RESIN

From Agepedia

RESIN ; a vegetable substance, which exudes from many trees, either from natural fissures or artificial wounds. (See Plants.) Common resin, or rosin, is obtained by distilling the exuded matter of some species of pine: oil of turpentine passes over, and the resin remains behind. (See Pine.) The resins are insoluble in water, but soluble in alcohol, and inodorous, though they sometimes derive odor from containing an essential oil. They consist chiefly of carbon, with about one quarter of oxygen and hydrogen. (See Gum, and Gum Resin.)
