How to Make New Candles from Old Candles

Go Gingham: How to make new candles from old candles

“In case you ever want to live off the grid,” was the answer I gave my 15-year-old son as the reason he should make candles with me. As you can imagine, this was met with a jaw-dropping, wide-eyed dazed look that comes from a teen who would like nothing better than to be plugged-in and on-the-the grid much more than his parents allow. But guess what? This candle making project was more fun than anyone imagined and our house is a burning inferno these days just so we can make candles again – sooner rather than later!

I’ve been saving candles for years. Whenever the candles get to the bottom (and have cooled off) I toss them in a bag that I keep stashed in my basement, rather than throwing them in the trash. Why waste all that wax and resources? Yes, all sizes, all colors, and all types get stashed away – except tea-lights. Those seem to burn down pretty well on their own.

Save old candles to make new ones
My stash had all sorts and types of candles.

And smaller ones…

All different shapes, sizes, and colors went into our project.

Materials needed to make new candles

  1. old candles (you could use new wax, too, if you don’t have a stash of old)
  2. candle wick (available at craft supply stores)
  3. large can or old pot to melt wax, over a double boiler
  4. drop cloth, in case of spills
  5. weights for bottom of candle, to attach wick (I used washers)
  6. candle molds or ceramic pots or terra cotta pots, or old jars (whatever you have and what you think would look good with a candle in it)
  7. pencils or twigs for tying wick to, resting on top of container
  8. tools – scissors, hammer, chisel, hot pads, outdoor cooker

Make sure to do this somewhere that can handle wax spills and drips. Even though everyone was careful and I had put down an old shower curtain, we still had plenty of drips and spills.

We started by chopping the old candles into smaller parts and removing the old wicks and metal parts on the bottom.

This was more enjoyable than my kids thought it would be.

It seemed like my kids really enjoyed hammering the old candles and breaking them apart.

Wax was flying everywhere when this was going on!!

After the candles were broken up, we put them in an old coffee tin to melt the wax. Make sure to use a double boiler so your wax doesn’t get too hot. We used our outdoor propane gas cooker to melt the wax.

I found this big canning pot and rack at an estate sale. Use a stick to stir and stand back – this was very hot!

Use a double boiler and be careful – this was really hot.

Make sure to use candle wicking. My sister and I made candles years ago and we didn’t know to use candle wick and we made them using nylon string. That didn’t work and we had to do the entire project over. It was fine because I was doing it with my sister but it was time consuming to do and re-do.

Use candle wicking
Make sure and use candle wicking.

Have your candle forms ready to go with wick and weight before you melt the wax. We had so much fun melting the wax that when it was done, there was a little scrambling to get the forms ready.

To keep the candle wicking at the bottom of the container, I used washers. I also use these for curtain weights when sewing so I had these in my sewing studio.

I used these washers and attached them to the candle wick to add weight and keep the wick in place.

Attach the washer to the candle wicking and then attach it to a pencil or stick to keep it in place.

Make sure to get the washer in the center – or close.

After the wax melted completely, it was time to pour it into the forms.

Hot wax melted down and ready to be poured into the containers.

Here’s where that old shower curtain/drop cloth came in handy! It was messy.

Very carefully pour the hot wax into the prepared containers.

We left the candles outside on the table to dry.

Hot wax poured into our containers – now they need to dry.

It was hard not to play with the wet wax while the candles dried….

For some reason the tall, glass containers sank down in the center. This didn’t work out very well.

Notice the tall containers? The wax settled and left a gap in the center.

These terra-cotta containers turned out really well.

Here’s what worked making candles:

  • The best containers were old terra-cotta flower pots. I don’t know if it was the wide mouth or the terra-cotta material but they seemed to work out really well.
  • Doing the entire project outside! From chopping the old candles to melting the wax to pouring it into the forms to all the playing in the wax that my kids did – I was so thankful to be outside with the mess there and not inside the house in our kitchen.

Here’s what didn’t work making candles:

  • Large, tall glass containers didn’t work as well as the wide mouth containers. I wouldn’t use tall glass jars again.
  • More hot, melted wax probably should have been added after the initial amount was poured in, and dried. Once the initial wax was dry, I should have then added more to fill it up. I think this would have kept the wax filled to the top and not so sunken in. (To be honest, I was ready to wrap the project up and didn’t feel like doing this!)
  • The inexpensive candles that had hard, colored wax on the outside probably should have been tossed into the garbage instead of melted. The wax (or whatever it was) took longer to melt and didn’t add to the color. It was probably a bad chemical that we all breathed in and shouldn’t have!!
  • Don’t use containers that have ridges and expect to get the candle out. My old coffee tin with ridges won’t release the candle. It’s fine because we’re burning the candle with it still inside the coffee tin but a smooth surface lets the candle come out.
  • Next time, I think I’ll use a rag to drape around the container when the wax is getting poured in. It was messy to pour and a hassle to clean off the containers. Mostly, I just left it there.

The candles are a nice addition to our front porch. We spend lots of time on our front porch during the summer.

I do hope to make candles again – soon. We’ve been enjoying them indoors and out. Our front porch looks pretty with the new candles and we’ve been enjoying them out there!

Have you ever made candles? What tips would you add?

  1. Nice idea – now I wish I’d kept the drawer full of candles that the mice chewed on, instead of throwing them out. It would have been perfect for this.


    1. Next time, Heidi! Why do mice chew on candles? I found something in the garage mice chewed on and it was a mess to clean up so I’m sure candles were messy, too.


  2. GREAT post, Sara!!!! I want to make candles. Every so often, in a fit of cleaning up, I toss all the yucky candles, but now I will keep them and make new ones!


    1. My stash is far away from those fits of cleaning! I had one of those fits this weekend – clearing clutter away, filing, shredding – good times at our house 😉


  3. I freecycled my ‘stubs’ – so someone else could do this. I just imagine my pot to double boil would become solely for candles, and I’m not THAT into making candles! Great activity though!


    1. That’s a great spot for old candles, Sarah! I hear ya’ about the double boil pot!!


  4. Have never made the candles before – but did make new crayons with old ones! My kids would love the bashing part as well. 😉

    1. Kerry, yes, kids love the bashing part!! I like swinging a sledge hammer into a wall when starting a house project so I can understand. Great idea on making new crayons – very clever!


  5. I am so glad I am not the only one who holds onto candle stubs to make more candles. Am wondering where you found that 100 yd wick. I tried Michael’s but their wicks are quite expensive and, I hate to admit this, I have made my own string wicks wrapped on wire from twisty ties……


    1. Sue, I did get mine at Michael’s but it was over 10 years ago. It will last me forever! I see it regularly at estate sales, too, so you may have luck second-hand. If what you’re using works, go with it! My daughter tried a cotton string that burned, too. I think because my first experience with making candles left me having to start completely over it left me with the feeling that I didn’t want to experiment.


    1. Michelle, we said the same thing! My daughter was the queen of the crayon melter at preschool. We could have wallpapered a room in our house!!


  6. A very good tip is melting the old candels in a old teapot, Very littel mess =)


    1. Cathrine, that is brilliant! I have an old teapot that is in my laundry room now – the handle broke off but it’s too pretty to part with! Melting wax is just the ticket. I also like that I wouldn’t have to wait until I had a huge slew of wax to melt.
      Thanks for the tip!
