When pillar candles sweat, it refers to the formation of small droplets of liquid on the surface of the candle. This phenomenon is commonly known as "candle sweating" or "candle condensation." There are a few possible reasons why your pillar candles may be sweating:
1. Temperature Changes: Pillar candles can sweat when there are significant temperature fluctuations in the environment. When the temperature rises, the wax expands, and as it cools down, it contracts. This contraction can cause moisture in the air to condense on the surface of the candle, resulting in the appearance of sweat.
2. Humidity: High humidity levels in the surrounding environment can contribute to candle sweating. Moisture in the air can be absorbed by the wax, leading to the formation of droplets on the candle's surface.
3. Poor Quality Wax: Lower quality or improperly formulated wax may be more prone to sweating. Some waxes may have a higher oil content or may not be properly blended, which can result in the formation of sweat-like droplets.
4. Improper Storage: If your pillar candles are stored in a location with fluctuating temperatures or high humidity, they may be more likely to sweat. Improperly stored candles may absorb moisture from the environment, leading to sweating.
While sweating does not affect the functionality or burnability of the candle, it can impact the appearance. If you prefer to minimize or prevent candle sweating, here are some suggestions:
1. Store Candles Properly: Keep your pillar candles in a cool, dry place away from direct sunlight and extreme temperature changes. Ideally, store them in an airtight container or wrap them in plastic to protect them from moisture in the air.
2. Reduce Humidity: Use a dehumidifier or improve ventilation in the area where the candles are kept to reduce humidity levels.
3. Choose Quality Wax: Opt for high-quality pillar candles made from properly formulated wax. Be sure to purchase candles from reputable manufacturers or make them using quality candle-making supplies.
4. Avoid Sudden Temperature Changes: Try to minimize exposing your pillar candles to rapid temperature fluctuations. For example, avoid placing them near air conditioning vents or drafts.
It's important to note that slight sweating on pillar candles is a natural phenomenon in certain conditions and may not be entirely avoidable. However, by following these suggestions, you can reduce the occurrence of sweating and maintain the overall appearance of your pillar candles.
