Curing time: 24-48 hours for paraffin candles, 1-2 weeks for soy candles
Curing a candle is the process of allowing it to rest so that its scent and wax can bind and incorporate with each other. This process is essential to ensure that your candle burns and smells its best. The curing time varies depending on the type of wax used, with paraffin candles requiring 24-48 hours and soy candles needing 1-2 weeks.
Paraffin wax is more stable and does not change much within 24-48 hours after pouring. Candle makers can test the scent throw by lighting the candle during this curing time, as the wax is still soft and will create a wider and deeper melt pool. However, burning too early can affect the true results, as the wax continues to harden and the melt pool may develop more slowly after another week.
Soy wax, on the other hand, takes longer to cure due to its natural tendency to encapsulate fragrance oil molecules. It is recommended to let soy candles cure for a minimum of 3-4 days and up to 2 weeks. During this time, the wax gradually hardens, and burning a soy candle too early may require a larger wick to generate enough heat to melt the wax.
The curing process can be done with or without lids on the candles. Curing with lids helps maintain scent integrity by minimising exposure to environmental factors like light and air, which can degrade fragrance oils over time. It also protects the candles from dust and debris. However, curing without lids allows for better air circulation, which can be beneficial in controlled environments, as it allows volatile organic compounds (VOCs) to dissipate quickly, potentially leading to faster curing and a stronger fragrance.
The optimal curing time and conditions depend on various factors, including the type of wax, fragrance load, and colourant used. Environmental factors such as temperature and humidity also play a significant role in the curing process. It is recommended to cure candles in a cool, dark place, maintaining a consistent warm temperature to prevent the wax from cooling too quickly. Additionally, preheating the containers with a heat gun or in a low oven can help slow down the setting process.

The role of lids: lids on for consistent scent, lids off for quicker curing
The role of lids during the candle-curing process is a nuanced topic, and the optimal approach depends on various factors. Keeping the lids on offers several advantages. Firstly, it helps maintain a consistent scent profile by minimising exposure to environmental factors such as light and air, which can degrade the integrity of fragrance oils over time. This ensures that the scent your customers experience aligns closely with the pre-cure fragrance. Lids also protect the candles from dust and debris, contributing to a more uniform curing process.
On the other hand, curing candles with the lids off has its own benefits. Removing the lids allows for better air circulation, which can be advantageous in controlled environments with managed humidity and temperature. This increased airflow facilitates the quicker dissipation of volatile organic compounds (VOCs), resulting in a reduced initial harshness in the scent and potentially accelerating the curing process.
The decision to cure with lids on or off ultimately depends on the specific circumstances and goals. For instance, if maintaining a consistent fragrance profile is a priority, using lids during curing may be preferable. However, if the objective is to expedite the curing process and mitigate any harshness in the scent, opting for lidless curing could be more advantageous.
It is worth noting that the curing process itself is a complex and subjective matter. The optimal curing time can vary based on factors such as the type of wax, fragrance load, and even the presence of colourants. While some candles may only require 24 to 48 hours of curing, others might need up to two weeks or more to fully develop their fragrance and performance characteristics.
Ultimately, the curing process is a critical aspect of candle-making, allowing the scent and wax to bind together harmoniously. The role of lids during this process is just one of the many considerations that candle makers must navigate to create the perfect product.

Burn testing: test for at least a week to ensure consistent results
Burn testing is a critical step in candle-making to ensure safety and optimal performance. It involves evaluating a candle's performance from the first to the last burn. The goal is to ensure a normal burn rate, minimal soot production, and overall safety for the user. To conduct a basic burn test, follow these steps:
- Prepare a comfortable and safe testing area: Clear your schedule and find a suitable space. Ensure the area is free of drafts, and place the candle on a clean, flat, heat-resistant surface. Use a tray to catch any melted wax in case of spills.
- Label and prepare the candle: Clearly label the candle with its ingredients and components, including the type of wax, fragrance oil, fragrance load, dyes used, wick choice, and container details. Trim the wick to 1/4 inch (6 mm) before lighting.
- Conduct the burn test: Allow the candle to burn for a maximum of 4 hours at a time. Supervise the candle at all times during the burn test and ensure it is not left unattended. After each interval, provide adequate time for the melt pool to re-harden (approximately 5-6 hours) before starting the next burn. Continue this process until the candle either fails or runs out of wax.
- Evaluate the results: Pay attention to the candle's performance during and after each burn. Note any abnormalities or concerns. The burn test will help you determine if adjustments are needed, such as changing the wick size or adjusting the fragrance load.
When burn testing, it is essential to test for at least a week to ensure consistent and accurate results. This extended testing period is particularly crucial for natural waxes like soy, which continue to harden and change over time. The first two weeks are critical for the performance and stability of natural waxes, and testing during this period will provide more reliable data.
Additionally, consider the frequency of burn testing. It is recommended to periodically test your candles, especially those made with soy and natural waxes due to their natural variance. Checking your candle line at the start of each season or bi-annually can help ensure consistent quality.

