Natural amber reacts very weakly with diethyl ether and various solvents. The imitation of Coba resin reacts with diethyl ether and acetone (nail polish to remove water). In a very short time, the surface will become dull and sticky. Coba resin has a strong fragrance. When the coke resin is contacted with a hot needle, it melts and sticks to the needle to form a long "line". Products made from Coba resin are exposed to sunlight and air and produce very small, deep hair-like cracks.
