Candles are often left to cool at room temperature, but in colder environments, they can solidify too quickly, causing issues like bubbles or sinking. To avoid this, candle makers can preheat the jars in an oven, wrap them in tin foil, and then pour in the wax once the temperature has dropped to around 65-70°C. This technique prevents the candles from pulling away, getting bubbles, or sinking.

Heat jars in the oven before pouring wax
Heating your candle jars in the oven before pouring wax is a great way to ensure your candles set smoothly. This technique is especially useful during the colder months, as the glass candle jars can get extremely cold, causing the wax to cool too quickly and unevenly, resulting in an uneven surface or "frosting".
To heat your jars in the oven, start by preheating your oven to a low temperature, ideally between 120-160°F (approximately 49-71°C). Place your glass jars on a cookie sheet or directly on the oven rack. If using a cookie sheet, it is recommended to place the jars on a tray of hot (not boiling) water to help regulate the temperature and prevent the glass from shattering due to sudden temperature changes.
While the jars are warming in the oven, you can melt your wax. It is important that your wax and jars are as close in temperature as possible when you pour, so try to time this step accordingly. Remove the jars from the oven when they are warm, using a pot holder or oven mitts to protect your hands.
By warming your candle jars, you reduce the temperature difference between the wax and the jars, minimising the risk of wet spots and air bubbles forming. This technique helps to slow down the cooling process, improving adhesion and resulting in a smoother candle surface.

Let candles cool inside the oven
Leaving candles in the oven is a great way to cool them faster. Here is a step-by-step guide to making candles in the oven, which also applies to letting them cool:
Firstly, preheat your oven to 200 degrees Fahrenheit. Place your candles on a baking sheet, ensuring they are in jars or another suitable container. It is important to note that the candles should be in a glass jar or container to avoid any potential fire hazards or wax spills in your oven.
Once the oven is preheated, put the baking sheet with the candles inside and keep them there until the wax has mostly melted. If you are making candles, this is when you would add more wax flakes and essential oils, but if you are simply cooling the candles, you can skip this step and let the wax melt completely.
After the wax has melted, remove the candles from the oven and let them cool and solidify. It is important to let the candles cool completely before handling them or lighting the wick. This method of cooling candles in the oven can help speed up the process, especially if your oven tends to stay warm even when it's turned off.
Additionally, if you are reshaping the remaining wax of a candle, you can put it in the oven to liquefy, then drop in a fresh wick and let it cool, solidifying the wax around the new wick. This method can also help to clean the candle by allowing the ashy sediment to sink to the bottom.

Preheat jars wrapped in tin foil
Warming candle jars before pouring the wax is a commonly recommended technique to cool candles faster and achieve a smooth finish. This is because the temperature difference between the wax and the jar is reduced, minimising the shock when the candle sets.
To preheat jars wrapped in tin foil, start by wrapping the jars in a layer of tin foil. This will help to distribute heat evenly around the jars and protect them from direct heat. Set your oven to a low temperature, ideally between 70-75 degrees Celsius. Place the wrapped jars in the oven and let them warm up for a few minutes. If you don't have an oven, you can also use a heat gun to heat the jars. Alternatively, place the wrapped jars in a tray and pour hot (not boiling) water into the tray, ensuring the water level is high enough to cover the jars.
It is important to ensure that the jars are not too hot when you remove them from the heat source. Use oven mitts or tongs to handle the jars, and test the temperature with a laser thermometer gun if possible. The jars should be warm to the touch but not scalding.
Once the jars are preheated, you can start pouring your wax. This technique will help reduce frosting and create a smooth finish on your candles. It is especially useful when making candles in colder weather, as it helps to control the cooling process and prevent issues such as wet spots, sinkholes, and cracking around the wick.
By preheating the jars, you are providing a warm environment for the wax to set, which slows down the cooling period. This slower cooling contributes to better adhesion and a smoother surface on your candles. It is important to note that while this technique is generally safe, you should always exercise caution when working with hot wax and heated jars to avoid any accidents or injuries.

Pour wax when the glass is hot
One effective method to cool candles faster is to preheat the glass jars in the oven before pouring the wax. This technique helps prevent issues such as the wax pulling away, forming bubbles, or sinking. Here are some detailed steps and tips to guide you through the process:
Firstly, it is important to prepare your workspace and gather the necessary equipment. Ensure you have a suitable oven that can be adjusted to the desired temperature settings. While some recommend heating the oven to its lowest setting, typically around 170°F (76°C), others suggest a lower temperature of 65°C. Adjust the temperature according to your oven's capabilities and your personal preference.
Once you've set the temperature, carefully place the glass jars inside the oven. You can wrap them in tin foil for added protection. Allow the jars to heat up thoroughly before moving on to the next step.
Now, you can start preparing your wax. While the glass is still hot, take it out of the oven and get ready to pour the wax. It is important to work quickly during this step to maintain the temperature of the glass. Place the hot glass on a rack, ensuring that the bottom of the glass is not directly on the counter. This helps distribute the heat evenly and prevents direct contact with a potentially cool surface.
Proceed to pour the wax into the hot glass jars. After pouring, you can turn off the oven and place the filled glass jars back inside. Leaving them to cool inside the oven helps maintain a consistent temperature and prevents rapid cooling, which can cause imperfections in the wax.
By following these steps, you can effectively cool your candles faster and achieve desirable results. Remember to take the necessary safety precautions when working with hot glass and heated wax. Always use oven mitts or heat-resistant gloves when handling hot items, and ensure your workspace is well-ventilated. With practice and experimentation, you'll be able to refine your technique and create beautiful, smooth-topped candles efficiently.

Maintain a temperature of 65°C
Maintaining a temperature of 65°C is essential when working with beeswax, which has a melting point of 62-65°C. This temperature range is crucial for ensuring that the beeswax is in a molten state and can be poured and shaped into candles. Here are some detailed instructions to achieve and maintain this temperature:
First, invest in a good thermometer to accurately measure the temperature of your wax. Place your beeswax in a double boiler or a melting pot on a stove. Turn on the heat to medium and stir the wax occasionally to ensure even melting. Monitor the temperature closely with your thermometer.
Once the wax reaches 62°C, adjust your stove to a lower heat setting to maintain a steady temperature of 65°C. You may need to fine-tune the heat setting to find the perfect balance that keeps the wax at this desired temperature without exceeding it. At 65°C, your beeswax will be in a liquid state, ready for pouring into candle moulds or containers.
Maintain this temperature throughout the pouring and curing process. If you are working in a cool environment, you may need to adjust the room temperature to prevent the wax from solidifying too quickly. Ideally, keep the room temperature at around 21°C (70°F) to prevent drastic temperature changes that could affect your candles' quality.
Finally, maintain a consistent temperature during the curing process. Beeswax candles typically require two days of curing time at a constant temperature of 65°C. This curing process ensures that your candles harden properly and become suitable for burning.
By carefully controlling the temperature at 65°C, you can create high-quality beeswax candles with a smooth finish and stable structure.
