Cleaning out the container

Cleaning out a candle container is a great way to recycle and reuse old candle jars. It can be a simple process, but it does require some care and attention.

Firstly, you will need to remove any remaining wax from the container. One way to do this is to melt the wax. You can use the "warming" setting on a stovetop, an oven, or a kettle to melt the excess wax, and then pour it out. Boiling water can also be used to melt the wax, and some people prefer this method as it helps to clean the jar. When pouring out the wax, it is important to use a sink strainer to catch the wax, as it can clog your drain. You can save the wax in a bag to be reused later, or discard it.

Once the majority of the wax has been removed, you will need to clean out any remaining residue. Hot, soapy water can be used to clean the jar, and a paper towel can be useful to wipe away any wax in corners. Ensure the jar is dried thoroughly before reusing it.

If you are planning to reuse the jar for a new candle, it is important to clean it well, as any remaining wax could impact the burning of your new candle. You can use a butter knife to get into any corners, and ensure all wax is removed.

Some people choose to repurpose their old candle containers for other uses, such as decorative planters, cotton ball holders, or cocktail glasses. If you are repurposing the jar, you may not need to clean it as thoroughly, but it is still important to remove any wax residue to ensure the jar is safe and hygienic for its new use.

Choosing the right wax

When choosing the right wax for refilling a candle container, there are several factors to consider. Firstly, the type of candle wax you select will depend on the style of candle you want to create. For refillable container candles, the wax should adhere well to the container, have good scent retention, and provide an even burn. Here are some of the most common types of wax for container candles:

Paraffin Wax

Paraffin wax is one of the most popular choices for candle-making due to its affordability, versatility, and excellent scent retention. It has a relatively low melting point, which allows for consistent and even burning. Paraffin wax is suitable for various candle types, including container candles, pillar candles, and votive candles. It also holds colour well, making it a good option for brightly coloured candles. However, paraffin wax is derived from petroleum, which may be a concern for those seeking more natural and eco-friendly alternatives.

Soy Wax

Soy wax has gained popularity for candle-making due to its natural, renewable, and eco-friendly properties. Derived from soybeans, soy wax is non-toxic, biodegradable, and free from toxins, making it a safer option for those with allergies. It has a lower melting point than paraffin wax, making it ideal for container candles as it provides a longer burn time and an even burn. Soy wax is also known for its great scent retention and minimal soot production, resulting in a cleaner burn. However, it has a flatter, matte finish compared to the smoother appearance of paraffin wax.

Coconut Wax

Coconut wax is a vegan and eco-friendly alternative for container candles. It is often used in blends rather than as a pure wax. Coconut wax is known for its excellent fragrance retention and clean-burning properties, resulting in minimal soot production. It is considered a high-end wax, often associated with luxury candle-making.

Beeswax

Beeswax is one of the oldest candle-making materials and is prized for its natural, earthy qualities. As a by-product of honey production, beeswax has a unique natural honey scent. It burns slowly and cleanly, producing little to no smoke, making it an excellent choice for long-lasting candles. Beeswax is one of the priciest options for candle-making wax, but its eco-friendly and clean-burning properties make it a worthwhile investment for those concerned about sustainability.

When choosing the right wax for refilling a candle container, consider the specific characteristics of each type of wax and select the one that best aligns with your desired outcome, whether it's scent retention, burn time, eco-friendliness, or aesthetic appeal.

Preparing the wick

When preparing your wick, you should first select the appropriate size. The size of the wick will depend on the size of your candle container. For a small container, one cotton string wick should be sufficient, while a larger container may require a braided wick made from three strings. The wick should be cut to a length that is slightly taller than the candle container, with the recommended height ranging from 1 inch to 3 inches longer than the height of the container. This ensures that the wick can draw enough wax upwards to fuel the flame.

The type of wax you are using and the width of your container will also influence the size of the wick. A thicker wick is suitable for harder waxes like beeswax, while softer waxes like soy wax and paraffin wax may require a thinner wick. If you are using multiple wicks, they should be spaced safely apart, with a minimum distance of 1.5 inches from the edge of the container.

You can also choose from a variety of wick materials, such as cotton, linen, hemp, jute, or wood. Cotton wicks can be created by twisting or braiding cotton string, and they may be coated in wax to give them structure and make them easier to light. Wooden wicks, such as balsa wood, create a crackling sound when they burn and pair well with woodsy scents.

