What are Wet Spots in Candles?
The term “wet spots” in candle making refers to the spots or patches in container candles that appear to have air, or a wet spot showing through the glass or transparent container and the candle wax. Wet spots are extremely common and are one of the most common complaints among candle makers. However, wet spots will not inhibit the functionality of your candle, just the aesthetic appeal.
What causes Wet Spots?
1. Pouring hot candle wax into too cold of a container.
2. Pouring your melted candle wax at a temperature much cooler than what is suggested.
3. Using a pillar/votive wax for container candles instead of a container wax that is formulated for that purpose.
4. Cooling your candles too fast; subjecting your candles to an environment which has drafts or is lower than 70-72 degrees.
5. Pouring candle wax into dirty containers.
How to Avoid Wet Spots?
1. Try to eliminate or prevent wet spots by thoroughly washing and drying your containers before using. This will get any dust or debris out that may have fallen into your jars.
2. Be sure to use a container wax so that your wax adheres properly to your container. Votive/pillar waxes are not suggested for container candles. Wax like Golden Foods Soy Wax 464, is a great start. This type of soy wax has a wonderful adhesion to glass containers, therefore minimizing the chances of getting wet spots.
3. Heat your jars/containers at the lowest setting on a cookie sheet in the oven for twenty minutes prior to filling them. This also allows for the candle wax to cool slowly which allows for better adhesion to the container.
4. Another thing that tends to reduce the occurrence of wet spots is pouring your candles inside the box the candle jars came in. This helps to insulate your candles while they cool slowly. Allow your candles to set up at room temperature, in a room that has no drafts.
5. If you start to see the wet spots taking place as the candle is cooling, this means you should consider increasing your pour temperature. Testing with a thermometer is key here. Follow the manufacturer’s recommended pour temperature.
