Upcycling Your Scented Candle Jar Candles: A Step-by-Step Guide to Making New Candles from Old

Have you ever found yourself with a collection of empty candle jars, each with a stubborn bit of wax clinging to the bottom? You’re not alone. Scented candles are a beloved addition to many homes, bringing warmth and delightful aromas to our spaces. But what do you do with those leftover bits of wax and empty jars? Instead of tossing them out, let’s breathe new life into them. Welcome to the world of upcycling, where creativity meets sustainability, and learn how to transform your old candle remnants into beautiful new candles.

Upcycling is all about repurposing materials that might otherwise be discarded. It’s a creative way to reduce waste, save money, and craft something unique. In this blog post, we’ll walk you through a step-by-step guide to making new candles from your old ones, turning what was once waste into wonderful.

Gathering Your Materials

Before we dive into the candle-making process, let’s gather all the materials you’ll need. Here’s your checklist:

  1. Old scented candle jars with leftover wax
  2. New candle wicks
  3. Wick holders or pencils
  4. A double boiler or a makeshift one
  5. Thermometer
  6. Essential oils (optional for enhancing or combining scents)
  7. New candle containers or molds

Safety first! When working with hot wax, be mindful of these precautions:

  • Always work in a well-ventilated area.
  • Keep a fire extinguisher nearby, just in case.
  • Use heat-resistant gloves to protect your hands.
  • Keep pets and children away from your workspace.
Preparing the Old Candle Jars

Now that you’ve got everything you need, it’s time to prep those old jars.

  1. Remove the leftover wax: One of the easiest ways to do this is by using the freezing method. Place the candle jars in the freezer for a few hours. Once the wax is frozen, it should pop out easily with a little help from a butter knife. Alternatively, you can slightly heat the jars in warm water to loosen the wax.
  2. Clean the jars thoroughly: After removing the wax, make sure to get rid of any residue. Remove old wick holders with a bit of elbow grease and wash the jars with warm, soapy water. Rinse and dry them completely before moving on to the next step.
Melting the Wax

With your jars prepped and ready, it’s time to melt the wax.

  1. Set up a double boiler: If you don’t have a double boiler, you can make one by placing a heat-safe bowl over a pot of simmering water. This indirect heat method prevents the wax from burning.
  2. Monitor the temperature: Use a thermometer to keep an eye on the wax temperature. Ideally, it should stay between 160°F and 180°F (70°C to 82°C). Overheating the wax can cause it to discolor or even catch fire.
  3. Combine different waxes: If you’re using wax from various candles, mix them well to create a uniform consistency. This is also the time to add any essential oils if you want to enhance or blend scents.
Adding New Wicks

While your wax is melting, let’s prepare the new wicks.

  1. Choose the right wick size: Make sure the wick is appropriate for the size of your new candle container. A wick that’s too thin won’t burn properly, and one that’s too thick could create excessive smoke.
  2. Secure the wick: Place the wick in the center of your container and use a wick holder or a pencil to keep it upright and in place. This ensures that the wick stays straight when you pour in the hot wax.
Pouring the Wax

With your wicks in place and wax melted, it’s time to pour.

  1. Ensure the right pouring temperature: Before pouring, let the wax cool slightly to around 140°F (60°C). This helps avoid air bubbles and achieves a smoother surface.
  2. Pour the wax: Slowly pour the melted wax into the prepared containers. Be careful to pour gently to minimize bubbles. If you’re adding essential oils, mix them in right before pouring.
Setting and Finishing the Candles

Now, let your candles set and get ready for the finishing touches.

  1. Allow the candles to set: Place the candles in a cool, dry area where they can set undisturbed. This process usually takes several hours, but it’s best to leave them overnight.
  2. Trim the wick: Once the candles are fully set, trim the wick to about 1/4 inch (0.6 cm) above the wax surface. This helps ensure a clean, even burn.
  3. Final touches: Clean any spilled wax from the containers with a warm cloth. If you’re feeling creative, decorate the jars with labels, ribbons, or paint for a personalized touch.
Enjoying and Gift-Giving

Your upcycled candles are ready to shine!

  1. Burn safely: Always burn your candles in a safe location, away from flammable objects and drafts. Never leave a burning candle unattended.
  2. Gift ideas: Homemade candles make wonderful, thoughtful gifts. Consider customizing them with unique scents or personalized jar decorations for friends and family.
  3. Share your creations: Encourage others to join the upcycling movement by sharing your candle-making journey. Post photos, share tips, and inspire others to get creative with their leftovers.

Upcycling old scented candle jars into new candles is not just a rewarding and eco-friendly project; it’s a journey of creativity and sustainability. By repurposing leftover wax and jars, you contribute to reducing waste and creating something uniquely yours. Imagine the satisfaction of lighting a candle you’ve crafted with your own hands, knowing you’ve given new life to what might have been discarded. It’s a fulfilling way to combine mindfulness with artistry, making it an ideal activity for those who value both the environment and their personal touch.
