Frosting on candles refers to the buildup of a white crystalline layer on the surface of natural waxes, especially soy. It is caused by tiny crystal growth that forms on the top and sides of the wax. Frosting occurs due to temperature fluctuations as the wax cools and hardens, and it can also be influenced by factors such as fragrance oil, dye, and the environment. While frosting may affect the candle's appearance, it does not impact its performance or fragrance. Candle makers can minimise frosting by controlling temperature conditions during production and storage, using additives, and being mindful of the amount of colour and fragrance used.

What You'll Learn
Frosting is a natural effect of soy candles
Frosting is a common issue with soy candles, and it occurs when the wax on the outside of the candle cools down too much. This results in an unattractive layer of frost on the exterior of the candle, which can prevent light from escaping. Frosting is caused by the presence of crystals on the wax, which can be influenced by temperature changes, the choice of fragrance, dye, containers, and the environment. It is a natural effect of soy candles as the wax tries to return to its natural form.
The appearance of frosting on a candle is similar to that of frost on a chilly windowpane. It resembles a white, crystalline layer on the surface of the wax, giving it a grainy or shiny look. This phenomenon is a result of polymorphism, where crystals inconsistently form in a substance. While it may seem like a problem, frosting is purely cosmetic and does not impact the performance or fragrance of the candle.
To minimise the formation of frosting, candles should be stored in a cool, dry place, away from direct sunlight. This helps prevent the wax from melting and re-solidifying, which can lead to frosting. Additionally, burning candles regularly is important because if they are left unused for too long, the wax can start to crystallise.
While complete prevention of frosting is challenging, some practical solutions can help minimise its occurrence. Maintaining a consistent temperature during the cooling and curing process is crucial. Adjusting the pouring temperature of soy wax to no more than 185 degrees Fahrenheit can also help. Experimenting with additives such as stearic acid may improve the appearance of frosting in soy wax.
Although frosting may not be aesthetically pleasing, it is a natural and expected side effect of soy wax candles. It is a testament to the natural composition of the candle, and with some care and attention to storage and temperature conditions, its formation can be minimised.

Frosting is caused by tiny crystal growth
Frosting is a common issue with candles, especially soy candles, and is caused by tiny crystal growth. This phenomenon occurs when the wax on the outside of the candle cools too much, leading to an unattractive layer of frost on the exterior. While frosting may not be aesthetically pleasing, it does not impact the performance of the candle. The crystals form due to polymorphism, a condition where crystals inconsistently form in a substance.
The appearance of frosting can be influenced by various factors, including temperature changes, time, fragrance oil, dye, and the environment. Temperature plays a critical role, especially during the initial stage of a candle's life. Preventing rapid temperature changes and maintaining a consistent temperature during the cooling and curing process can help minimise frosting. Additionally, the use of certain additives, such as stearic acid, can also impact the formation of frosting.
To prevent frosting, it is recommended to store candles in a cool, dry place, away from direct sunlight and draughts. Burning candles regularly and avoiding long periods of inactivity can also help, as allowing candles to sit for too long can lead to wax crystallisation. Proper storage and usage can help maintain the appearance of candles and prevent the formation of frosting.
While complete prevention of frosting may be challenging, there are practical solutions to minimise its formation. These include strategic placement of labels to hide problem areas and the use of proprietary wax blends by luxury candle makers to achieve a desired appearance. By understanding the factors that contribute to frosting and implementing preventive measures, chandlers can create candles that not only perform well but also maintain their aesthetic appeal.

