Curing is an important process in candle-making, especially for soy candles. It involves letting the fragrance oil and wax bind together and spread evenly before the wax sets. While it is possible to burn a soy candle after 24 hours of curing, it is recommended to wait for at least a week, and preferably two, to ensure a strong fragrance. During the curing process, it is advised to leave the candle uncovered to allow excess moisture and volatile compounds to escape, improving the quality of the candle. However, some people may choose to cover their candles for aesthetic or practical reasons, such as protecting them from dust. In such cases, it is crucial to ensure the candle is completely cooled before covering to prevent safety hazards caused by trapping heat.

What You'll Learn
The ideal curing time for soy candles is 1-2 weeks
Curing is a critical component of candle-making. It is the process of allowing the fragrance oil and wax to bind together and spread evenly before the wax sets. Soy candles need to be cured for longer than paraffin candles, but they do not have the same harmful effects.
The polymorphic nature of soy wax means that it will continue to harden over time, even after it has been poured into its mould. This means that candles will be harder a week after being poured than they were in the days immediately following. This can impact the size of the wick required to burn the candle effectively.
The length of curing time can also depend on the type of fragrance oil used. Heavier, stronger scents will be ready to burn more quickly than lighter, more delicate fragrances.
It is worth noting that the curing time for soy candles can vary depending on the batch of wax used, as the curing behaviour can change due to the variability in soybeans.

Curing allows the fragrance oil and wax to bind together
Curing is an essential process in candle-making, especially when it comes to soy candles. While it is possible to burn a soy candle after 24 hours of curing, this does not guarantee optimal results. The curing process allows the fragrance oil and wax to bind together, creating a semi-solid structure. This binding process is crucial for the candle's performance and fragrance throw.
The length of the curing process depends on various factors, including the type of wax and fragrance oil used. Soy wax, also known as "vegetable wax," is a natural wax that continues to harden over time due to its polymorphic nature. This means that soy candles will become harder a week after they are poured than they were a few days prior. Therefore, it is recommended to cure soy candles for at least one to two weeks to ensure the fragrance oil and wax have adequately bound together.
During the curing process, the fragrance oil, which is a liquid at room temperature, incorporates itself into the hardening wax. This binding allows the fragrance to be evenly distributed throughout the candle, resulting in a consistent and strong scent throw when the candle is burned. A longer curing time generally leads to a stronger fragrance, as it gives the fragrance oil more time to bind to the wax.
The curing time can also depend on the type of fragrance used. Heavier and more potent scents, such as bakery or gourmand fragrances, may be ready to burn in a shorter amount of time, while lighter and more delicate fragrances might take the full two weeks or even longer to reach their maximum potential. Additionally, the quality of soybeans used in soy wax can impact the curing behaviour, with different lots of wax exhibiting varying curing times.
While curing is necessary for all candles, the specific curing time can vary based on the type of wax. For example, paraffin candles typically require only 24 to 48 hours of curing before they are ready to burn, while natural waxes like soy and coconut benefit from a longer curing period of one to two weeks. Ultimately, the curing time for soy candles aims to maximise the fragrance release and ensure a consistent burn.

The curing time depends on the type of soy wax used
The curing time for soy candles depends on various factors, including the type of soy wax used, fragrance oil concentration, and environmental conditions such as temperature and humidity. Soy wax, being a natural product, generally requires longer curing times than paraffin wax. Pure soy wax candles are recommended to cure for at least two weeks, while a paraffin-soy blend may require less time, around one week.
The curing process allows the fragrance oils to bind effectively with the wax, enhancing the scent throw and performance. During this process, fragrance oils are incorporated into the wax, and the scent is allowed to fully develop and disperse more effectively. This results in a stronger, longer-lasting scent and improves both the cold and hot scent throw when the candle is burned.
The type of wax used is a crucial factor in determining the curing time. Soy wax, being a "natural wax," is derived from soybean oil, which is transformed into a solid wax through a process called hydrogenation. Soy wax is typically softer than paraffin wax, and its dense composition can result in worse scent performance. Therefore, soy wax candles may require longer curing times to achieve optimal fragrance release and intensity.
Environmental conditions, such as temperature and humidity, can also impact curing time. Warmer temperatures can accelerate curing, while high humidity may cause the wax to retain moisture and prolong the hardening process. Additionally, the type of fragrance oil used can influence curing time. Heavier and more complex fragrance oils may need more time to settle into the wax, while lighter and less delicate scents might cure faster.
The curing time for soy candles is essential to ensure the best fragrance performance. While it is possible to burn a soy candle after 24 hours of curing, it is recommended to wait for at least one to two weeks to allow the fragrance to reach its full potential. The longer curing time ensures that the fragrance oils have adequately bound with the wax, resulting in a more consistent and long-lasting scent release.

