Candle Mould Release Tips for Paraffin Waxes:
Add 10% stearin to your candle wax. There are other hardeners you can experiment with too. Besides hardening, these additives shrink the wax. The candle pulls away from the mould slightly, releasing easily.
Leave the candle in a metal mould to set overnight, if possible. In a hurry? Wait until the mould's cool to the touch, and stick into the fridge for an hour. Leave a plastic or acrylic mould in the fridge for 20 minutes. A firm tug on the wick, (no jerking, the wick might snap), and removing the candle's easy. `
Candle Mould Release Tips for Beeswaxes:
The natural stickiness of beeswax makes easy candle removal impossible. Up to 10% beeswax added to paraffin wax, and you can still get the candle out of a 2-sided plastic mould. Any higher percentage of beeswax, and you can forget it.
For metal moulds, use a candle release spray or lotion. These lubricating sprays are available with or without silicone.
For plastic and acrylic moulds, don't use a silicone spray, it might corrode the mould. There are mold release agents suitable for plastic moulds.
Vegetable cooking oil is a natural release agent that works very well in steel, or plastic moulds. Rub a thin layer onto the inside of the mould with a soft, lint-free cloth, (to avoid scratches). Stand the mould upside down on newspaper. Allow the excess oil to drip away. Give it a final rub, and pour your candle.
I've only worked with paraffin and bees waxes, and cannot give you tips for other wax types.
How to Remove a Candle that's Stuck in its Mould
Now I can hear you say, "Yes, but that doesn't help me at all, the candle is ALREADY stuck, how do I get it out?"
Run boiling water over the outside of a metal mould for a few seconds, and pull hard on the candle's wick. The candle should slide out fairly easily. If you're very fortunate, the candle will be undamaged, (but that's unlikely).
With a completely stuck candle, that won't budge, you'll have to put the mould, candle and all, into a metal dish with boiling water, and melt the candle out. Remove the soft candle after a few minutes. This candle mass can be dried off and melted down at a later stage. At least you won't lose all of the wax.
Leave the wax residue in the water to cool down. Lift the wax bits off the water, and dispose of in the bin. Never
throw melted-wax-and-hot-water down the kitchen sink, or drain.
For plastic and acrylic molds, follow the same procedure, but with hot, not boiling water. Pour hot water over the mould, and pull the warm, soft candle, from the mould. Some plastic moulds are heat-resistant up to 110°C (230°F), but some start warping above 82°C (180°F).
Consult the instructions that came with your moulds, to check up on the correct temperatures.
