One of the most famous benefits of soy candles is how clean they burn. Soy wax doesn’t not produce the black soot like paraffin does. While some might say “no soot”, it’s actually “very little soot”. Everything that burns puts off smoke, and soy candles are no exception. However, the amount of smoke released from soy wax is so minimum, there are very few that notice it.
If your candles leave soot, even a little, it could be that its not pure Soy Wax, maybe a Soy / Paraffin mix may have been used. To the best of Wendy’s knowledge, her wax is pure soy wax Another reason might be the wicks used. Even as Candle-Talk says lead is no longer used in wick manufacture, there can be some zinc and that can smoke. Wendy only uses cotton candle wicks, although special orders are taken for candles with “wood wicks”. These burn with a crackle & popping sound and can be soothing when burning your candles.
You may be surprised by this, but soy wax candles can be more cost effective than paraffin, not only in quality, but in quantity too. Soy not only burns cleaner, but slower too. A soy candle can burn up to twice as long (sometimes even more!) than paraffin, giving you twice the candle
Strange terminology, but soy wax hold the scent longer and better (without the “fuel smell” of paraffin). Also when burning the scent hangs in the air, and a lot less scent is needed in the manufacture and making of the candles.
