Candle Air Bubble
My favorite problem!
When you see air bubbles in your candle it usually means that you didn’t tap your wax hard enough before placing the mold into the water bath.
Tap harder! Don’t be afraid!
Tap with your finger or use a spoon.
It should be noted that although this problem is usually caused by weak tapping, this problem can also be caused sometimes as a result of wax being poured too fast.
Therefore, if you continue to get this problem after tapping the mold harder, try decreasing the rate at which you pour the wax into the mold.
