How to Use Polyurethane Candle Molds
Polyurethane candle molds are easy-to-use and we love the fine detail that they give to our finished candles! Here is a list of equipment and step-by-step instructions you will need to use these molds:
- Silicone Mold Release Spray
- Large Wide Rubber Band
- Large Eyed Darning Needle, Wire or Wooden Skewer
- Square Braid Wicking (the size depends on the size of the candle and the type of wax you are using, click here for general guidelines on choosing a wick)
- Mold Sealer
- Wick Bar
- Melting Pot with Pour Spout and Double Boiler Ring
- Wax (we prefer using beeswax in the polyurethane molds because it comes out the easiest but other types of wax can be used)
- Prepare your mold by spraying the inside with a light coating of silicone release spray.
- You will notice a slit on one side of the mold. Carefully align the cut sides of this slit and place a rubber band around near the top of the mold to hold the slit together. The slit is normal and allows for you to easily release the candle from the mold once it is dry.
- Using a large eyed darning needle, thread the wick through the eye of the needle and pull through the wick hole at the bottom of the mold and up through the center of the mold. Alternatively, if you don't have a darning needle, you can push the wick through the wick hole by using a bamboo skewer and then pull it through from the inside of the mold.
- Be sure to leave a couple of inches of wick at the bottom of the candle and seal the wick hole at the bottom using mold sealer. Mold sealer is a putty-type material and will easily attach to the bottom of the mold. Be sure to completely push down the edges of the sealer to ensure the wick hole is sealed and to prevent leaking.
- Secure the wick at the top of the mold with a wick bar by inserting the wick into the notch in the center of the wick bar. Leave at least 3 to 4 inches of wicking trailing from the top of the wick bar. The wick bar will hold the wick tight and keep it centered.
- Place your your wax of choice in a metal melting pot with pour spot. Set up a double boiler by placing a double boiler ring in the bottom of a large pot of water, fill the large pot 1/4 to 1/2 full and then place your wax filled melting pot on top of the ring to prevent the pot from floating and to melt the wax evenly.
- Gently melt your wax over medium heat using a thermometer to monitor the temperature. Melt until all the wax is completely liquid and until it has reached the desired pouring temperature. For beeswax, we recommend to pour at approximately 150 to 160 degrees F. It's important to not heat above 170 degrees F or not to leave melting wax unattended as it is highly flammable. If you are adding color and scent to your wax, add once the wax has reached the desired pouring temperature.
- While your wax is melting, prepare your pouring surface by covering with newspaper or cloth in case of any leaks or overflows. Wax is hard to remove from hard surfaces so this allows for extra protection.
- Once your wax has reached the desired pouring temperature, gently and slowly pour into your prepared mold until it reaches the top.
- Allow your wax to cool checking it every hour for the first 3 to 4 hours. If you notice that a well starts to form around the wick in the center of the candle, gently poke a hole in the surface of the congealed wax near the wick. This is to release any air bubbles that might be captured under the surface. Then "refill the well" by gently and slowing pouring more melted wax (still at the desired pouring temperature or slightly below) into the well making sure that the liquid wax doesn't go up over the dried wax on the edges. Repeat the process of "filling the well" as needed. Beeswax does not shrink very much upon cooling so this process may only need to be done once or twice.
- Allow your candle to dry for 24 hours at room temperature.
- Once your candle is completely dry, remove the rubber band from the mold, the wick bar from the wick at the top and the mold sealer from the bottom of the mold. Gently open the mold by flexing it outward. Push from the bottom while flexing the mold and your candle should pop out.
- Trim the wick on the bottom of the candle so that it is flush with the surface of the wax. Trim the wick on the top of the candle to 1/2 inch from the surface of the wax. Place on a candle holder, light and enjoy!
