1. Collect All Used Candles in Glass Jars

Reusing your used candles can be a great way to spruce up the decor in your home. Not only does collecting all of your used candles in glass jars give you more of an organized look, but it also allows you to add a little extra style to your space.

A nice jar full of colorful wax shapes and scents can make any room come alive! 

Remember to use those outdoorsy-looking Mason jars when it comes time to store your burning wares during the summer months ahead.

When grouped, a collection of these vintage jars creates a whimsical scene that’s sure to make guests take notice of any surroundings.

2. Melt the Wax Down Using a Double Boiler Method

If you’re looking to make unique candles, the double boiler method is one of the go-to techniques.

This special technique allows you to melt down your wax in a safe and controlled manner to achieve the perfect consistency.

Using a pot over another pot with boiling water simmers the wax while stirring evenly distributes heat. 

The time needed will vary based on the wax types and thickness, but this ensures a fully melted product that doesn’t have lumps or soap pockets.

Keep an eye on it and ensure the wax isn’t burning or getting too hot! A simple double boiler can be a great way to kick off your homemade candle adventure!

4. Pour the Melted Wax Into a New Candle Mold or Jar

Creating a new candle is such a wonderful and refreshing experience! Watching the melted wax swirl around in the mold or jar as you pour it, you know that something meaningful is being made with your hands. 

There is something special about knowing that you put all your time and effort into making the perfect candle for yourself or a friend.

Watching the wax slowly ripple throughout the jar or mold is an especially satisfying part of this process – it’s like putting together a personal puzzle and waiting to see what amazing design will come out of it.

5. Add Fragrance and Coloring if Desired

Creating your candles can be a fun and creative way to express your style. Once the ingredients are gathered, heat the wax in a double boiler until completely melted.

Then add fragrance and coloring if desired, stirring carefully to mix everything and create a unique combination of colors and smells. 

Pour the melted wax into a mold or jar, then let the candle cool and solidify completely before you enjoy it! With this simple process, you can make beautiful and custom candles that will make your home feel cozy.

6. Trim the Wick to 1/4 Inch Before Relighting Upcycled Candle

When you want to enjoy your upcycled candle again, trim the wick to 1/4 inch before relighting! This is an important step when using any candle, especially your eco-friendly one.

Trimming the wick prevents excessive flames and smoke, ensures consistent burning throughout its life, and helps extend the candle’s lifespan. It may seem like a small step, but it makes all the difference for a bright, safe flame.

Plus, you can feel good that your upcycled candle is made from eco-friendly materials and benefits the environment.

With a little time and patience, you can upcycle your used candles into new ones! This process is fun and engaging and saves you money in the long run.

Not to mention, it’s eco-friendly since you’re reusing materials that would otherwise go to waste. Next time your candle burns down to the nub, don’t throw it out – recycle it!

When should you throw away a jar candle?

Once your candle has melted to roughly 1/2″ of wax, it’s best not to light it anymore.

Candles are crafted with a buffer of excess wax at the end that can be left behind without any issues.

Why should you only burn a candle for up to 4 hours?

Burning your candle for more than 4 hours in a row can lead to what’s called ‘mushrooming.’ This occurs when carbon builds up on the wick, and it causes an unstable flame that is too large and results in smokey air around the container.

Not only will this put soot into the atmosphere, but it could also damage your candle.
