Soy Candles FAQ's
Soy Wax is non-toxic, burns clean with almost no soot and allows for maximum fragrance throw. Add very long burn times and a large burn pool and you've got the ideal container wax. Our soy wax candles are a great way to get a lot of non-toxic light for less money.
Occasionally, white marks may appear on soy candles due to the nature of the soy wax. The tiny, white looking crystals on the tops and sides of jars are called frosting and are very similar to the frosted look on chocolate. This is a natural characteristic of soy wax and should not be treated as a flaw. It does not affect the quality or burn of the candle.
Since soybean wax has a lower melting point than paraffin wax, it can release excess (fragrance) oils which it cannot hold (usually due to extreme temperature changes due to shipping - i.e. going from hot trucks to an air-conditioned environment or going from cold trucks in the winter to heated stores). You can leave it or wipe it out with a tissue or paper towel. Sweat from soy candles does not affect the burn quality and generally the sweat drops will not show up again after your first burn.
For optimum performance of soy candles, please store in a cool area out of in-direct and direct sunlight. Also, it can be caused by the scent sweating or separating out of the soy candles. We have found that 100% soy wax does not mix well with high concentrations of pure essential oil. Therefore, scented soy candle jars are more likely to sweat when warmed during shipping. This is just the fragrance oils coming to the surface. Some soy candle manufacturers recommended that you blot the top with a Kleenex or paper towel to prevent spillage.
No, your soy candle does not dry out. Frosting is a natural characteristic of soy. It is not a flaw. It is strictly unique to pure soy candles. Often times it is called the "bloom". Actually, many customers are concerned if there is no frosting on their soy candles. It is a way that a customer can tell if their candle is really made with pure, all-natural soy wax. It's part of the soy experience!
Frosting does not seem to affect the scent throw or the burning properties of the candle. You can safely burn a candle with a bloom without worry. Frosting is a particular crystal growth of vegetable oils. It will cause the candle to look dry, which is simply a characteristic of that crystal structure, but has nothing to do with the candle "drying out". To minimize frosting, try to keep your candle out of direct sunlight and florescent lighting. Even changes in the weather can cause additional frosting. It is almost impossible to stop the soy wax from blooming.
How long should I burn my candle?
Soy candle wax has what’s called a memory. That means that when you burn a soy candle and then extinguish it, the next time you burn it, the soy candle wax will melt across as far as it did the first time.
This is why it is so important to allow soy candles to burn all the way across to the edge of the container the first time you burn it before putting it out. This ensures that your soy candle does not “tunnel” as it burns, leaving wax along the sides of the container. A good rule of thumb is to burn your candle 1hr for every inch wide that the candle is. So if you have a 3inch wide soy candle, you may need to burn it for at least 3 hours for a good melt pool.
