, which, however, it loses as it hardens by exposure . The resin is much esteemed in See also:oriental communities for See also:incense-burning . Dammar is imported into See also:England by way of See also:Singapore; and as found in See also:British markets it is a hard, transparent, brittle, See also:straw-coloured resin, destitute of odour . It is readily soluble in See also:ether, benzol and See also:chloroform, and with oil of See also:turpentine it forms a See also:fine transparent See also:varnish which dries clear, smooth and hard . The allied kauri See also:gum, or dammar of New See also:Zealand (Australian dammar), is produced by Dammara australis, or kauri-See also:pine, the See also:wood of which is used for wood paving . Much of the New Zealand resin is found fossil in circumstances analogous to the conditions under which the fossil See also:copal of See also:Zanzibar is obtained . Dammar is besides a generic Indian name for various other resins, which, however, are little known in western See also:commerce . Of these the See also:principal are See also:black dammar (the Hindustani kala-damar), yielded by Canarium strictum, and See also:white dammar, Indian copal, or piney varnish (sufed-damar), the produce of Vateria indica . Sal dammar (damar) is obtained from Shorearobusta; Hopea micrantha is the source of See also:rock dammar (the See also:Malay dammer-See also:batu) ; and other See also:species yield resins which are similarly named and differ little in See also:physical properties .
