After 4 attemps, this version works perfectly.
Tips for a successful result:
- Prepare a bowl of water before making the candle.
- After filling in candle liquid in half, shake the mold gently before fill it to full.
- Fill it to full and wait it to cool down for a few seconds, the candle will shrink a bit during solidification process.
- Fill a few more drops, and repeat a few times until the surface is flat.
- Put the mold in water to help it cool down faster.
- Wait at least 20 minutes before opening the mold. The candle needs to be completely cooled down.
- Maybe moistering the mold before use can help unmolding.
