During manufacturing, the soybean oil that eventually becomes soy wax is constantly stirred and agitated, which allows air into the oil. Occasionally, some of that air gets trapped in the wax during the flaking process, and is released when the wax is melted down for candle making. If your wax contains excess air, you might see a slightly foamy look on the surface while the wax comes to temperature, visible bubbles rolling to the surface as the wax is heated, or audible popping sounds, similar to frying food. You will probably not notice the air bubbles most of the time, but it can sound alarming to hear the popping noises while the wax melts.
Allow air bubbles in candle wax to release
Slowly stir the wax to help release any trapped air. Continue until the popping noise stops and there are no visible bubbles.
Be gentle with stirring candle wax
Stirring the wax too briskly will create air bubbles. Stir slowly to avoid adding any extra air.
Slowly heat candle wax to 85-95°C
If you hear a lot of popping, heat the wax to 85-95°C to help release the trapped air.
