Preparing the Double Boiler
To prepare a double boiler for candle making, you'll need a heat-safe container, such as a metal pitcher with measurements and a handle for easy pouring.
The type of container you choose is important, as it will affect how easily you can gauge the amount of wax left to pour and prevent water from splashing inside and ruining the wax.
A metal pitcher with a spout is ideal, as it makes pouring the wax easier and reduces the risk of spills.
You can use a double boiler setup in two ways: by placing your pouring pot directly in the outer saucepan and melting the wax there, or by melting the wax in a melting pot and transferring it to a pouring pot with a ladle.
The second method is recommended, as it allows for multiple colors and reduces the risk of water getting into the pouring pot and ruining the candles.
To make transferring wax from the melting pot to the pouring pot easier, use a large ladle with a pouring lip.

Melting the Wax
Melting the wax is a crucial step in making candles with a double boiler. You'll want to place the wax in the smaller pot or bowl, breaking it into smaller pieces if necessary.
To melt the wax, heat the water in the larger pot on medium-low heat. It's essential to monitor the temperature with a thermometer, ensuring it doesn't exceed the recommended melting point for your specific wax type.
The melting point varies by wax type, but most require heating to between 160 and 185 °F. Be cautious not to exceed this temperature, as it can be dangerous.
Here's a quick reference guide to melting points for different wax types:
Keep an eye on the wax as it melts, stirring it gently to ensure even heating. Once fully melted, you can carefully add colorants and scents as desired, following manufacturer recommendations for quantities.
Melt the Wax Completely
You'll want to heat the wax until it melts completely. This can take anywhere from a few minutes to several hours, depending on the type and amount of wax you're using.
Soft wax types like soy will melt faster than hard wax types like paraffin and beeswax. To ensure even heating, stir the wax gently as it melts.
Maintain a simmer, not a rolling boil, to prevent overheating. If the wax starts to boil hard, add a little more water or lower the heat.
The ideal temperature for melting wax varies by type. Most waxes require heating to between 160 and 185 °F. Be sure to check the melting point guidelines for your specific wax type.
Here are some general guidelines for melting temperatures:
Don't go above the flashpoint, the temperature above which it becomes dangerous to heat the wax. This temperature varies by wax type, so be sure to check the manufacturer's guidelines.
Temperature for Adding Fragrance Oil to Candle
You should add fragrance oil to your candle at 185°F. This is the ideal temperature for the fragrance oil and dye to bind with the wax.
At 185°F, the fragrance oil and dye can bind with the wax, ensuring a consistent and safe candle.
If you stir too aggressively after adding fragrance oil, you'll introduce air bubbles that can ruin the appearance of your candle.

A silicone spatula is a good choice for stirring because it's easy to clean and won't introduce any unwanted materials into the wax.
Remember to turn off the heat after adding fragrance oil, as you won't need to continue warming the wax.
To recap, the key temperature to remember is 185°F for adding fragrance oil to your candle.

Stir slowly, as aggressive stirring can introduce air bubbles that will show up on the surface of your candle later. I like to use a silicone spatula to stir because it's easier to clean than a wooden spoon.
You can turn off the heat after adding fragrance oil and dye, as you won't need to continue warming the wax.
Before pouring, make sure to remove the pitcher from the double boiler and let it cool down slightly. This will prevent you from getting a dip or a sink hole in your candle.
To ensure a smooth pour, dry the bottom of the pitcher so that you don't drip any water into the candle.
Here's a quick rundown of the steps:
- Add fragrance oil and/or dye at 185°F
- Turn off the heat
- Stir slowly
- Remove pitcher from double boiler
- Dry bottom of pitcher
- Pour when wax has cooled slightly
Making a Candle
Making a Candle is a straightforward process once you have your double boiler set up.
You can move on to the candle making process once you have the double boiler in place. This is a crucial step in creating a stable and safe environment for melting wax.
To set up your double boiler, you'll need to place a heat-proof bowl or saucepan on top of a pot filled with water. The water level should be below the bottom of the bowl to prevent it from touching the heat source.
The Presto Pot is a great alternative to a double boiler, allowing for more efficient candle making. This method uses a specialized pot with a built-in strainer to make the process even easier.
With your double boiler or Presto Pot set up, you can now melt your wax to the desired temperature. The ideal temperature for melting wax is between 160°F and 180°F, depending on the type of wax you're using.