Frosting can be prevented by storing candles properly
Frosting, or blooming, is a natural effect of using vegetable waxes, especially soy wax. It is caused by tiny crystal growth that forms on the top and sides of the wax, resulting in a frosty appearance. While frosting does not impact the performance of the candle, it is often considered unpleasant and a sign of poor-quality candles.
To prevent frosting, it is important to understand the factors that contribute to its formation. Temperature fluctuations are a critical factor in the formation of frosting. Allowing newly-poured candles to cure for two weeks in an area with stable temperature and humidity can help reduce the likelihood of frosting.
The choice of fragrance, dye, containers, and environment also play a role in preventing frosting. Fragrance oils and dyes can upset the unstable structure of soy wax, increasing the likelihood of frosting. Using opaque or textured containers can help hide the appearance of frosting, as the crystals will be less noticeable.
Additionally, it is important to recognize that once the candle leaves the workshop, factors such as shipping, wholesale storage, and customer care can also impact the formation of frosting. While it is challenging to completely prevent frosting, understanding these factors and implementing strategic measures can help minimize its occurrence.
Overall, preventing frosting involves considering various aspects of candle-making, from the choice of materials to the storage and transportation of the final product. By taking these factors into account, candle makers can reduce the likelihood of frosting and improve the appearance and customer perception of their candles.

Frosting may be minimised by avoiding temperature fluctuations
Frosting, a natural byproduct of natural wax, is characterised by a whitish coating on candles. It is caused by tiny crystal growths that form on the top and sides of the wax. While frosting does not affect the burnability or fragrance of a candle, it is considered undesirable by some.
Frosting is almost inevitable with soy candles due to the polymorphic nature of soy wax, which causes crystals to form inconsistently. Temperature fluctuations during the cooling and curing process can exacerbate this, as crystals may form in different places and be more noticeable. Therefore, maintaining a consistent temperature during these stages is crucial for minimising frosting.
To avoid temperature fluctuations, it is recommended to cure candles for 1-2 weeks in an area with stable temperature and humidity levels. Additionally, the pouring temperature of soy wax should not exceed 185 degrees Fahrenheit. By controlling these factors, you can reduce the likelihood of frosting caused by temperature variations.
While it is challenging to completely prevent frosting, blending soy wax with paraffin or additives can help resist crystallisation. Some soy wax manufacturers offer blends with additives to stabilise crystal structures and improve performance. Alternatively, you can mask the appearance of frosting by using lighter wax colours or opaque containers, as frosting is less visible in these conditions.
In summary, while frosting may be undesirable aesthetically, it is a natural occurrence in soy candles due to the polymorphic nature of soy wax. By controlling temperature fluctuations during the curing and cooling stages, you can minimise the formation of noticeable crystals and improve the appearance of your candles.

Frosting is purely cosmetic and does not impact candle performance
Frosting, which appears as a white, crystalline layer on the surface of natural wax candles, is a purely cosmetic issue. It is caused by the presence of crystals on the wax and can occur for a variety of reasons. One of the main causes is temperature change, especially during the early stages of a candle's life. When the wax cools too much, crystals may form on the top and sides of the wax, resulting in a frost-like appearance. While this may be undesirable aesthetically, frosting does not impact the performance of the candle. It does not affect the burn ability or fragrance of the candle and many people believe that frosted candles burn more evenly and slowly than non-frosted candles.
Another factor that contributes to frosting is the presence of additives such as fragrance oils and dyes. These additives can upset the already unstable structure of soy wax, making it more prone to crystal formation. Additionally, the choice of fragrance, dye, containers, and environment can also play a role in the likelihood of frosting formation.
While there is no silver bullet to preventing frosting entirely, there are some strategies to minimise its occurrence. One method is to store candles in a cool, dry place, away from direct sunlight. This helps prevent the wax from melting and re-solidifying, which can lead to frosting. Burning candles regularly is also recommended, as allowing candles to sit for too long can result in wax crystallisation.
For candle makers, experimenting with different pouring temperatures and additives like stearic acid can help minimise the appearance of frosting. Additionally, using clear wax instead of coloured wax can reduce the likelihood of frosting. While frosting may be undesirable from an aesthetic standpoint, it is important to emphasise that it does not impact the functionality of the candle.
In summary, frosting on candles is a natural occurrence that is purely cosmetic and does not affect the performance or quality of the candle. It is caused by crystal formation due to factors such as temperature changes and additives. While it may be undesirable visually, it does not impact the burn ability or fragrance of the candle and is a common issue that many candle makers and enthusiasts encounter.
