Candles are a popular way to add ambiance and fragrance to any room. They are used in a variety of settings, including homes, restaurants, and spas.
However, many people are curious about how candles behave under different conditions, including exposure to sunlight. One question that frequently arises is: Do candles melt in the sun?
In this article, we will explore this topic in detail and try to analyze the important factors involved to this question.
Many candle enthusiasts may wonder if it is safe to leave candles in direct sunlight or if the heat from the sun will cause the candles to melt. This is a valid concern as candles can be a fire hazard if not used properly. In this article, we will explore whether candles can melt in the sun and what factors can impact their melting point.
What Are Candles Made Of?
Candles are typically made of wax, which can be derived from a variety of sources including beeswax, paraffin, soy, or palm oil. The type of wax used can affect the candle’s appearance, burn time, and scent throw.
In addition to wax, candles also contain a wick, which is usually made of cotton or another type of fiber and may be treated with chemicals to improve its burn properties. Candles may also contain dyes, fragrances, or other additives to enhance their aesthetic or olfactory appeal.

How Can These Materials Affect a Candle’s Melting Point?
The materials used in making candles can affect their melting point. Different types of wax, such as paraffin wax, soy wax, and beeswax, have different melting points.
For example, paraffin wax has a melting point of approximately 130-135 degrees Fahrenheit, while soy wax has a lower melting point of around 120-125 degrees Fahrenheit.
The type of wick used can also affect the melting point, as a thicker wick will generate more heat and cause the candle to melt faster.
Additionally, the type of fragrance oil or dye used can affect the melting point, as some additives can lower the melting point of the wax.
Ultimately, the materials used in making candles can impact the candle’s ability to withstand high temperatures, including exposure to the sun.
Factors that Affect a Candle’s Melting Point
Temperature and sunlight exposure, particularly prolonged exposure to direct sunlight or high temperatures, can cause candles to melt or warp.
Wax Type and Density
Wax type and density can also affect a candle’s melting point. Some waxes, such as paraffin wax, have a lower melting point and may melt more easily in the sun compared to other waxes like beeswax or soy wax. The density of the wax can also play a role; denser waxes may have a higher melting point and be more resistant to melting.
Wick Size and Material
Wick size and material can also impact the melting point of a candle. A wick that is too small for the candle can cause the wax to pool around it and potentially melt faster. The type of material used for the wick can also affect the melting point; for example, a cotton wick may have a lower melting point compared to a braided or twisted wick.
Fragrance and Color Additives
fragrance and color additives can impact the melting point of a candle as well. These additives can affect the chemical composition of the wax, which can impact the melting point and overall stability of the candle.
How Sunlight Exposure Can Cause a Candle To Melt?
Sunlight exposure can cause a candle to melt due to the heat generated by the sun’s rays. When a candle is exposed to direct sunlight or high temperatures, the wax can soften and eventually melt, causing the candle to lose its shape and structure. This is because the melting point of the wax is exceeded by the external heat, causing it to become unstable and change its physical state.
Sunlight exposure can also cause discoloration and fading of the candle’s color and fragrance due to the breakdown of the additives used in the wax. It is important to store candles in a cool, dry place away from direct sunlight to prevent them from melting or losing their integrity.
Major Necessary Conditions
Sunlight exposure can cause a candle to melt when the candle is exposed to high temperatures for an extended period of time. This is because the heat from the sun causes the wax in the candle to soften and eventually melt.
Additionally, if the candle is left in direct sunlight, the heat can cause the wax to expand and potentially crack the container or the wax surface. This is more likely to occur with candles that have a lower melting point or are made with a softer wax.
Overall, the conditions necessary for sunlight to cause a candle to melt include high temperatures, prolonged exposure, and the type of wax used in the candle.
How to Protect Candles From Melting In the Sun?
To protect candles from melting in the sun, there are several precautions that can be taken:
1. Store Candles in the Shade
This is the easiest and most effective way to protect candles from melting. Keeping them in a cool, dark place like a cupboard or drawer will prevent them from being exposed to sunlight and high temperatures.
2. Avoid Placing Candles in Direct Sunlight
When using candles, make sure to place them in a shaded area away from direct sunlight. This will reduce their exposure to heat and help prevent melting.
3. Use Candle Holders
Candle holders can help protect candles from direct sunlight and high temperatures by providing a barrier between the candle and the surrounding environment.
4. Opt for Heat-resistant Candles
Certain types of candles, such as beeswax and soy wax candles, are more heat-resistant than others. Choosing these types of candles can help reduce the risk of melting in the sun.
5. Trim the Wick
A long wick can cause a candle to burn hotter, increasing the risk of melting. Trimming the wick to ΒΌ inch can help reduce the temperature of the flame and prevent melting.
Tips for storing and using candles in hot temperatures
Here are some tips for storing and using candles in hot temperatures:
1. Store Candles in a Cool, Dark Place
Keeping candles in a cool, dark place, away from direct sunlight, can help prevent them from melting or warping.
2. Avoid Using Candles in Hot Temperatures
If the temperature outside is hot, it’s best to avoid using candles altogether. Instead, opt for battery-operated candles or diffusers to add fragrance to your home.
3. Use Candle Holders
Placing candles in holders can help protect them from direct sunlight and prevent them from melting or warping.
4. Trim the Wick
A longer wick can cause a candle to burn hotter, which can increase the risk of melting. Be sure to trim the wick to the recommended length before lighting the candle.
5. Monitor Burning Time
It’s important to monitor the burning time of candles, especially in hot temperatures. If a candle burns for too long, it can become too hot and melt.
6. Consider the Type of Wax
Some types of wax, such as soy wax, have a lower melting point than others. Consider using candles made from these materials if you live in a hot climate.
By following these tips, you can help protect your candles from melting in hot temperatures and enjoy their fragrance and ambiance all year round.
Alternatives to Traditional Wax Candles for Outdoor Use
There are several alternatives to traditional wax candles that can be used for outdoor lighting without the risk of melting in the sun.
LED Candles
These candles are battery-operated and use LED lights to create a realistic flame effect. They are safe to use outdoors and can be found in a variety of sizes and styles.
Citronella Candles
Citronella candles are made with citronella oil, which repels mosquitoes and other insects. They come in a variety of shapes and sizes and can be used to create a bug-free outdoor atmosphere.
Solar Candles
Solar candles are charged by the sun during the day and automatically turn on at night. They are a sustainable and environmentally friendly alternative to traditional candles.
Oil Lamps
Oil lamps are a traditional lighting option that uses oil and a wick to create a flame. They come in a variety of styles and can be used indoors or outdoors.
When selecting an alternative to traditional wax candles, it is important to consider the intended use and the environment in which they will be used. It is also important to follow all safety guidelines and instructions for use.
Conclusion: Do Candles Melt In The Sun?
In conclusion, while candles can melt in the sun, there are ways to protect them and prevent it from happening. The melting point of a candle is affected by various factors, including the type and density of wax, the size and material of the wick, and the presence of fragrance or color additives.
By taking proper precautions, such as storing candles in a cool, dark place and using alternative candles for outdoor use, you can ensure that your candles last longer and continue to provide the ambiance and atmosphere you desire.
