Hot wax can be dangerous, so it's best to melt it slowly and at moderate temperatures to minimize risks. The most popular method for melting wax is using a double boiler, but you can also use a slow cooker or solar energy.
Double Boiler
Step 1. Fill a large pot with water.
Pour some water into a large saucepan. If you have a double boiler, fill the bottom part with 2.5 to 5 cm of water. If not, an old large pot will work as well, filled to the same level.
- The pot should be large enough to fit a smaller pot inside.
- Never place wax directly over a heat source. This can cause uneven melting, which is hazardous and can lead to burns or even fires.
- Since water boils at 100 degrees Celsius, the wax in the double boiler will not heat above this temperature, adding an extra layer of safety.
Step 2. Bring the water to a boil.
Place the pot on the stove and bring the water to a boil.
- Avoid placing the pot at the edge of the stove. Hot wax is dangerous, so it’s better to keep the pot further back to prevent accidental tipping.
- If possible, use an electric stove. Gas stoves are also safe, but if the wax reaches its ignition temperature, vapors may ignite from an open flame.
Step 3. Place the smaller pot into the larger pot and reduce the heat.
Put the smaller pot into the larger pot and lower the heat. Set the top part of the double boiler into the bottom part. If you don't have a double boiler, use a smaller metal pot. Reduce the heat so that the water simmers slowly.
- Only use metal containers. Glass and plastic are not suitable.
- Ideally, the top part should rest on the edges of the bottom part, not touching the bottom.
- If it does touch the bottom, place a metal baking pan or something similar underneath to elevate the top part and protect it from heat.[1] X Source
Step 4. Place the wax in the smaller pot.
Carefully place the wax into the top pot. Make sure no water gets inside.
- To speed up melting, you can cut the wax into smaller pieces.
Step 5. Take your time.
Don't rush. The pieces of wax should melt gradually. Depending on their size, this process can take anywhere from 30 minutes to several hours.
- Never leave the melting process unattended.
- Use a thermometer to monitor the temperature. Wax melts at 63-64 degrees Celsius. Don't let the temperature exceed 70-75 degrees, or it may darken and lose its scent.[2] X Source
- Periodically add water to the bottom pot, as it will evaporate. The water in the double boiler should not run dry during the melting process.
Step 6. Use the melted wax.
Once the wax is melted, you can pour it into molds or use it as desired.
Slow Cooker
Step 1. Fill the slow cooker with water.
Pour water into the slow cooker, filling it to a depth of 5 cm.
- To speed up the process, you can pre-boil the water in a kettle.[3] X Source
- A slow cooker is even safer than a double boiler since it heats slowly.
- In theory, you can melt wax directly in the slow cooker without a water bath if the bowl is non-stick.
- However, it’s better to use a water bath to protect the wax from direct heat and to make it easier to use later.
Step 2. Place the smaller bowl into the slow cooker.
Set the smaller bowl into the large water-filled container. Ensure no water gets into the smaller bowl.
- Only use metal cookware. Plastic and glass are not suitable.
- This method works best when the metal bowl sits at the bottom of the larger bowl, not floating in the water.
- After placing it, the slow cooker lid should close completely. If it doesn't, use a smaller bowl.
Step 3. Place the wax in the bowl.
Put the wax in the top, smaller bowl.
- You can cut the wax into smaller pieces to speed up the process instead of placing a whole block. Melting in a slow cooker takes time, and cutting the wax will help make it safer.
Step 4. Wait for the wax to melt.
Cover the slow cooker with a lid and set it to a higher temperature. Melting wax in a slow cooker usually takes several hours.
- You can melt the wax on a low temperature, but it will take longer.
- Ensure the slow cooker is covered during the melting process.
- Use a kitchen thermometer to monitor the temperature. Wax melts at 63-64 degrees Celsius. Do not let the temperature exceed 70-75 degrees, or it may darken.
Step 5. Use as desired.
Once the wax is fully melted, you can pour it into molds or use it as you see fit.
- If you don’t plan to use all the melted wax at once, you can keep it warm by removing the lid and lowering the temperature.
Solar Energy
Step 1. Line a cooler with foil.
Line the inner walls and bottom of a cooler with aluminum foil.
- Aluminum foil reflects sunlight, creating heat inside.
- Choose a foam container instead of plastic, as foam is an insulator and retains heat.
- Solar heat is safe and eco-friendly. It should be warm enough inside the bag, but not hot enough to ignite the wax.
Step 2. Place the wax in the container.
Put the wax in the lined cooler. Cover it with glass or clear acrylic and secure it with tape.
- Cut the wax into smaller pieces to speed up melting.
Step 3. Position the cooler in a sunny spot.
Place the cooler in direct sunlight in the warmest location. Avoid placing it in the shade or near moisture sources.
- Choose a warm sunny day. Do not attempt to melt wax on cloudy or rainy days.
- If you’re not planning to melt wax in the summer, keep the cooler indoors in the warmest and sunniest spot. You can take it outside in the summer.
Step 4. The wax melts slowly.
Leave the wax for several hours. Check the cooler every 20-30 minutes.
- Do not leave melting wax unattended.
- Start the process early in the morning or at noon so the wax has time to melt under the sunlight.
- Monitor the temperature with a thermometer. Wax melts at 63-64 degrees Celsius. Do not allow the temperature to exceed 70-75 degrees, or it may darken.
Step 5. Use as desired.
Once the wax is melted, you can pour it into molds or use it as needed.
