How to remove the candle cleanly from a one-piece plastic mold?
1) Freezer method
Place the mold in the freezer for 20–40 minutes. Remove the plasticine seal, then gently tug the wick while supporting the base to slide it out. If, due to geometry (thin taper candles are fragile), the candle still sticks or cracks, switch to the second method.
2) Hot water / heat gun
Rinse the mold under very hot running water or warm it thoroughly with a heat gun for about a minute, so the candle releases from the mold walls and comes out smoothly.
