Choosing a glass vessel

The shape of the vessel is another important factor. Choose a glass container with a wide opening at the top, which will ensure a long and even burn. Avoid jars with narrow openings as they may cause the flame to extinguish prematurely. Additionally, check for any small cracks in the glass, as these can compromise the safety and longevity of your candle.

You can repurpose various glass items, such as antique serving dishes, teacups, mugs, or chalices, into beautiful candles. If you're using a vessel that previously held a candle, remove any remaining wax and wash the container thoroughly with warm, soapy water. You can use rubbing alcohol to get rid of any sticker residue.

When selecting a glass vessel, it's essential to use heat-safe containers. You can find these at craft stores or opt for candle refill kits that provide you with the necessary materials, including the glassware. Some companies even offer refill services, allowing you to send in your chosen vessel for a professional refill.

With these guidelines in mind, you can choose a glass vessel that suits your style and preferences while ensuring a safe and enjoyable candle-making experience.

Melting wax

Choosing the Right Wax

The first step is to select the type of wax you want to use. Common options include soy wax, paraffin wax, beeswax, and gel wax. Each type of wax has a different melting point, so it's important to choose the right wax for your project. Soy wax, for example, melts at a temperature range of 49-82°C, while paraffin wax has a slightly lower melting point of 46-68°C. Beeswax typically melts between 62-65°C, and gel wax has a higher melting point of 82°C.

Double Boiler Method

One popular method for melting wax is the double boiler technique. This method is suitable for candles in glass jars. Simply place the jar of wax in a larger container of water and heat it until the wax liquifies. This method may take longer than others but ensures a steady and controlled melting process.

Microwave Method

If you're looking for a faster way to melt wax, consider using a microwave. This method is quicker than the double boiler but requires careful monitoring to avoid overheating. Make sure to use a microwave-safe container, such as a ceramic or glass dish, and always check for relevant labels. Pour your wax into the container and heat it in one-minute intervals until it reaches the desired temperature. For safety, do not exceed 80°C.

Safety and Preparation

When melting wax, it's important to take safety precautions. Wear protective gear, such as heat-resistant gloves and an apron, to avoid any spills or splashes. Always monitor the temperature to prevent overheating, and never leave melting wax unattended. Additionally, ensure your work area is well-ventilated to dissipate any fumes. Before pouring the wax, prepare your moulds or vessels by cleaning and drying them thoroughly. Check for any cracks or imperfections that may affect the final product.

Adding Colour and Fragrance

Once your wax has melted and reached the desired temperature, you can add colour and fragrance. Typically, colour is added first, followed by fragrance oil. It is recommended to add colour at around 70°C, ensuring an even distribution. Fragrance oil can be added at a similar temperature, allowing you to create beautifully scented candles. Always follow the manufacturer's instructions for adding colour and fragrance to achieve the desired intensity and scent throw.

By following these detailed steps for melting wax, you'll be well on your way to successfully refilling your glass pillar candles with a fresh, customised look and aroma.

Pouring wax into the vessel

When pouring wax into the vessel, there are a few important things to keep in mind. Firstly, ensure that the wax has been properly melted into a golden liquid before pouring. This can be done using a microwave if you are using a microwavable candle refill kit, or by using a double boiler or candle warmer. Be very careful when handling melted wax, as it will be extremely hot. If children are involved in the project, an adult should handle this step.

Next, check your glass vessel for any small cracks that may compromise the life and safety of the candle. If there is any wax remaining at the bottom of the vessel, scoop it out with a spoon and discard it. Then, hand wash the vessel thoroughly with warm, soapy water and dry it well. If there is any sticker residue at the bottom, you can use rubbing alcohol to remove it.

Once your vessel is clean and dry, you are ready to pour the wax. Pour the wax slowly and carefully into the vessel, leaving 1/2" to 1" of space at the top for optimum candle burning. Use a wooden wick holder to stabilise the wick by stringing the top of the wick through the centre hole of the stick, allowing the stick to rest on the edge of the vessel as the wax cools. Remember to work quickly, as the wax will begin to solidify once it is no longer heated.

If you are using soy wax, keep in mind that it is water-soluble, so any drips can be easily cleaned up with warm soapy water. With these steps, you can successfully pour wax into your chosen vessel and create a unique, personalised candle.

Adding a wick

When refilling a glass pillar candle, adding a wick is one of the most important steps. Here is a detailed guide on how to do it:

Choosing the Right Wick

Before adding a wick to your glass pillar candle, it is crucial to select the appropriate type of wick. The choice of wick depends on various factors, such as the type of wax, fragrance, and dye used in your candle. The goal is to achieve a consistent flame size, minimise carbon deposits (blooming), maintain a moderate container temperature, and form a well-shaped wax pool without dripping.

Determining Wick Size

The size of the wick is also an important consideration. If the wick is too small (under-wicked), it may result in tunnelling, where the candle burns down the centre, leaving hard wax around the edges. This will reduce the burn time of your candle. On the other hand, if the wick is too large (over-wicked), it will produce an excessively large flame that flickers and causes the container to become very hot, potentially leading to cracking.

Preparing the Wick

Once you have selected the appropriate wick, you may need to add a wick sustainer at the bottom. To do this, thread the wick through the hole of the sustainer and use pliers to crimp and secure the tab to the wick. Store your finished wicks in a cool, dry place.

Inserting the Wick

When your wax has been melted and poured into your glass vessel, it's time to insert the wick. Leave about 1/2" to 1" of space at the top of the vessel for optimal burning. Use a wooden wick holder to stabilise the wick by threading the top of the wick through the centre hole of the holder. Let the holder rest on the edge of the vessel while the wax cools down.

Alternative Method: Using a Matchstick

If you encounter issues with a short or broken wick, there is a simple alternative method. Take a matchstick, break off the head, and carefully stab the match into the wax next to the wick. The matchstick will act as a new wick and should burn effectively.

Eco-friendly refill options

When choosing eco-friendly refill options, it is important to consider the type of wax used. Some of the most eco-friendly wax options include:

  • Coconut wax: This is considered one of the purest and most eco-friendly options. It is a natural, biodegradable wax with a high melting point, which makes it ideal for scented candles and provides a longer burn time. Coconut wax is also energy-efficient to produce and has a lower environmental impact compared to soy or palm waxes due to the lower water and pesticide requirements of coconut trees.
  • Rapeseed wax: Rapeseed wax is natural, vegan, renewable, and biodegradable. It is also known for distributing scent well, making it a good option for scented candles.
  • Beeswax: Beeswax is biodegradable and naturally cleans the air, but it is not vegan. It is produced by honeybees and supports biodiversity and pollination. Beeswax candles burn longer and cleaner than many other types, but their use depends on responsible beekeeping practices.
  • Soy wax: Soy wax is natural, vegan, renewable, and biodegradable. It is a popular eco-friendly option that is derived from soybeans, a renewable resource. It is also biodegradable and has low toxicity, making it a preferred choice for candle makers. However, there may be some concerns around the soybean industry's use of deforestation and pesticides.
