Paraffin wax was introduced to candle making during the 19th century. Like beeswax candles, paraffin candles burned without the smoky flame associated with tallow candles. Paraffin candles were also odorless when burned. Introduction of paraffin was considered as a boon to the candle industry as it resulted in a superior and less expensive candle. The boon was short-lived as the candle industry began to decline with the introduction of the electric light bulb in the late 19th century.