Once you have selected and prepared your wick, you can attach it to your candle container. Peel-and-stick wicks are easy to place by lowering them into the centre of the vessel. Alternatively, you can glue the wick to the bottom of the container or use a metal wick sustainer tab with wax to secure it in place. Ensure that the wick is centred and straight to optimise its combustion and avoid wasting wax.

Adding fragrance

When adding fragrance to your candle, you can use essential oils or fragrance oils. It is important to note that fragrance oils should be labelled as "candle fragrance oil" to ensure they will bind with the wax. Avoid using other types of fragrances, such as soap fragrance, as these will not mix well with the wax.

To calculate the amount of fragrance oil needed, you can follow these steps:

  • First, divide the total weight of scented wax by 110% (10% is the amount of fragrance you will be adding).
  • Then, subtract that number from the total weight of wax to determine the exact amount of fragrance oil required.

For example, if you are making an 8 oz candle, you will need 154 g of scented wax. Dividing 154 by 1.1 gives approximately 140, so you will need to add 14 g of fragrance oil.

Once you have measured out the required amount of fragrance oil, add it to a small dish. Then, add your unscented wax to a measuring cup and stir in the fragrance oil with a wooden chopstick for 3-5 minutes. It is important to stir for the full amount of time to ensure the fragrance oil binds properly with the wax.

If you wish to add colour to your candle, you can add a small amount of candle dye at this stage. Start with a few drops or flakes, as this will be enough to create a light tint. You can always add more to darken the colour if desired.

After your fragrance oil and wax are fully combined, you can slowly pour the scented wax into your clean vessel.

Pouring and setting

Once your candle container is cleaned and ready, it's time for the pouring and setting process. This involves melting wax, adding scents, and pouring the wax into the container. Here's a step-by-step guide:

Melting the Wax

First, you'll need to melt your wax. You can do this using a double boiler on the stovetop or in the oven. If using a stovetop, place a pot of water on to boil, then place a heat-safe container with your wax flakes or pastilles inside the pot to melt the wax. Alternatively, preheat your oven to 200°F, line a baking sheet with aluminium foil or parchment paper, and place your jars with wax pastilles on the sheet. Allow the wax to melt in the oven for 45-60 minutes.

Adding Scents and Colours

If you're using essential oils or fragrance oils, add them to the melted wax now. For an 8-ounce candle, 30-40 drops of essential oil is recommended. You can also add decorative items like dried flowers, wood chips, or herbs in small amounts, being careful not to add too much that it interferes with the wick.

Pouring the Wax

Now it's time to pour the wax into your prepared candle container. Centre your wick in the container and carefully pour the melted wax into it. You can use a small, flexible plastic cup to make pouring easier and reduce spills.

Setting and Curing

Allow the candle to cool and set completely before cutting the wick to size. This curing process can take about 24 hours. If your candle develops a dip around the wick, melt a small amount of additional wax to top it off and create a smooth surface.

Refilling candle containers is a great way to be resourceful and enjoy your favourite candles again and again. With these steps, you can create beautiful, personalised candles with your choice of scents and decorative touches.

Frequently asked questions

To clean your candle container, first, pour out any old wax into a small carton or plastic container. Then, use a paper towel to clean out any remaining wax from the inside of the vessel before it hardens again. You can use a butter knife to get into any corners. Clean out any remaining soot or wax residue with hot, soapy water and then dry your vessel thoroughly.

You will need a heat-safe measuring cup, hot glue gun, soy wax, cotton wick, fragrance oil, and a stove or kettle. You can also use essential oils, dried flowers, wood, herbs, stones, or gemstones for decorative purposes.

First, use a hot glue gun to add glue to the bottom of the wick and place it in the centre of the clean vessel. Then, bring water to a boil in a small pot and place the measuring cup with wax in the water. Wait 5-10 minutes or until the wax is liquefied. Pour the melted wax into your candle container and allow it to cool and cure completely before lighting.

The amount of wax you need depends on the size of your candle container. For example, an 8 oz. candle needs 154 g of scented wax, a 6 oz. candle needs 115 g, and a 4 oz. candle needs 75 g.
