Amber is not mineralized. Its chemical composition varies, with regular H2S inclusions. Amber melts easily in the flame of a candle emitting a characteristic smell, and is soluble in 20 to 25% alcohol, 18 to 23% ether, or 9.8% benzene. Wash with soap and water. Amber is a fossilized resin from ancient coniferous trees which grew near the Baltic during the Tertiary era; it is found as irregular nodules in a marine glauconitic sand - "blue earth" -. Eroded amber layers were transported later on by glaciers, rivers and the sea towards the West, North Germany and Denmark, where they could be collected on the coast.
