During temperature changes, soy wax will sometimes release excess oil. This often happens after shipping across the country and is known as ‘sweating’. This will not affect the candle, nor usually reappear after the initial burn. To remove the oil, use a paper towel to gently wipe it clean. Common Sense candles are all hand poured and not massed produced. Although every effort is made to ensure consistency, each candle is unique. When using natural vegetable wax, sometimes you may notice darker patches or wet spots in your container. This is not a fault of the candle – simply a characteristic of natural soy wax where the wax has not 100% adhered to the glass. This does not affect the candle in any way. It’s how you know it’s completely natural soy wax.
