The length of time required to cure a candle depends on the type of wax used. While some candle makers use measurable criteria to determine whether a candle is ready, others rely on more subjective evaluations. Paraffin wax, for instance, reaches stability and is ready to burn as soon as it has cooled and hardened, usually within a day or two of pouring. In contrast, soy wax and other vegetable or natural wax blends require more curing time, with some candle makers recommending at least a week to achieve complete molecular stability. The curing time can also be influenced by the environment, with higher temperatures and humidity potentially requiring longer cure times.

What You'll Learn
The ideal cure time for parasoy candles is 5 days
While it is possible to achieve a strong hot throw on a candle that cures only 24 hours before burning, curing a candle for longer has benefits. Firstly, it can improve the safety of the candle. Harder candles may require larger wicks to generate enough heat to melt the wax. Burning a candle too soon after pouring may lead one to believe the wick is oversized if the wax melts too quickly. Waiting longer before burning would give different results. Secondly, longer cure times can improve the strength of the fragrance. One candle maker reported that a parasoy candle they had cured for several months emitted a very strong scent when burned.
The ideal cure time for a candle also depends on the type of wax used. Paraffin wax, for example, reaches stability as soon as it has cooled, so it does not need to cure for long. Soy wax, on the other hand, continues to harden over time, so it is recommended to cure soy candles for at least a few days, and preferably for 1-2 weeks. The environment in which the candle is curing can also affect cure times. In a humid environment, for example, it may take longer for candles to cure.
Ultimately, the ideal cure time for a parasoy candle is 5 days, but it is important to consider the type of wax used, the environment in which the candle is curing, and the desired strength of the fragrance when determining the ideal cure time for a particular candle.

Longer cure times can improve the strength of the scent
The length of time required to cure a parasoy candle is a topic of debate in the candle-making community. While some people believe that 24 hours is enough, others argue for longer cure times to improve the strength and quality of the scent.
The process of curing allows fragrance oil to "bind" to the wax. Longer cure times can enhance this process, resulting in a stronger and more durable scent. This is especially true for candles made with natural waxes, such as soy or parasoy, which continue to harden over time due to polymorphic crystallization.
The environment in which the candle is cured can also impact the curing process. Curing in a humid environment, for example, may require longer cure times as the goal of curing is to eliminate moisture. Similarly, the temperature of the room can affect cure times, with colder temperatures causing wax to cool and harden more quickly.
While the strength of a candle's scent is subjective and varies from person to person, longer cure times can improve the overall performance of the candle. This includes enhancing the hot throw, or the amount of fragrance released when the candle is burned. Longer cure times can also improve the burn performance of the candle, ensuring a more even and consistent melt.
Ultimately, the optimal cure time for a parasoy candle may vary depending on individual preferences and environmental factors. However, allowing for a longer cure time can improve the strength and durability of the scent, creating a more enjoyable and longer-lasting candle-burning experience.

The temperature and humidity of the environment can affect cure times
The temperature and humidity of the environment can significantly impact cure times for candles. Curing is the process of allowing a candle to rest after it has been poured and set, enabling the fragrance and colour to fully develop. This process can take anywhere from a few days to a few weeks, depending on the type of wax and fragrance used.
Temperature plays a crucial role in the curing process. Candles are typically cured in a cool, dry place, as higher temperatures can cause the wax to soften and burn faster, leading to uneven burning and dripping. This can ultimately shorten the candle's life. In contrast, lower temperatures can slow down the curing process, resulting in longer cure times.
Additionally, humidity levels can also affect cure times. The point of curing is to eliminate moisture, so humid environments may require longer cure times. High humidity can also warp the wax and degrade the fragrance oils, impacting the overall quality and performance of the candle. Therefore, it is recommended to store candles in a dry place away from direct sunlight and heat sources during the curing process.
The type of wax used in candle-making also interacts with the environment to determine cure times. For example, soy wax, a type of vegetable wax, continues to harden over its entire life due to its polymorphic nature. Crystals form in the wax in response to time and temperature, leading to a harder wax over time. On the other hand, waxes like paraffin reach almost full hardness within a day or two of pouring.
Overall, understanding the impact of temperature and humidity on cure times is essential for achieving optimal results in candle-making. By considering these environmental factors and making adjustments as needed, candle makers can enhance the performance and longevity of their candles.

The type of wax used determines the cure time
The type of wax used in a candle determines its cure time. Parasoy wax, for example, is a blend of soy and paraffin wax. Soy wax is a "vegetable wax" that continues to harden over its entire life due to its polymorphic nature. Crystals continue to form in the wax over time in response to temperature, resulting in harder wax. Therefore, candles made with soy wax will continue to harden over time, with the most significant hardening occurring within the first two weeks after pouring.
On the other hand, paraffin wax, which is another common component of parasoy wax, reaches almost full hardness within a day or two of pouring. Once cooled, paraffin wax candles are considered fully cured and ready to burn.
The blend of soy and paraffin wax in parasoy candles results in a cure time that is likely somewhere in between that of pure soy and pure paraffin wax candles. Candle makers using parasoy wax have reported cure times ranging from 5 days to 2 weeks, with longer cure times resulting in stronger scents.
In addition to the type of wax, other factors can also influence the cure time of a candle. For example, temperature and humidity can affect how long a candle takes to cure. In colder temperatures, candles may cool and harden almost instantly, potentially reducing the necessary cure time. However, in humid environments, longer cure times may be required to ensure that the candle is sufficiently dry.
Ultimately, the cure time for parasoy candles can vary depending on the specific blend of wax used, as well as environmental factors such as temperature and humidity. While some candle makers suggest a cure time of around 5 days, others recommend longer cure times of up to 2 weeks or more to achieve the best results in terms of scent and burn performance.

Burn testing is required to evaluate the performance of the candle
Burn testing is a crucial step in evaluating the performance and safety of a candle. It involves trialling the candle to observe how it burns and performs over multiple cycles. The process is not a quick one, and it can take a week or more to complete, depending on the testing framework. Each burn cycle will be different, and the candle should be burned in four-hour increments until it fails or the wax is completely burned. This extended testing period allows for an evaluation of the candle's performance throughout its entire life, not just during the initial burns.
There are several factors to consider when conducting a burn test. Firstly, the candle's components, such as the type of wax, fragrance oil, wick choice, and container shape, will influence its performance. Therefore, it is essential to test different wicks to determine which works best for your candle. Additionally, the melt pool, soot, and flame size should be observed holistically rather than individually. For example, a larger flame height may indicate that the candle is burning too hot, which could be a safety hazard.
Another important aspect of burn testing is evaluating the candle's fragrance, both when it is burning ("hot throw") and in its solid form ("cold throw"). The strength of the fragrance and how far away it can be smelled are crucial factors in determining the candle's performance. It is worth noting that scent is a subjective topic, and it can be challenging to measure accurately without specialised equipment.
Conducting burn tests is essential for ensuring the safety and performance of your candles, especially if you plan to sell them. These tests provide insight into how your candle performs as a whole, including the consistency of the wick, fragrance, and overall burning. By conducting thorough burn tests, you can optimise your candle's performance, make any necessary adjustments, and ensure it meets safety standards.
