Create Your Own Custom Embossed Candle Mould
Bring your brand, message, or special words to life with our fully customisable rectangular block silicone mould. Whether it’s a logo, name, short quote, or unique font you love—simply email us your design or tell us your desired text and font, and we’ll turn it into a one-of-a-kind embossed mould, perfect for candle making.
Made from premium platinum-cure silicone, these moulds are tear-resistant, long-lasting, and can withstand temperatures up to 230°C. With proper care, platinum-cure silicone moulds can last for decades—making them a reliable choice for both hobbyists and professionals.
To use, thread your wick through the top and bottom of the mould to keep it centred. Pour in melted wax and allow your candle to cure overnight before unmoulding.
Pro Tip: For best results, preheat your mould with a heat gun just before pouring. This helps the wax flow into all the embossed details and minimises air bubbles.
Each mould includes a custom-fitted 3D printed support case to help maintain its shape during pouring and curing. Silicone moulds naturally expand slightly when filled—this case ensures clean, consistent results. Made from PLA plastic, these supports should be kept away from heat as they will warp under high temperatures. Extra support cases are available for purchase if needed.
Perfect for small business branding, event favours, or personalised gifts—your custom candle design starts here.

Mould Perfomance & Storage
The physical life of the mould depends on how you use it (materials cast, frequency, etc.). Casting abrasive materials such as concrete can quickly erode mould detail, while casting non-abrasive materials, such as wax, will not affect mould detail. Do not over-stretch or use any abrasive tools or fingernails when demoulding.
Before storing, the mould should be cleaned with a soap solution and fully dry. Two part moulds should be assembled. Moulds should be stored on a level surface in a cool, dry environment to maintain its original shape.
Disclaimer: mould is poured and trimmed by hand and therefore may have some minor exterior imperfections.
How To Use
Silicone Candle Moulds:
Thread the wick through the centre of the mould and secure it in place with a wick holder. For best results, gently warm the inside of the mould with a heat gun before pouring, especially for designs with fine details, lettering, deep textures, or narrow areas. This helps the wax flow into small details more evenly and can reduce trapped air bubbles and visible pour lines.
Pour in your melted wax and allow it to cool and fully set before carefully unmoulding. Depending on the wax used, a second pour may be required to level the base. Always keep the heat gun moving and avoid overheating the silicone.
Acrylic PVC Candle Moulds:
Thread the wick through the wick hole and secure it with a wick holder. Seal the hole with Blu Tack to prevent leaking, then pour in your melted wax. A second pour may be needed depending on the wax used. Allow the candle to set fully before unmoulding. If needed, gently squeeze the sides of the mould to help release the candle.
Concrete Trays & Vessels:
Mix your chosen casting material according to the manufacturer’s instructions, then pour it into the mould. Gently tap the mould to help release trapped air bubbles and allow the piece to cure fully before demoulding.
If using the finished vessel for candles, apply at least two coats of a suitable heat-resistant sealer to the inside and outside. Allow the sealer to dry and cure completely before adding wax.
Mould Performance & Storage
Our silicone moulds are handcrafted from premium platinum-cure silicone, chosen for its durability, flexibility, tear resistance, and long lifespan. While the silicone can withstand high temperatures, prolonged exposure to excessive heat should be avoided.
Mould life will vary depending on the material used and frequency of casting. Abrasive materials such as concrete may gradually wear down fine details, while non-abrasive materials such as wax are much gentler on the mould. Avoid overstretching and do not use sharp tools or fingernails when demoulding.
Before storing, wash the mould with a mild soap solution and allow it to dry completely. Two-part moulds should be reassembled and stored flat in a cool, dry place to help maintain their shape.
Please note: Each mould is poured and trimmed by hand, so minor exterior imperfections may occur.
