The Han Dynasty (202 BC – 220 AD) Jizhupian dictionary of about 40 BC hints at candles being made of beeswax, while the Book of Jin (compiled in 648) covering the Jin Dynasty (265–420) makes a solid reference to the beeswax candle in regards to its use by the statesman Zhou Yi (d. 322).[6] An excavated earthenware bowl from the 4th century AD, located at the Luoyang Museum, has a hollowed socket where traces of wax were found.[6] Generally these Chinese candles were molded in paper tubes, using rolled rice paper for the wick, and wax from an indigenous insect that was combined with seeds. By the 18th century, novelty Chinese candles had weights built into the sides of candles - as the candle melted, the weights fell off and made a noise as they landed in a bowl.
