Silicone Mold and Candle Making
Making your own candle is not only a hands-on process but also a way to control the final result down to the smallest detail. If you are creating a mold and need clay for shaping the original model, the best option is to use non-sulfur clays. By working with high-quality materials, it is possible to achieve a neat and durable finished product.
Required tools and materials
A candle-making project requires a few essential materials and tools. The model can be shaped from non-sulfur clay or sculpting wax. A silicone mold is then created around the model, for example with products from the Mold Star 15 Slow series. You will also need a release agent, a mixing container and stick, candle wax (soy, paraffin, or another wax of your choice), wick, and a heat-resistant container for melting the wax. A thermometer is useful for monitoring the temperature. Optional fragrance and color oils can also be added..
Preparing the model
Begin by creating the model, for example from non-sulfur clay, which can be shaped into a heart or any other desired form. Pay close attention to the surface finish, as even the smallest details will be captured in the mold and appear in the final candle. Once ready, place the model into a suitable container or frame that will serve as the mold box.
Making the mold
Before pouring, apply a thin layer of release agent onto the model’s surface to ensure easy demolding after curing. The choice and need for release agent depends on the material of the model. Mix the silicone carefully according to the manufacturer’s instructions and pour it over the model from the lowest point in a steady stream. To minimize air bubbles, pour slowly and, ideally, from a container with a wide lip rather than a spout. Curing time varies depending on the silicone used, but generally takes several hours—always check the instructions of the specific product.
Candle casting
Once the silicone mold is fully cured, carefully remove the original model. Melt the candle wax in a heat-resistant container or pot using a water bath, and monitor the temperature with a thermometer. If desired, add fragrance or color oils to the melted wax. Place the wick carefully into the mold, ensuring it remains straight during casting. Pour the melted wax evenly into the mold and allow it to cool until completely solidified.
Finishing
After the candle has hardened, gently remove it from the silicone mold and trim the wick to the desired length. The candle can also be decorated or painted with candle paints.
A homemade silicone mold is highly durable and versatile. It can also be used with other casting materials, such as soap base, plaster, or concrete, making it suitable for many different creative projects.
