Most candles on the market are made from a non-renewable resource: paraffin wax, a petroleum by-product. Traditional paraffin candles may also burn off unhealthy fumes, especially if they are scented with synthetic fragrances or have a lead-containing wick (scary stuff!).
The good news is, there are plenty of clean-burning alternatives to paraffin candles. I recently picked up this 100% beeswax candle from Big Dipper Wax Works ($18 at 3R Living in Brooklyn). It was well worth the price, as it burns for 60 hours — much longer than a hot-burning paraffin candle.
Beeswax candles have a delicately sweet scent, and naturally clean the air by emitting purifying negative ions.
Beeswax is the purest material for candle making. It’s a renewable resource and its production requires no chemicals and very little energy (except for that of the bees!).
Other beeswax candles are available at Amazon.
