What You'll Learn

Removing wax from candle jars
Freezing
Place the candle jar in the freezer for a few hours or overnight. The wax will freeze and peel off the sides of the jar. After removing the jar from the freezer, use a knife to pop the frozen wax out of the container.
Boiling Water
Fill the candle jar halfway with boiling water. The wax will rise to the surface on its own. Let the water cool down, then remove the wax. You can also use a hairdryer on a hot setting to melt the wax.
Oven
Place the candle jar upside down on a tray in an oven preheated to 250°F (120°C). When the wax has melted, pour it out into a disposable container and wipe the jar clean with a paper towel.
Double Boiler
Place the candle jar in a bowl set over a pot of simmering water. Alternatively, place the candle in a separate pot and slowly pour boiling water around it, ensuring the water doesn't go into the jar. Once the wax has melted, pour it into a disposable container and wipe the jar clean.
After removing the wax, you can wash the jar with soap and water to remove any remaining residue.

Repurposing candle jars for food storage
Glass candle jars can be reused for food storage, but it is important to ensure that they are thoroughly cleaned and any wax residue is removed before doing so. Here are some ways to repurpose candle jars for food storage:
Removing Wax Residue
Before reusing candle jars for food storage, it is crucial to remove any leftover wax. One way to do this is by freezing the jar, which will harden the wax and make it easier to pop out using a butter knife. Alternatively, you can melt the wax by placing the jar in the oven at a temperature below 200°F or using a double boiler method on the stovetop. Once the wax is melted, pour it into a disposable container and let it harden before discarding it. You can also use boiling water to melt the wax; simply pour it directly into the jar, leaving some space at the top, and wait for the wax to float to the top. After removing the wax, remember to clean the jar with soap and water to eliminate any residue.
Storing Dry Goods
Once your candle jars are clean and free of wax, you can use them for storing dry goods in your pantry or refrigerator. This is a great way to reduce your use of plastic bags when buying items like dry beans, grains, and other bulk goods at the supermarket.
Prepping Food
You can also use the jars to prep food like salads and overnight oats for consumption later in the week. Just remember to keep any liquid ingredients, like salad dressing, at the bottom of the jar to prevent sogginess.
Regrowing Food Scraps
Candle jars without lids can be used for regrowing food scraps. Place scraps of vegetables like green onions, celery, leafy greens, or bean sprouts in water and give them a little sunlight. You'll be able to see the roots growing, and you can snip them off and add them to your meals.
Fermentation
Wide-mouth candle jars without lids can be used for food fermentation, provided the glass is food-safe. Fermented foods like kimchi, sauerkraut, and fire cider can be stored in these jars. Just remember to leave some extra space at the top of the jar to allow for expansion during the fermentation process.
Short-Term Storage
While some people have concerns about the food safety of candle jars, especially when it comes to long-term storage, many agree that thoroughly cleaned and sterilized jars can be used for short-term food storage. This could include storing items for a lunch box or overnight oats that will be consumed within a day or two.
By repurposing candle jars for food storage, you can reduce waste, minimize your environmental impact, and create stylish and functional storage solutions for your home.

Using candle jars for regrowing food scraps
Glass jars are a great way to regrow food scraps and reduce food waste. Before using candle jars for this purpose, it is important to remove the wax and clean the jars thoroughly. This can be done by freezing the jars, using a double boiler, or pouring boiling water directly into the jars.
Once the candle jars are cleaned, they can be used to regrow various food scraps. Green onions are one of the easiest foods to regrow from scraps. Save the white ends of the green onions and put them in a jar of filtered water. Place the jar on a sunny windowsill and change the water every day or so. In about a week, the green onions will have regrown.
Other foods that can be regrown in candle jars include celery, romaine lettuce, garlic, fennel, leeks, and carrots. For most of these foods, place the ends or tops of the scraps in about an inch of water and set them in partial sunshine. Change the water daily and, once roots have formed, transplant them into soil.
For those who enjoy gardening, candle jars can also be used for food fermentation. Kimchis, sauerkraut, and fire cider are all great options to try. Just make sure that the glass is food-safe and provide extra space at the top of the jar for food to expand during fermentation.
By reusing candle jars for regrowing food scraps, not only are you reducing waste, but you're also contributing to a more sustainable lifestyle.

Making new candles from leftover wax
Step 1: Remove Leftover Wax
To begin, you'll need to remove the leftover wax from your old candles. This can be done by placing the candles in the freezer for a few hours until the wax is frozen. Then, use a butter knife or a similar tool to pop the wax out of the container. Alternatively, you can try the boiling water method. Place the candle on a heat-safe surface and pour boiling water directly into the jar, leaving some space at the top. The wax will float to the top as it melts. Wait for the water to cool, then remove the wax.
Step 2: Melt the Wax
Once you have collected the leftover wax, it's time to melt it down. Create a double boiler by placing a small pot inside a larger pot filled with water. Bring the water to a simmer and place your leftover wax in the small pot to melt. You can also use a microwave or a heat gun to melt the wax, but be careful not to overheat it.
Step 3: Prepare the Wick
While your wax is melting, prepare your wick by cutting a piece of wicking that is about 2 inches taller than your chosen candle container. You can find wicking at craft stores. Knot one end of the wicking and thread it through a wick tab, which can also be purchased from craft stores.
Step 4: Add Colour and Scent (Optional)
This step is optional, but if you want to experiment with colour and scent, now is the time to add them. Use small amounts of dye and essential oils, building up the quantities gradually. Too much dye or oil can affect the candle's burn, so it's best to start with less and adjust as needed.
Step 5: Pour the Wax
Once your wax is melted and any additives are incorporated, it's time to pour it into your chosen container. Place the wick in the centre of the container, securing it with the wick tab, and pour the melted wax around it. Stop pouring when the wax level is about half an inch below the rim of the container.
Step 6: Let it Set
Allow the candle to set for at least 24 hours before lighting it. Trim the wick to the desired length, and enjoy your new candle!
Making candles from leftover wax is a creative and sustainable way to reduce waste and enjoy your favourite scents for longer. With these simple steps, you can create unique, personalised candles that are both earth-friendly and aesthetically pleasing.

Decorating candle jars for home decor
There are many ways to decorate candle jars for home decor. Before decorating your candle jar, it is important to remove the remaining wax and clean the jar. This can be done by freezing the jar and then popping out the wax, or by melting the wax using a hairdryer, hot water, or a double boiler. Once the wax is removed, the jar can be cleaned with soap and water, and any remaining adhesive can be removed with a mixture of oil and baking soda, or with isopropyl alcohol or Goo Gone.
After the jar is clean, it can be decorated in a variety of ways. One option is to paint the jar with heat-resistant paint. This can add a pop of color to your home decor and can be especially effective if you use a bright or bold color. Another option is to add natural elements to the jar, such as pine cones, pine needles, or dried flowers. This can add a subtle scent to the jar and create a rustic or natural aesthetic.
Candle jars can also be decorated by filling them with items. For example, you could use the jar as a flower vase or a storage container for items such as makeup brushes, cotton balls, or office supplies. You could also fill the jar with water and use it to regrow food scraps such as green onions, celery, leafy vegetables, or bean sprouts. Alternatively, you could fill the jar with dry ingredients such as beans, grains, or other bulk items purchased from the supermarket.
For a more functional decoration, you could use the jar as a drinking glass or tumbler, or as a container for overnight oats or salads. If you have multiple candle jars, you could also use them as a set of snack bowls or as storage for toiletries or other small items. With a little creativity, the possibilities for decorating and repurposing candle jars are endless!
