When choosing an eco-friendly candle to burn in your home, it's always best to look for non-paraffin wax candles like soy, beeswax and coconut. But the wick itself is important, too. Though metal wicks are less common than they used to be, make sure your wick is metal-free; you can feel it with your fingers, since the metal can be woven into the wick fibers. Also consider a wick that contains no cotton. New candles use a strip of wood, which crackles like a real fireplace and doesn't produce any soot or ash when lit.
