What You'll Learn
Use an oven to melt the wax
To fix a candle in a jar that has melted, you can melt the wax and reuse it. Here is a guide on how to do this using an oven:
Prepare the jar:
First, make sure you are using a heat-resistant glass jar that is designed for high temperatures and can withstand the heat needed to melt candle wax safely. Glass types like borosilicate glass are ideal as they are more durable and less prone to thermal shock. Place your glass jar on a baking tray lined with aluminum foil to catch any wax that might overflow. Remove any labels or stickers from the jar.
Preheat the oven:
Set your oven to a low temperature, ideally between 150°F and 170°F (65°C to 75°C). Higher temperatures may cause the glass to crack.
Melt the wax:
Place the tray with the jar in the oven and allow the wax to melt slowly and evenly without overheating the glass. This should take around 10 to 15 minutes.
Remove the jar:
Once the wax has melted, carefully remove the jar from the oven using oven mitts. The jar will be hot, so handle it with care.
Reuse or repurpose the wax:
You can now pour the melted wax into a mold or another container for reuse. You can make your own votives by following these steps: Cut a piece of wicking, available at craft stores, 2 inches taller than the votive holder. Knot one end and thread it through a wick tab. Tie the free end around a wooden skewer. Dip the wicking and tab into the melted wax to coat them. Remove, then press the tab to the bottom of the holder, and rest the skewer on the rim. Pour the melted wax into the votive holder, stopping 1/2 inch below the rim. Let it stand until it sets, about one hour. To even the well at the center, pour more wax into the center until it's a 1/4 inch below the rim.

Use a double boiler to melt wax
Melting candle wax with a double boiler is a safe and efficient method. This technique uses indirect heat to melt the wax, which is especially useful if your jar may not withstand direct heat. Here's a step-by-step guide on how to do it:
Firstly, set up your double boiler by filling a large pot with water and placing it on the stove. Ensure you don't fill it up too much, as you don't want the water to touch the bowl or pot you'll be placing inside. Bring the water to a simmer.
Next, place your wax in a smaller container, such as a pouring pitcher, clean coffee can, or a smaller saucepan. If you're using a jar, make sure it's made of heat-resistant glass. Place this smaller container with your wax inside the larger pot of simmering water.
Allow the steam from the boiling water to heat the bowl or pot with the wax. This will melt the wax inside. You can stir the wax occasionally to encourage melting, but be careful not to stir too aggressively, as this can introduce air into the blend, impacting the final candle quality.
Monitor the temperature of the wax with a thermometer. When the wax reaches around 185°F to 190°F (85°C to 88°C), it's ready to be removed from the heat. Use oven mitts or potholders when handling the hot containers.
Now, you can add colour and fragrance to your melted wax. Add 3 to 5 drops of liquid dye, ensuring it's oil-soluble. Stir the blend for about two minutes to ensure the dye is well-distributed. Then, add your measured amount of fragrance oil, typically around 185°F, but always check your wax supplier's instructions.
Finally, pour your wax blend into your chosen container at a steady rate. Try to avoid introducing too much air into the blend during this process.
Remember, once you've used a pan for melting wax, it shouldn't be used for preparing food. Also, be cautious when handling hot wax, and never leave the double boiler unattended.

Place the candle jar in the freezer
Placing the candle jar in the freezer is a simple and effective way to remove candle wax from the jar without melting it. This method utilises the unique properties of wax, which shrinks and hardens when exposed to cold temperatures.
To begin, simply place the entire candle jar in your freezer. Leave it there for several hours or until the wax is completely frozen. You can check if the wax is frozen by gently pushing down on it. If it moves under the pressure, it's frozen.
Once the wax is frozen, remove the jar from the freezer. You can now easily pop the wax out of the jar. If needed, use a butter knife to loosen the wax from the sides of the jar. Be careful not to scratch or damage the glass with the knife. The wax should come out in one piece, leaving the jar clean.
If there is any residual wax or wick left in the jar, you can use a butter knife to gently scrape it off. Alternatively, you can wash the jar with soap and water or even use baby oil to remove stubborn residue.
This method is a mess-free and straightforward way to remove candle wax from a jar without having to melt the wax. It is especially useful for candles made from wax with a low melting point, such as soy candles.

Use hot water to melt the wax
Using hot water to melt the wax in a candle jar is known as the double boiler method. This method is ideal for melting leftover candle wax. It is also useful for glass jars that may not withstand direct heat as well.
To set up the double boiler, fill a large pot with water and place it on a stove. Put the candle jar in a smaller pot or heatproof container, such as a glass bowl or pouring jug, and place it inside the larger pot. Turn on the stove and heat the water to a simmer. The steam generated between the two pans will gently melt the wax inside the glass jar.
Different types of wax have different melting points, ranging from 100 to 145 degrees Fahrenheit (or 37 to 63 degrees Celsius). Softer waxes, such as soy wax, can be melted with hot water that is not boiling. Keep in mind that the glass can become very hot, so handle it with oven mitts and be cautious to avoid breakage.
Once the wax has melted, carefully remove the jar from the heat source. You can then pour the melted wax into a mould or another container for reuse.

Choose the right jar for melting candles
When choosing a jar for melting candles, it is important to select a container that can withstand the heat created by the candle. Shattered glass, melted wax, and even fires can result from choosing the wrong jar. Here are some factors to consider when choosing the right jar for melting candles:
Heat Resistance
Glass quality and heat resistance are crucial factors when choosing a jar for melting candles. Regular glass jars, such as those used for jams, pickles, or sauces, may not be able to withstand the heat of melted candle wax. Look for jars made from heat-resistant glass, specifically designed for high temperatures. Glass types like borosilicate glass are ideal as they are more durable and less prone to thermal shock, which is when glass cracks due to sudden temperature changes.
Thickness
Thick glass candle jars offer excellent durability and better heat insulation. They can withstand prolonged use and are commonly used by premium candle brands. Frosted glass candle jars are another option that can handle moderate heat while also providing aesthetic appeal.
Reinforced Glass
Reinforced glass candle holders are specifically designed to withstand the melting process. They are thicker and treated to resist high heat without breaking. These candle holders are a great option for ensuring the safe melting of candles.
Shape
The shape of the jar is also an important consideration. The wick of a candle creates a circular melt pool that maintains the same diameter from the first burn to the last. Choosing a jar that is thinner at the top and wider at the bottom can lead to improper wicking and potentially cause the glass to shatter due to excessive heat. Select a jar with a consistent diameter to ensure proper wicking and heat distribution.
Sealant
If you choose a container made from a flammable material, such as wood, it is crucial to apply a thick coating of 100% waterproof sealer first. This will help prevent the container from catching fire. Similarly, containers made from materials like cement, terracotta, or clay should be properly sealed to prevent them from absorbing melted wax.
Alternative Options
While glass jars are commonly used for melting candles, there are alternative options available as well. Candle tins, for example, offer sleek designs, beautiful colours, and ease of labelling. They are a good option for beginner candle makers as they can hide imperfections. However, it is important to caution users about the heat absorbed by the tins to prevent burns.
