many container type personalized candles on the market almost have no bubbles, and are very smooth after being extinguished and solidified. In this case, although the product is advertised as soybean wax candle, it is very likely to add paraffin or shrinkage inhibitor, etc. personalised candle wholesale only adds essential oil or essence. You can still smell the natural flavor of soybean wax by careful smelling.
when a candle burns, carbon deposits will appear on the center of the candle, which is the characteristic of soybean wax and will not affect the use or fragrance experience. If the carbon deposit is too large, you can cut it off with a candle scissors.
