What Are Candle Moulds?
A candle mould (or mold) is a reusable form that shapes molten wax as it cools and hardens. The right mould helps you achieve clean edges, an even surface and reliable demoulding. Choice of mould depends on design detail, wax type and the release characteristics you need.
Types of Candle Moulds
Silicone Candle Moulds
Flexible and durable, silicone captures fine detail and offers easy, clean release. It is suitable for soy wax, beeswax and paraffin blends, and is the preferred option for sculpted or floral designs. See the latest designs in our Premium Candle Moulds Collection.
Plastic Candle Moulds
Rigid plastic moulds are affordable and good for simple shapes such as votives and classic pillars. They may require a light application of mould release spray for best results.
Metal Candle Moulds
Aluminum and tin moulds are long-lasting and excellent for pillar candles. They hold heat evenly during cooling and are commonly used with paraffin or blended waxes.
How to Use Candle Moulds Properly
- Clean and dry the mould thoroughly before use.
- Center and secure the wick using a holder or bar.
- Heat your wax to the manufacturer’s recommended pour temperature for the chosen wax type.
- Pour slowly to minimise air bubbles.
- Allow the candle to cool at room temperature; avoid refrigeration to prevent cracking.
- Demould gently. With silicone, peel the sides away first, then release the base.
For consistent results, test each new formula and container size. Trim wicks to approximately 6 mm (¼ inch) before burning.
Silicone vs Plastic Candle Moulds
| Feature | Silicone Mould | Plastic Mould |
|---|---|---|
| Flexibility | Very flexible | Rigid |
| Detail Capture | Excellent for intricate shapes | Moderate |
| Ease of Release | Clean release, usually no spray needed | Often benefits from release spray |
| Best Use | Sculpted and decorative designs | Simple pillars and votives |
| Wax Compatibility | Soy, beeswax, paraffin blends | Paraffin and blends |
Common Mould Issues and Fixes
- Cracking: Cooling too quickly. Allow natural room-temperature cooling.
- Air bubbles: Pour temperature too high or pour speed too fast. Lower the temperature and pour steadily.
- Rough surface: Mould not fully clean or wax overheated. Clean, then pour within the recommended range.
- Uneven sides or dents: Wick not centred or wax blend too soft for the design. Re-center the wick and review the wax blend.
Best Wax Choices for Moulded Candles
Different waxes perform differently in moulds:
- Soy Wax: Smooth surface and clean burn; popular for decorative moulds.
- Beeswax: Naturally firm and well-suited to pillars and taper moulds.
- Paraffin Wax: Produces crisp edges and strong scent throw.
- Blends: Combining soy and paraffin can balance natural appeal with detail retention.
