Candles are a popular choice for creating a cosy atmosphere, but they can also be a safety hazard if not handled properly. The temperature of a candle varies depending on the part of the candle you're measuring. The hottest part is the flame, which can reach temperatures of up to 1,400 °F, while the molten wax can range from 120 °F to 400 °F. The type of wax, the size and material of the wick, and even the ambient air temperature can all influence how hot a candle flame gets. With such high temperatures, it's important to take precautions to avoid burns and other accidents.

The hottest part of a candle is the flame, reaching up to 1400 ºF
The hottest part of a candle is the flame, which can reach temperatures of up to 1,400 ºF. The temperature is hottest at the base of the flame, where the flame meets the candle wick, and decreases further away from the wick. The blue area at the base of the flame is the hottest part, reaching temperatures between 1400-1800°F. This is where the flame has the most oxygen, creating the ideal conditions for combustion.
The temperature of a candle flame can be estimated by its colour. The yellow part of the flame is cooler, at around 1200°F, while the outermost part, which is red to orange in colour, is the coolest area, with temperatures ranging from 800°F to 1000°F. The average candle flame generates between 80 to 100 watts of heat.
The temperature of a candle flame is influenced by several factors. The type of wax used affects the temperature, with different waxes burning at different temperatures. For example, paraffin wax has a melting point of around 99°F to 154°F, while beeswax has a higher melting point, typically between 144°F and 147°F. The purity of the wax also impacts the flame temperature, with impurities leading to a cooler burn.
The wick also plays a significant role in determining the temperature of a candle flame. The size, shape, and material composition of the wick can all influence the flame's temperature. Thicker wicks tend to produce larger and hotter flames, while thinner wicks generate smaller and cooler flames. Wooden wicks, for instance, tend to create slightly higher temperatures than cotton wicks due to their wider structure.
While the flame is the hottest part of a candle, the molten candle wax can also reach temperatures high enough to cause burns. The temperature of molten wax depends on the type of wax, its distance from the flame, and how long the candle has been burning. Molten wax can range from 120 ºF to over 400 ºF, and it is important to remember that it is not safe to touch.

The temperature of molten candle wax ranges from 120 ºF to 400 ºF
The temperature of molten candle wax varies, ranging from 120 ºF to 400 ºF. This temperature range is deceptive, as the wax is not as hot as the flame itself, which can reach temperatures of up to 1,400 ºF. The hottest part of the flame is the blue area at its base, where the flame has the most oxygen, and this is where combustion occurs. The yellow part of the flame is cooler, at around 1200 ºF, and the coolest part is the outermost red to orange area, at 800 ºF to 1000 ºF.
The temperature of the molten wax depends on the type of wax used. For example, paraffin wax, a common candle wax, melts at 99 ºF to 154 ºF, while beeswax, another popular choice, has a higher melting point of 144 ºF to 147 ºF. Soy wax has a melting point of around 130 ºF to 150 ºF. The melting point of the wax can give a conservative estimate of the temperature of the wax pool. For instance, a wax pool made of soy wax is at least 130 ºF, which is hot enough to cause second-degree burns.
The temperature of the molten wax is also influenced by how far it is from the flame and how long the candle has been burning. The container of the candle also heats up, with glass containers reaching temperatures of 100 ºF to 140 ºF, and metal containers reaching 125 ºF. These containers can get even hotter, with glass jars sometimes exceeding 180 ºF, which is a significant safety risk as it can cause the glass to crack or explode.
To avoid burns, it is important to never touch a burning candle or its molten wax. Always wait for the candle to cool down and the wax to solidify before handling it. To extinguish the candle, use a snuffler or wick dipper to avoid hot wax splattering.

Candle wax type influences the temperature of the flame
The temperature of a candle flame depends on several factors, including the type of wax, the size and material of the wick, and the surrounding environment (e.g. airflow and humidity). The flame's heat varies depending on which part of the flame is being measured.
The hottest part of a candle flame is typically the blue area near the base, where the flame has the most oxygen, making it the ideal place for combustion. This zone, known as Zone II, has temperatures reaching 1400°C (2552°F) or 1400-1800°F. The blue colour is caused by chemiluminescence.
The yellow part of the flame, or Zone IV, is cooler, with temperatures of approximately 1200°F or 800°C to 1000°C (1830°F). The outermost part of the flame, which is red to orange in colour, is the coolest, with temperatures ranging from 800°F to 1000°F.
The type of wax used in a candle can impact the temperature of the flame. Different waxes have different melting points, which can give an indication of the temperature of the wax pool. For example, paraffin wax, a common candle wax, melts at around 99°F to 154°F, while beeswax, another popular option, has a higher melting point, typically between 144°F and 147°F. Soy wax, meanwhile, has a melting point of approximately 130-150°F. The purity of the wax can also influence the flame's temperature, with impurities often resulting in a cooler burn.
The wick's size, shape, and material composition can also affect the temperature of the flame. A thicker wick generally produces a larger and hotter flame, whereas a thinner wick tends to generate a smaller and cooler flame. Cotton wicks are the most common type and provide a stable burn, whereas wooden wicks can create a slightly higher temperature due to their broader structure.
