Pure beeswax candles are the best candles you can buy - in my opinion, anyway! They're the best-scented candles, and they emit the best light - a cheery, steady, sunny glow, free from the constant flickering of other types of candles.
And beeswax candles smell great whether they're lit or not. That's because of the wonderful honey-like scent that is a natural component of beeswax.
Of course, beeswax candles have been in use for many centuries. But it's not only because of tradition that candles made with beeswax are the preferred choice of so many. Beeswax just happens to be an excellent natural fuel that burns without the sooty smoke produced by far inferior waxes such as paraffin.
It's true that beeswax candles won't pollute your indoor air with smoke. But many believe that they will actually help to purify your air.
The theory is that pure beeswax candles emit negatively-charged ions when burned.
The negative electrical charge of these ions causes them to bind to the positive charge of other ions in the air. (It's sort of like the negative pole of a magnet attracting the positive pole of another magnet.)
You can think of the positive ions as 'bad' ions, because they tend to contain indoor pollutants - dust, allergens, and assorted toxins floating around in the air.
When the negative ions emitted from the candle binds with these 'bad' positive ions, the resulting particle falls from the air. As a result, the air is cleaned, or freshened, by burning the candle.
Any truth to this theory? I can't say.
I just consider it a potential additional benefit of enjoying the cheery, homey glow of a pure beeswax candle.
