Copal 

a class of natural fossil resins composed primarily of resin acids. Copals are extremely hard, with a high melting point (up to 360°C and higher) and great chemical stability. Their density is 1.03–1.07 g/cm3. The color of copals ranges from colorless to brown. The names of copals are often derived from the places of extraction, for example, Zanzibar, Mozambique, Angola, Borneo, and Brazil copals. Copals are widely used in the manufacture of varnishes. With the appearance of synthetic resins, their importance has decreased.
