Originally wax was something bees made the inside of their hives out of, that people harvested to use. Wax is soft enough to be able to mold it into new shapes, but doesn't melt at room temperature. Liquid wax will burn with a bright light, and is used to make candles out of. Things that are waxy and similar to beeswax are also called wax. Modern candles are made from paraffin wax. The stuff you sometimes scratch out of your ears is waxy and called earwax. Many cosmetics like lipstick are made mostly from wax.
