There are various methods to cool down candles, including letting them cool at room temperature, using a water bath, or placing them in the fridge or freezer. While cooling candles in the fridge can speed up the process, it can also lead to cracking and other issues such as weakening the scent. To avoid these problems, it is recommended to let candles cool down slowly at room temperature. The time it takes for a candle to cool down in the fridge depends on the type of mould and the thickness of the candle. Metal moulds can be placed in the fridge for an hour, while plastic or polycarbonate moulds may only need 20 minutes. Thin candles typically require less time in the freezer than thicker pillar candles.

What You'll Learn
Metal moulds can be put in the fridge for an hour
One alternative method involves filling a container with cool water, ensuring that the water temperature does not fall below 15° Celsius (59° Fahrenheit). The candle mould is then submerged in the water bath and weighed down with a heavy object to keep it steady. This technique allows the candle to cool gradually and evenly, reducing the risk of cracking.
Another approach is to allow the candle to cool at room temperature before placing it in the refrigerator. This method balances the need for accelerated cooling and the risk of cracking by allowing the candle to initially harden at room temperature.
It is worth noting that some candle makers recommend against using the refrigerator for cooling, as rapid cooling can cause the glass to crack or shatter, create wet spots or sinkholes, and weaken the scent of the candle. Instead, they suggest letting the candle cool down as slowly as possible to avoid these potential issues.
In conclusion, metal moulds can be placed in the fridge for an hour to accelerate the cooling process, but this technique should be approached with caution. It is essential to consider the potential risks, such as cracking, and to explore alternative methods that may better suit the specific candle-making project.

Plastic moulds need only 20 minutes in the fridge
When it comes to candle-making, the cooling process is crucial, and it's important to do it right to avoid any cracks or shrinkage in your final product. While some candle makers recommend allowing candles to cool at room temperature, others suggest using a refrigerator or freezer to speed up the process, especially when it comes to getting the candle out of its mould.
If you're using plastic moulds, the good news is that they typically require less cooling time than metal moulds. On average, plastic moulds only need about 20 minutes in the fridge to cool down effectively. This shorter cooling time is an advantage, as it means you can produce candles more quickly and efficiently, without compromising their quality.
To get the best results with plastic moulds and a 20-minute fridge cool down, there are a few key steps to follow. Firstly, ensure your candle has set up enough so that it won't spill when you move it to the fridge. This initial setting can be done at room temperature, and it's a crucial step to avoid any mess or mishaps. Once your candle has reached this stage, you can carefully transfer it to the fridge.
During the cooling process in the fridge, it's important to maintain a stable temperature. Aim for a temperature no cooler than 15° Celsius (59° Fahrenheit). If the temperature drops too low, there is a risk of your candle cracking. To avoid this, you can use a water bath by filling a container wider and taller than your mould about three-quarters full of cool water. This helps regulate the temperature and prevents drastic temperature changes that could damage your candle.
After 20 minutes in the fridge, your plastic mould should be sufficiently cooled. Remove the mould from the fridge and carefully take your candle out of the mould. If you've used the water bath method, remember to remove the mould from the water before attempting to remove the candle. Once your candle is free from the mould, you can continue with any additional steps, such as trimming the wick or adding any finishing touches.