Curing with the lid off is recommended to allow excess moisture to evaporate
Curing soy candles is an important step in the candle-making process. It allows the fragrance oil and wax to bind together and ensures that the scent is adequately released when the candle is burned. While some candles can be burned after curing for only 24 hours, it is recommended that soy candles cure for at least one to two weeks. This allows the wax to harden and the fragrance to fully develop.
When curing soy candles, it is recommended to leave the lid off. This may seem counterintuitive, as leaving the candle uncovered may seem like it would cause the scent to dissipate. However, curing with the lid off allows for proper air circulation, which is crucial to the curing process. It helps the fragrance to develop fully and blend with the wax, resulting in a stronger scent when the candle is burned.
Additionally, curing with the lid off allows any excess moisture or volatile compounds to evaporate and escape from the candle. This is important because if these compounds remain in the candle, they can affect the candle's appearance and performance. For example, condensation may accumulate inside the container, which is not ideal. Therefore, by curing with the lid off, you are ensuring that your candle will not only smell better but also burn more effectively.
It is worth noting that some candle makers do choose to cure their soy candles with the lid on, especially if they are concerned about dust or other contaminants affecting the candle during the curing process. However, if you do cure with the lid on, it is important to ensure that the candle has completely cooled before covering it. Trapping heat inside the container can be a safety hazard. Ultimately, curing with the lid off is the best practice to ensure a high-quality candle with a strong and well-developed fragrance.
In conclusion, when curing soy candles, it is recommended to leave the lid off to allow for proper air circulation and the evaporation of excess moisture. This results in a candle with a stronger scent and better performance. While curing with the lid on may be tempting to protect the candle, it is not necessary and can even be detrimental to the curing process. By following the recommended curing process, you will end up with a higher-quality candle that burns effectively and fills your space with a delightful fragrance.

Curing time impacts the strength of the candle's scent
Curing time is essential in candle-making, as it allows the fragrance oil and wax to bind together and spread evenly before the wax sets. While it is possible to burn a candle after 24 hours of curing, this does not mean that the candle should not cure for longer. The longer curing time allows the candle to reach its maximum scent potential.
The ideal curing time for soy candles varies depending on the wax used and the desired scent throw. The general rule of thumb is to cure soy candles for 1-2 weeks, with some sources recommending up to 14 days for optimal scent throw. During the curing process, the wax cools and hardens, and the fragrance molecules are trapped within the crystal lattice, resulting in a stronger scent.
The curing time can also depend on the type of fragrance used. Heavier scents, such as bakery or gourmand fragrances, may be ready to burn more quickly, while lighter and more delicate scents may take longer to cure. Additionally, the size of the candle can play a role in scent throw, with smaller candles sometimes requiring shorter curing times.
While it is possible to burn a soy candle after a short curing time, it may not have a strong scent. The curing time allows the fragrance to bind with the wax and release a stronger aroma when burned. Therefore, it is recommended to cure soy candles for at least one week, and preferably for two weeks, to ensure the best scent throw.
The strength of a candle's scent is subjective, and it can be challenging to quantify. However, the curing time can impact the scent throw, which refers to the strength of the aroma when the candle is lit (hot throw) or unlit (cold throw). By allowing the candle to cure for longer, the fragrance has more time to bind with the wax, resulting in a stronger scent when the candle is burned.
