The temperature at which candles melt depends on the type of wax used to make the candle. For example, soy wax has a relatively low melting point of 49-82°C, while paraffin wax has a slightly lower melting point of 46-68°C. Beeswax, which is a natural wax produced by honeybees, has a higher melting point of 62-65°C. Waxes with higher melting points tend to burn more slowly and evenly, while those with lower melting points may melt too quickly, resulting in shorter burn times. Candle makers need to know the melting point of the wax they are using to ensure optimal results, such as a smooth pour, improved fragrance throw, and enhanced candle durability.

Melting points vary depending on wax type
Melting points vary depending on the type of wax used in a candle. The melting point of a candle is critical, as it determines how well a candle burns, how long it lasts, and how effectively it releases its fragrance.
Paraffin wax, for example, has a melting point that typically falls between 46°C and 68°C (115°F and 155°F). However, some sources state that it can be as low as 46°C-61°C (115°F-142°F) or 120°F-160°F. The variation in melting points may be due to different formulations and intended uses, as well as the presence of additives or impurities. Paraffin wax is known for its relatively low melting point, making it versatile and easy to work with.
Soy wax, on the other hand, has a lower melting point than paraffin wax. Low-melt soy wax melts at around 130°F (52°C-54°C), while high-melt soy wax melts at approximately 150°F (65°C-66°C). This lower melting point means that soy wax candles will begin to melt and release their fragrance at a lower temperature than paraffin wax candles.
Beeswax has a higher melting point than both paraffin and soy wax, typically ranging from 62°C to 65°C (143°F to 149°F), or 145°F according to another source. This higher melting point allows beeswax candles to burn at higher temperatures for longer periods, making them ideal for extended use.
Another type of wax with a high melting point is microcrystalline wax, which ranges from 145°F to 195°F, depending on the grade. Waxes with higher melting points, like microcrystalline wax, tend to burn more slowly and evenly, resulting in longer-lasting candles.
Gel wax also has a high melting point of around 82°C (180°F). This type of wax offers a long burn time and can outlast traditional wax candles.
The melting point of a candle is not just dependent on the type of wax but also on the additives, impurities, and specific formulations used. Therefore, it is essential to refer to the manufacturer's guidelines for precise melting point information. Additionally, the pouring temperature of wax can vary based on factors such as the size and type of mould or container being used.

Melting temperature affects candle performance
The melting temperature of a candle is a critical factor in determining its performance and quality. Different types of wax have different melting points, and this variation influences the candle's burn time, durability, and fragrance release.
Waxes with higher melting points, such as beeswax, tend to burn more slowly and evenly, resulting in longer-lasting candles. Beeswax, with a melting point of 62-65°C (144-149°F), is considered a hard wax and is known for its natural, subtle scent and honey-like colour. Its high melting point makes it ideal for candles as it can burn at a higher temperature for an extended period. Additionally, beeswax is biodegradable, eco-friendly, and produces less smoke when burnt.
On the other hand, waxes with lower melting points, such as soy wax, may melt too quickly, resulting in shorter burn times. Soy wax has a relatively low melting point, typically ranging from 49-82°C (120-180°F). This low melting point allows soy wax candles to release their fragrance at a lower temperature compared to candles made from wax with higher melting points, such as paraffin wax. However, it is important to note that soy wax has a longer burn time than many other types of wax, making it a cost-effective and sustainable option.
The melting temperature also affects the fragrance performance of candles. Adding fragrance oil at the appropriate temperature, typically around 79-85°C (175-185°F), ensures that it binds properly with the wax, preventing premature evaporation or burning off. This temperature range optimises scent throw and enhances the overall fragrance experience.
Furthermore, melting temperature plays a crucial role in achieving smooth pouring and reducing imperfections. When wax is melted at the correct temperature, it pours more smoothly into containers or moulds, minimising issues like air bubbles, frosting, and surface cracking. This results in candles with improved durability and burning efficiency.
In summary, the melting temperature of a candle directly influences its performance. It determines the burn time, fragrance release, durability, and overall quality of the candle. By selecting the appropriate wax type and carefully controlling the melting temperature during production, candle makers can create candles that perform optimally and provide a pleasant experience for consumers.

Heating wax above 250°F is a fire hazard
The ideal temperature for melting candle wax depends on the type of wax being used. For example, soy wax melts at temperatures ranging from 49°C to 82°C, while paraffin wax has a slightly lower melting point range of 46°C to 68°C. Beeswax, which is another popular option for candle-making, has a melting point range of 62°C to 65°C.
Regardless of the type of wax, it is important to note that overheating wax can degrade its quality, leading to discoloration and a poor texture. This is why it is crucial to follow specific temperature guidelines for each type of wax. For example, gel wax, which has a high melting point of around 82°C, offers a longer burn time and can outlast traditional wax candles.
When melting wax, it is essential to use the appropriate equipment to ensure safety. While some people opt for the faster microwave method, the most popular way to melt wax at home is by using a double boiler. This method involves using steam as a heat source to melt the wax, and it is important to not let the wax exceed 80°C when using this technique.
Heating wax above 250°F (121°C) can pose a fire hazard. To avoid this, always follow safety precautions such as using a double boiler or a wax melting pot. Additionally, avoid heating wax directly on a stove, as it can burn easily and become a fire hazard if it exceeds 250°F.
