Soy wax candles
When making soy wax candles, it is important to consider the hardening and curing times. The hardening process refers to the time it takes for the wax to become solid and handleable, while curing refers to the continuous hardening of the wax that ensures optimal burn quality and even distribution of fragrance and colour.
Soy wax generally takes about 3-4 hours to harden to the point where it can be handled safely. However, for complete curing, it is recommended to wait for at least 24-48 hours. The curing process ensures that the candle performs optimally when burned, with a strong hot throw and even fragrance distribution.
Several factors can influence the hardening and curing times of soy wax candles. These include room temperature, additives, and container size. For example, cooler environments can accelerate the hardening process, while warmer temperatures may slow it down. Additionally, larger containers retain heat longer, causing the wax to take more time to cool and set. Additives such as stearic acid can help the wax harden faster, while beeswax may slow down the hardening process but improve the overall burn quality.
To achieve the best results, it is recommended to pour and cool soy wax candles in a room with a stable, moderate temperature. Allowing the candles to cure for at least a few days, and up to two weeks, will ensure the optimal performance of the candle in terms of burn quality, scent throw, and even distribution of fragrance and colour.

Paraffin wax candles
The curing process in candle-making is when the wax and fragrance oils bind together, allowing the scent and colour to fully develop. This process takes anywhere from a few days to a few weeks, depending on the type of wax and fragrance used. Paraffin wax candles usually have a curing time of 1-2 days, although some fragrances may require longer.
The candle-making community believes that the most hardening occurs within the first 14 days after pouring, but changes can continue for weeks to months. More stable waxes like paraffin don't change much 24-48 hours after pouring.
The curing time for candles can be influenced by the type of wax, fragrance oil, size and shape of the candle, and environmental conditions. Larger candles may need more time to cure than smaller ones, and irregular shapes may require extra time for the scent and colour to develop fully. It's important to cure candles in a cool, dry place to ensure the best results and prevent melting or sweating.
During the curing process, fragrance oils are distributed evenly throughout the wax, creating a stronger and more vibrant candle. Curing is essential to providing customers with an epic experience, as it ensures that the first burn is pleasant and effective.
To achieve the best results, it's advisable to pour and cool candles in a room with a stable, moderate temperature. Additives such as stearic acid or beeswax can alter the hardening time, with stearic acid speeding up hardening and beeswax potentially improving burn quality. The size of the candle container also matters, as larger containers retain heat longer, causing the wax to take more time to cool and set.

Beeswax candles
To make beeswax candles, you will need beeswax, coconut oil, candle wicks, wick stickers, glass or ceramic jars, a bamboo skewer or wooden stick, and a pot. You will also need a heat source, such as an electric hot plate or a stove, and a melting pot or a large glass jar that can withstand heat.
The first step is to prepare your workspace by covering the table with wax paper, newspaper, or a large poster board. This will help with the cleanup process. If you are using a double boiler, fill the bottom pot halfway with water and place it on the heat source. Turn the heat to medium and bring the water to a hot simmer. Do not let the water boil, as this can burn the wax or splash into the pot.
Next, you will need to melt the beeswax. Place your beeswax into the melting pot or glass jar and heat it until the wax reaches a temperature of 150-160°F. If using a double boiler, you can place the beeswax directly into the top pot. If using a glass jar, fill the pot with water and place the jar with beeswax inside, ensuring that the water level covers the height of the beeswax. Heat the water until it reaches a gentle boil. Stir the wax occasionally with a wooden skewer or stick to prevent it from burning.
Once the wax is melted, turn off the heat and add in the coconut oil, stirring to combine. Adding coconut oil helps the candle burn more consistently and prevents tunnelling. While the wax is melting, prepare your candle jars by placing a wick sticker at the bottom of each wick and centring it in the middle of the jar. You can also use a wood wick for a more natural look. Secure the wick in place by wrapping it around a skewer and laying it across the top of the jar.
Now you are ready to pour the wax into the jars. Pour slowly and consistently until the wax slightly overflows the top of the jar. If you notice craters forming, continue topping off the candle with more hot wax until it cools. It is important to let the candle fully cool before removing it from the mold, which can take 1-1.5 hours in a 60-70°F indoor space.
Finally, trim the wicks to 1/2" and your beeswax candle is ready to use! However, it is recommended to let the candle cure for 1-2 weeks before burning to allow the fragrance and colour to fully develop. Curing is the process of continuous hardening of the wax and dispersal of fragrance oils, resulting in a stronger, more vibrant candle. During this time, store the candles in a cool, dry place away from direct sunlight and heat sources to prevent melting or sweating.

The impact of temperature
Temperature plays a significant role in the curing process of candles. The ideal temperature for a candle to cure is room temperature, in a well-ventilated area. Colder temperatures can accelerate the curing process, while warmer temperatures slow it down. This is why it is recommended to cure candles in a room-temperature environment.
The size of the candle container also affects the curing time. Larger containers retain heat for longer, causing the wax to take more time to cool and set. On the other hand, smaller containers will cool and harden more quickly. Therefore, the size of the container can determine the curing time, with larger candles requiring more time to cure than smaller ones.
The type of wax also impacts the curing time. For example, soy wax takes longer to cure than paraffin wax. Soy wax typically requires 48 to 72 hours to cure, while paraffin wax usually needs 24 to 48 hours. Beeswax candles generally require the least amount of curing time, with 12 to 24 hours often being sufficient.
The ambient temperature during the curing process is crucial, as it can affect the final product. If the room temperature is too high, the candles may remain soft or mushy, indicating that they have not cured properly. This can also happen if the wax was overheated during the melting process. Therefore, it is important to maintain a stable room temperature and avoid overheating the wax to ensure a successful cure.
Overall, temperature plays a critical role in the curing process of candles. By controlling the ambient temperature, the size of the container, and the type of wax, one can ensure that candles cure properly and achieve optimal burn performance.

The importance of curing
Candle curing is a critical component of candle-making. It is the process of allowing the candle wax to harden and fully set, which ensures optimal burn performance. The curing time can vary depending on several factors, including the type of wax, the size of the candle, and the ambient temperature.
For soy wax candles, the curing process generally takes longer compared to other types of wax, such as paraffin wax. Soy wax typically requires 24 to 48 hours of curing time, with some sources recommending up to 72 hours for optimal results. This extended curing period allows the soy wax to fully harden and ensures that the fragrance and colour are well distributed throughout the candle.
The size of the candle container also affects the hardening time. Larger containers retain heat longer, causing the wax to take more time to cool and set. On the other hand, smaller containers will cool and harden more quickly. Additionally, colder temperatures can accelerate the hardening process, while warmer temperatures might slow it down.
The curing process is important because it allows the wax and fragrance oils to incorporate and bind together evenly. This results in a stronger and more consistent scent throw when the candle is burned. A properly cured candle will provide a better experience for the user, as it will burn more efficiently and release the desired fragrance effectively.
While it is possible to burn a candle that has cured for a shorter period, it is not recommended. Insufficient curing time can lead to issues such as uneven burning, tunnelling, and a weaker scent throw. Therefore, it is worth the wait to allow your candles to cure for the recommended amount of time, or even longer if you have the patience. This will ensure that your candles perform at their best and provide an enjoyable experience for yourself or your customers.
