Crafting Wax Melts with Clamshell Molds: A Simple Guide

Wax melts have become a beloved way to infuse homes with delightful aromas, offering a flame-free alternative to traditional candles. Using clamshell molds, crafting your own wax melts is not only simple but also incredibly satisfying. Here's a step-by-step guide to making your own wax melts, ensuring you can enjoy your favorite fragrances anytime.

Step 1: Gather Your Materials

  • Wax  


    For wax melts, soy wax or a blend designed for melts and tarts, such as the Ecosystem RCX Melt Blend or Golden Wax 494, is perfect. These waxes offer good scent throw and are easy to work with. HPM is a great option too.

  • Fragrance Oil  

    Fragrance Oil

    Choose high-quality fragrance oils that are compatible with your wax and safe for use in home fragrance products. The fragrance load can typically range from 5-10%, depending on the wax's maximum fragrance capacity.

  • Equipment


    Melting Pot, Thermometer, Stirring Utensil, Scale: Essential tools for accurately measuring and safely melting your wax and fragrance mixture.

Step 2: Melt the Wax

Using a double boiler or a melting pot, slowly melt the wax to the manufacturer's recommended temperature. For instance, the Ecosystem RCX Melt Blend should be melted to about 47-53°C, ensuring the wax is completely liquified without overheating.

Step 3: Add Fragrance and Dye

Once the wax is melted, allow it to get to the recommended fragrance addition temperature, typically around 65-70°C for many wax blends. Add your fragrance oil and dye, if using, and stir thoroughly for a consistent blend. You may want to experiment with adding dye chips to the clamshell for a sprinkles type effect.

Step 4: Pour the Wax

Carefully pour the wax into your clamshell molds. Pouring at a slightly lower temperature, around 45-60°C depending on the specific wax used, can help reduce the chance of bubbles and ensure a smooth surface. Lowering the temperature will also reduce the chance of the clamshell warping with heat.

Step 5: Let It Set

Allow the wax to cool at room temperature. This process can take several hours. The wax will harden and become opaque as it cools. The larger the melt the longer it will take to cool. If you are making a lot of melts in a batch, remember to space out the clamshells to allow even cooling.

Step 6: Close and Label

Once fully set, close the clamshell mold. You can then label your wax melts with fragrance notes, branding, usage instructions, and any necessary safety warnings such as CLP.

Tips for success

  • Test Your Melts: Before making a large batch, create a test melt to ensure the fragrance throw meets your expectations.
  • Temperature is Key: Pay close attention to the temperatures for melting, adding fragrance, and pouring. These can significantly affect the quality of your wax melts.
  • Customize: Experiment with different fragrances, dye colors, and even blends of wax to create unique melts that stand out.

Creating wax melts with clamshell molds is a fun and creative process that allows for endless customization. By following these steps and incorporating your personal touch, you can enjoy beautifully scented spaces or even start your own line of home fragrance products. Happy melting!
