What Causes Soy Candles to Sink?
Soy candles sinking in the middle is a common problem for candle makers, especially when working with natural waxes. The sinking typically happens during the cooling process, and while it can be a bit frustrating, it’s easy to resolve once you understand the cause.
At Karessa Candles, we take extra care to ensure that our soy candles maintain their perfect shape and burn beautifully, but we also know that sinking is a concern for DIY candle makers.
How Can Temperature Affect the Candle’s Shape?
1. Pouring Temperature
When making soy candles, the temperature at which you pour the melted wax plays a huge role in the final result. If the wax is too hot when poured, it can cause sinkholes or indentations to form in the center of the candle as it cools.
2. Cooling Rate
Soy wax needs to cool slowly and evenly. If your candle cools too quickly, you might notice a sinkhole or crack in the middle. A rapid cooling rate can cause the top layer of the wax to solidify before the bottom has fully set, leading to a hollow center.
Solution:
Ensure you’re pouring your soy wax at the correct temperature, usually around 120-130°F (49-54°C), and allow your candles to cool at room temperature for an even set. At Karessa Candles, we follow precise temperature guidelines to avoid common issues like sinking.
How Can Fragrance Oils Affect the Sinking of Soy Candles?
When you add fragrance oils to your soy wax, it can sometimes cause the wax to behave differently. Some fragrance oils can alter the texture of the wax, causing it to shrink or sink when cooling.
Solution:
Make sure to use fragrance oils that are designed for candle making, and only add them at the correct temperature. Generally, it’s best to add fragrance oils when the wax is around 170°F (77°C), which will help to avoid issues with sinking and ensure a smooth finish.
Can The Wick Size Contribute to Sinking?
Another factor in the sinking of soy candles is the wick size. If the wick is too large, it can cause the candle to burn too quickly, leading to uneven burning and potentially creating sinkholes in the center.
Solution:
Use the appropriate wick size for your container size and wax type. Our luxury soy candles are carefully crafted with the right wick size to ensure an even burn and prevent common issues like sinking.
How Can I Fix Sinkholes in Soy Candles?
If you’ve already poured your soy candles and noticed a sinkhole or sinking in the middle, don't worry! You can fix the problem by following these simple steps:
1. Re-pour Wax
Re-melt some extra wax and carefully pour it over the surface of the candle. This will fill in any sunken areas and create a smooth, even surface.
2. Use a Heat Gun
If the candle has already cooled but you notice minor indentations, use a heat gun on the surface to gently smooth out any imperfections and create an even top layer.
How to Prevent Sinking in Future Soy Candle Creations?
To prevent sinking in future candles, consider these tips:
-
Pour at the Right Temperature: Ensure the wax is the right pouring temperature.
-
Cool Slowly: Allow your candles to cool at room temperature away from drafts or temperature fluctuations.
