Soy candle making has become increasingly popular in recent years, primarily due to their eco-friendliness, longer burn time, and the absence of harmful substances that can be released during combustion. While the process may seem simple at first glance, there are many subtle mistakes that can lead to unsatisfactory results. Is your candle not burning evenly? It might be emitting smoke, not smelling as intense as you'd like, or not burning properly at all? If so, you may have made one of these common mistakes. In this article, we'll look at the most common mistakes beginner soy candle makers make and show you how to avoid them to ensure flawless results.
Too low or too high temperature for adding the oil
The temperature at which you add fragrance oil to soy wax plays a crucial role in the candle-making process. Getting this temperature incorrect can affect the candle's fragrance intensity and overall quality.
Adding fragrance oil at too low a temperature can cause the oil to not distribute evenly throughout the wax. This can result in uneven fragrance release during burning, leading to an inconsistent user experience.
Conversely, adding fragrance oil at too high a temperature can result in some of the oil evaporating before it is absorbed into the wax. This can result in a candle with a weaker scent than expected, which can be frustrating for those expecting a strong fragrance.
To avoid these errors, it's always a good idea to use a thermometer and carefully monitor the wax temperature before adding the oil. Most fragrance oil manufacturers provide recommendations for the ideal temperature for adding the oil to the wax, so it's worth following these recommendations and adjusting the process based on the ingredients you're using.
Incorrect candle priming rate
The rate at which you pour your candle is a key aspect of the candle-making process, which can have a decisive impact on its final quality. An incorrect pouring rate can lead to various aesthetic and functional issues.
Pouring too quickly: Pouring the wax too quickly can cause air bubbles to form inside the candle, which can cause it to burn unevenly.
Pouring too slowly: Pouring too slowly can cause the wax to harden prematurely at the edges of the candle-forming vessel, resulting in unevenness or "craters" on the candle's surface. This can also lead to uneven distribution of the fragrance oil in the wax if it was added before pouring.
For best results, it's best to pour the candle at an even, moderate rate, while ensuring the wax is at the recommended temperature. This will minimize the risk of these issues and ensure a high-quality product. Final results may also depend on the type of wax used, the type of fragrance oil, and the size and shape of the candle mold. Therefore, it's worth experimenting and adjusting the pouring rate to suit your specific working conditions.
Improper wick trimming
Trimming wicks is an important step in candlemaking, impacting both the aesthetics of the product and its functionality. While it may seem trivial, the correct wick length plays a crucial role in the quality of the candle's burn.
Trimming wicks too close to the candle can lead to several problems:
Weak flames: If the wick is trimmed too short, the candle flame may be small and not intense enough. This can affect the desired ambiance and the fragrance release of scented candles.
Uneven burning: A wick that is too short can cause the candle to burn unevenly, leading to "tunneling," a cavity in the center of the candle, instead of the wax burning evenly from the edges to the center.
Candle extinguishing: If the wick is trimmed too close to the candle's surface, there is a risk that the flame may self-extinguish as melted wax floods the wick.
To avoid these problems, it's recommended to trim the wick to the appropriate length, typically within 0.3 cm to 0.6 cm of the candle's surface. Of course, the exact optimal length may depend on the specific wick type and wax used in the candle. Therefore, it's always important to carefully read and follow the manufacturer's recommendations.
Adding fragrance oil to the drops
Adding fragrance oil "dropwise" allows for precise control of the fragrance amount in the candle, which is crucial for achieving the desired aromatic effect. However, such precision has its advantages and disadvantages.
Controlling the fragrance intensity: Adding fragrance oil dropwise allows for precise adjustment of the fragrance level. This allows for the creation of a candle with subtle fragrance notes or one with a stronger, more dominant aroma.
Economical use: Fragrance oils can often be quite expensive. Adding them dropwise allows for more economical use while minimizing the risk of overdoing it.
Risk of unevenness: However, if you're not careful, adding the oil dropwise can lead to uneven distribution of the fragrance in the wax. This is especially true if you add it directly to the finished wax and don't stir long enough.
Time-consuming: This method can be more time-consuming compared to measuring the oil using a measuring cup. When producing larger quantities of candles, this can be a challenge.
Converting to grams rather than drops: While adding oil drop by drop may seem like a simple and intuitive method of dosing, it's not the most precise method. In reality, different oils can have different densities, meaning that one drop of one oil doesn't necessarily equal one drop of another. Therefore, for accuracy and consistency, it's recommended to convert the fragrance oil to grams relative to the wax. This dosing method allows for accurate and repeatable proportions, which is crucial for achieving consistent quality and fragrance intensity from batch to batch. Using a kitchen scale to precisely measure the oil allows for better control and avoid potential errors that could impact the quality of the final product.
In summary, while adding fragrance oil drop by drop can provide a more personalized effect, it's important to do so carefully and consider all the factors that can influence the final result. If you're new to candle making, it's worth starting with smaller amounts, experimenting, and observing the results before moving on to larger production.
Ignoring wax melting and pouring temperature requirements
Temperature is one of the most important factors in the candle-making process. Ignoring the melting and pouring temperature requirements can lead to a number of problems that impact both the aesthetics and functionality of the finished product.
Uneven Cooling: An incorrect pouring temperature can lead to uneven cooling of the wax in the mold, which in turn can cause cracks, "craters," or other deformations on the candle's surface.
Fragrance Problems: If the wax is too hot when the fragrance oil is added, it can cause some of the fragrance components to evaporate, which in turn affects the final aroma of the candle. Conversely, a temperature that is too cold can result in uneven distribution of the fragrance throughout the candle.
Color Variation: An incorrect temperature can also affect the coloring of the wax if dyes are used in its production. An incorrect temperature can lead to uneven distribution of the dye, creating spots or streaks on the candle.
By adhering to recommended melting and pouring temperatures, as well as ensuring careful temperature monitoring throughout the process, you can avoid many of the above problems and ensure high-quality finished candles. Therefore, it's always important to follow the instructions of your raw material suppliers and regularly monitor working conditions.
Using the wrong wax for the type of mold
Choosing the right wax for a specific type of mold is crucial to successful candlemaking.
Hard wax for freestanding candles: Freestanding candles, such as columns or cones, require a harder wax to maintain their shape and prevent deformation during burning. Using softer wax in such molds can lead to the candle melting too quickly and making it difficult to remove the candle from the mold without damage.
Soft wax for poured candles: Poured candles, such as tealights or candles in glass containers, typically use softer wax. This allows the candle to burn more easily and evenly in a closed mold.
Aesthetic consequences: In addition to functional issues, the wrong wax choice can also affect the appearance of the final product. This can lead to uneven edges, air bubbles, or other undesirable effects.
Therefore, to achieve the best results, it is important to thoroughly understand the properties of different types of wax and select the right wax for the specific mold and candle's intended use. Experimenting and testing different combinations can also help you find the perfect solution for your specific candle concept.
In candle making, every detail matters.
