It's Not the Wick That Burns – How Scented Candles Are Made

Light a scented candle and the flame isn't really burning the wick – it's burning wax vapor. In this episode we take apart the humble scented candle: from Egyptian rushlights, Roman tallow and whale-oil "standard candles", to modern paraffin and soy wax, fragrance oils, wicks, pouring, curing and burn testing. We also look at candles in faith (Easter candles, the Hanukkah menorah, Diwali lamps) and where birthday candles come from. Plus: why a flame is shaped like a teardrop (and round in space), how hot it really gets, why smells trigger memories, and how to make your candle last longer.
