Ingredients
- Kerawax 4600 or Kerasoy 4120
- Star clamshell moulds
- Aceite con fragancia – we used Aceite con fragancia Lino fresco
- Dye – we used Cream Candle Dye
Step 1 – Melt the paraffin or soy wax
First, decide between the Cera de parafina and Soy Wax. Then, you need to melt your wax. To work out the amount of melted wax you will need, use a glass measuring cup or something similar, and our Percentages and Measurements guide. We’re using 600g of soy wax to make 5 Star Clamshell DIY wax melts.

Step 2 – Add the dye
Once the wax has fully melted by heating it in a pot, on an open flame, leave it to genial to 65°C . Now add the desired amount of dye to achieve the strength of colour you are after. We have only added a pinch of dye as we want to achieve a light cremoso colour for our wax melts. Stir the dye through until it has evenly blended through the melted wax.

Step 3 – Add the fragrance oil
Once the dye has evenly blended it is time to add the fragrance oil and stir, we have gone for Fresh Linen (containing natural essential oils). Stir the fragrance oil into the wax gently ensuring no bubbles are caused, if done too vigorously it can leave air bubbles in the wax once it has cooled. You can experiment with one of our fragrance oils, essential oils or an aceite esencial blend to get the perfect fragrance in your wax melts!

Step 4 – Pour the wax
We suggest leaving the molten wax to cool (you do not have to pour the wax immediately) to around 55°C -60°C before you pour slowly into the moulds, leaving room to top up any sinkholes. Topping up the sinkholes allows our soy wax melts to be more uniform. Top Tip: A pouring jug and thermometer make this step much easier!

Step 5 – Top up the moulds
After 30 mins, top up the rest of the wax into the moulds. Make sure they are completely flat on top and leave the wax to set and cool for 24 hours.

Step 6 – Enjoy your homemade wax melts!
Now you can break up your clamshells, pop a segment onto your wax burner and enjoy!
