Beeswax is made during the summer months by worker bees. When the workers are about 10 days old they eat lots of honey which is converted into wax. The wax then seeps through pores on on the bees' tummies. The bees use the wax to make the honeycombe and to cap the honey. When the honey is extracted, the wax is melted down, filtered and then poured into candle moulds, to make wonderful natural candles.
As well as being a good use of a byproduct of the British honey industry (which sorely needs our help), beeswax candles are also better for the enviroment than paraffin wax candles. The most comprehensive study of the air pollution caused by burning paraffin candles was prepared in 2001 by the US Environment Protection Agency. It concluded that when paraffin wax candles are burned, they emit trace amounts of organic chemicals, including acetaldehyde, formaldehyde, acrolein, and naphthalene. The amounts differ depending on the quality of the paraffin used, but in some cases it exceeded acceptable levels.