The ideal water bath temperature is 15° Celsius
While placing candles in the fridge can speed up the cooling process, it can also lead to several issues. Candles may crack or shatter, the wax may shrink and create wet spots or sinkholes, and the scent throw may be weakened. To avoid these issues, it is recommended to let candles cool down slowly at room temperature. However, if you wish to use the fridge to speed up the process, it is important to note that the ideal water bath temperature should not be cooler than 15° Celsius (59° Fahrenheit).
The process of creating candles involves pouring wax into moulds and allowing them to cool and set. The ideal temperature for pouring wax is crucial to ensure the candle sets properly. While some candle makers recommend a water bath to cool the moulds, others suggest that this method can be risky as it can cool the wax too quickly, leading to cracking or other issues. Thus, it is generally recommended to let the candles cool at room temperature for a while before considering a water bath or refrigeration.
The ideal water bath temperature of 15° Celsius (59° Fahrenheit) is important to maintain as it balances the need to cool the candles without causing thermal shock, which could lead to cracking or other issues. At this temperature, the wax will cool down at a controlled rate, allowing it to solidify gradually without damaging the candle. A water bath at this temperature can be used to cool the moulds after the candles have been poured and allowed to rest for a short period at room temperature.
To achieve the ideal water bath temperature of 15° Celsius, it is necessary to monitor the temperature with a thermometer. This ensures that the water is not too cold, which could lead to rapid cooling and potential damage to the candles. By using a thermometer, candle makers can make adjustments by adding small amounts of boiling water to increase the temperature if needed. This attention to temperature control is crucial to avoid the negative consequences of rapid cooling, such as cracking, shrinkage, and weakened scent throw.
Additionally, it is worth noting that the type of mould can also impact the cooling process. Metal moulds, for example, can be placed in the fridge for an hour, while plastic or polycarbonate moulds may only need 20 minutes to cool down effectively. Understanding these nuances can help candle makers adjust their cooling techniques accordingly. Overall, while the fridge can be used to speed up the cooling process, it should be done with caution and a thorough understanding of the ideal water bath temperature and other factors influencing the cooling process.

Avoid rapid cooling to prevent candle cracks
While it is tempting to put your candles in the fridge or freezer to speed up the cooling process, this can often lead to candle cracks. The wax cools down too quickly, which can cause the surface of the candle to crack. This is especially true if the room is too cold, or humid, or if the candle glasses themselves are cold.
To avoid this, candles should be allowed to cool down slowly and at a steady room temperature. The ideal temperature for a room is between 18°C and 20°C, but it should not exceed 25°C. If the room is too hot, the candles may not set properly, but if it is too cold, the wax will cool too quickly and crack.
There are other ways to speed up the cooling process without risking cracks. One way is to use a water bath. Fill a container three-quarters full of water at a temperature no cooler than 15°C. Weigh down the candle mould with something heavy and steady, like a book, and then place it in the water. This will help the candle to cool without risking cracks.
Another way to speed up the process is to pre-heat your vessels before pouring in the wax. This will lessen the amount of shrinkage during the cooling process. You can also prick the candle around the wick with a wicking needle, then refill the candle with heated wax.
Finally, to avoid cracks, you should also avoid stirring the wax too much or too vigorously, as this can create air bubbles that get trapped during the cooling process. These air bubbles can cause the candle to crack. Instead, stir slowly and smoothly, and tap out any air bubbles that do form before pouring.

Pillar candles need 6-8 hours in the freezer
While putting candles in the fridge can speed up the cooling process, it can cause the glass to crack or shatter, make the wax shrink, and create wet spots or sinkholes. It can even weaken the scent throw. Therefore, it is recommended to let your candle cool down slowly at room temperature. However, if you are making a pillar candle and need help getting it out of the mould, you can place it in the fridge or freezer.
Pillar candles are thicker than thin candles and, therefore, require more time in the freezer. Thin candles will only need an hour or less in the freezer, whereas pillar candles need 6-8 hours. If you have more than one candle, test just one in the freezer before adding the others, as some candles may crack when frozen.
To cool your candles, first allow them to set for 30 minutes to an hour at room temperature. Then, place the candle in a water bath by filling a container with cool water. Ensure the water is no colder than 15° Celsius (59° Fahrenheit). Leave the candle in the water bath for an hour or so, then remove it.
If you are in a hurry and need to speed up the cooling process, you can place your candle in the fridge for a day or two. However, this may cause the issues mentioned above, so proceed with caution.
Remember, it is important to monitor the temperature throughout the candle-making process with a thermometer. This will help prevent scorching the wax and ensure you are adding fragrance and pouring the wax at the recommended temperatures.