Environmental factors: temperature, humidity, and composition of the candle affect curing
Environmental factors such as temperature, humidity, and the composition of the candle all influence the curing process. Maintaining a consistent room temperature of around 70°F (21°C) is recommended for optimal candle performance. Higher temperatures can cause scented candles to soften, leading to faster and uneven burning, and potentially a shorter candle life. However, a higher temperature can also enhance the fragrance release, making the scent more prominent.
Humidity levels should be kept between 40% and 60% to ensure the candle burns cleanly and evenly, maximising both scent throw and burn time. Extreme temperatures and high humidity can warp the wax and degrade the fragrance oils, affecting the overall quality and performance of the candle when lit. Therefore, candles should be stored in a cool, dry place away from direct sunlight and heat sources.
The composition of the candle, specifically the type of wax and fragrance oil used, also plays a crucial role in the curing process. Different waxes have different curing times; for example, vegetable waxes like soy continuously harden over their life, whereas more stable waxes like paraffin don't change much after 24-48 hours. The fragrance oil used can also affect curing, as excess oil can pool in the candle if there is too much or if it is poorly mixed.
The time and temperature during curing lead to the formation of crystals in the wax, resulting in a harder wax over time. This harder wax requires more heat energy to melt, which can impact the performance of the candle over time. Therefore, it is important to consider the environmental factors during the curing process to ensure the candle cures evenly and effectively.
Additionally, the environment in which the candle is burned can also affect its performance. Placing a candle in an area with drafts, heat sources, or direct airflow from air conditioners or humidifiers can alter flame behaviour and affect how the candle burns. Being mindful of these environmental factors can help enhance the candle's performance and prolong its life.

Stirring is an important step in the candle-making process. It ensures that the fragrance oil is evenly distributed throughout the wax, resulting in a consistent scent when the candle is burned. Here are some detailed instructions and tips for stirring fragrance oil into wax:
Firstly, it is crucial to add the fragrance oil at the appropriate temperature. Following the wax manufacturer's instructions is essential. A good starting point is typically around 180 degrees Fahrenheit. This higher temperature helps to ensure that the fragrance oil binds effectively with the wax.
Next, the stirring process itself is straightforward but requires patience and attention to detail. Use a gentle stirring motion and continue stirring for at least one full minute. For best results, aim for two minutes to ensure thorough mixing. This process helps to prevent issues such as wet spots and uneven fragrance distribution.
While stirring, be mindful not to over-stir, as this can introduce too much air into the mixture, causing air bubbles that affect the candle's appearance and performance. Stirring gently but continuously for the recommended time will help ensure a smooth and even blend.
The stirring step is particularly crucial when working with soy wax or other vegetable waxes. These waxes are known for their ability to encapsulate fragrance oil molecules, resulting in a stronger and more consistent scent throw. However, soy wax takes longer to bind with the fragrance oil, so adequate stirring is essential to achieving optimal results.
Additionally, consider curing your candles with lids on to protect them from dust and debris. This method also helps maintain a consistent fragrance profile by minimising fragrance dissipation. However, curing with lids off promotes better air circulation, which can be advantageous in controlled environments and may lead to faster curing times.
In conclusion, stirring fragrance oil into wax for at least one minute is a vital step in candle-making. It ensures that the fragrance is evenly distributed, enhancing the candle's scent and performance. By following the recommended stirring techniques and considering the curing process, you can create candles with a consistent and pleasing fragrance.
