How To Use a Double Boiler to Properly Melt Wax for DIY Projects

I use wax for dozens of projects. It’s important to know how to melt wax properly because if it’s not done properly, it can be extremely dangerous.
Here’s a fact:
Paraffin Wax has a flashpoint of 390 degrees F. Beeswax has a flashpoint of 400 degrees F. Which means that at these temperatures, if sparked, it could ignite.
Beeswax in particular is extremely flammable. Which means that if any of the melted wax falls onto the burner, it could cause a fire. It’s important to be extremely careful and cautious with all wax.
This is why a double boiler method is essential.
What is a double boiler method?
There are many ways to make your own double boiler. There are two key elements to keep in mind:
- Use a pot to hold the water that will be heated.
- Use any glass object to house the wax that will be melted.
The glass object goes into the water that’s inside the pot. Then the hot water/steam from the water in the pot, melts the wax.
I’ve also used a tin can, which can work, but can be difficult to clean. A glass object, such as a mason jar or glass measuring cup, will be ideal. Don’t use a small glass container, either. Try to use a large glass container so there’s no chance of the wax boiling over.
Here’s a picture of what the double boiler method looks like:

Here are some additional tips:
- Place the jar into the water before turning the burner on.
- Try not to let the water get to a rolling boil. Keep it on low/medium heat.
- The wax should melt slowly with a consistent heat.
- Keep a close eye on the wax and consistently stir until sufficiently melted.
- Don’t let the beeswax get to a boil, once it’s all melted, wait a minute just to make sure then…
- Turn off the burner before you plan to take the jar of wax out of the water.
- Always use oven mitts when handling the glass jar as it will be extremely hot.
Whenever you plan on melting wax, please always use a double boiler method.
Stay safe!
