Candles are one of the oldest sources of light, and their use has evolved over the years. While candles have traditionally been used for light, they are now often used for decoration and to create a certain ambiance. The drip of a candle is a result of its wax and wick composition, and the lower the melting point of the wax, the more it will drip. This has been a functional aspect of candles for centuries, but it has also become an aesthetic choice in recent times. Candles made from paraffin wax, for example, are known to drip due to the low viscosity of the wax. Today, drip candles are available in various colours and scents, and they can be used to create a unique atmosphere, whether it's a romantic dinner or a relaxing evening at home.

What You'll Learn
The lower the melting point of the wax, the more a candle will drip
The type of wax used in a candle plays a crucial role in determining whether it will drip or not. This is because a candle's wax melting point directly impacts its ability to maintain its shape and withstand heat. Simply put, the lower the melting point of the wax, the more likely it is that the candle will drip.
Wax with a lower melting point tends to melt more quickly, resulting in a shorter burn time. This is because the heat of the flame is sufficient to melt the edges, causing the wax to drip down the sides of the candle. On the other hand, wax with a higher melting point will generally burn more slowly and evenly, making it ideal for candles that need to withstand higher temperatures without melting or dripping.
For example, beeswax has a high melting point of 145 degrees Fahrenheit, making it ideal for candles as it burns at a higher temperature for an extended period. In contrast, soy wax, which is a popular choice for candle makers due to its renewability and biodegradability, has a lower melting point. Low-melt soy wax, in particular, melts at 130 degrees Fahrenheit, which is significantly lower than that of beeswax. This lower melting point means that soy wax candles will begin to melt and release their fragrance at a lower temperature, and they may be more prone to dripping compared to beeswax candles.
The addition of certain substances to the wax can also impact its melting point. For instance, increasing the amount of stearic acid in the wax can raise its melting point, making the candle less prone to dripping. Conversely, mixing wax with a substance that has a lower melting point will result in a candle that is more likely to drip. Ultimately, the melting point of the wax is a critical factor in determining a candle's performance and suitability for different applications.

The thickness of a candle will determine whether it drips
The thickness of a candle plays a crucial role in determining whether it will drip or not. While various factors, such as wax composition and melting point, influence the drippy nature of candles, the thickness or diameter of the candle is a significant factor.
Thicker candles are less likely to drip because the flame is farther from the edges, reducing the chances of the edges melting. The distance between the flame and the edges of the candle is greater in thicker candles, making it less likely that the heat from the flame will cause the wax to melt and drip down the sides. This increased distance helps maintain the structural integrity of the candle, preventing unsightly drips and ensuring a cleaner burn.
On the other hand, thinner candles with a smaller diameter have a shorter distance between the flame and the edges. As a result, the heat from the flame can more easily melt the wax, leading to dripping. The proximity of the flame to the edges of thinner candles makes it challenging for the wax to remain solid, resulting in a higher tendency to drip.
Additionally, the thickness of the candle can impact the overall burn time. Thicker candles tend to burn more slowly and evenly, reducing the likelihood of dripping. In contrast, thinner candles may burn faster and have a higher chance of dripping, as the wax softens and melts more quickly due to the closer proximity to the flame.
It is worth noting that while thickness is a factor, other aspects, such as the type of wax and the presence of additives, also come into play. For example, paraffin wax, commonly used in drip candles, has a low viscosity, causing it to burn quickly and drip. In contrast, candles with higher melting points, achieved through additives like stearic acid or salt, are more likely to be dripless, regardless of their thickness.

Candles can be soaked to prevent dripping
The science behind this lies in the composition of candle wax. Traditionally, candles were made from beeswax, beef tallow, or spermaceti from whales. However, with the development of the chemical industry, stearic acid became a popular alternative due to its low cost and effective burning properties. To improve the brittleness of stearic acid, paraffin, derived from petroleum, is often added. Unfortunately, paraffin has a lower melting point, causing the wax to drip down the sides of the candle.
By soaking candles in salt water, you are effectively changing the composition of the wax. Salt raises the melting point of the wax, making it harder for the heat of the flame to melt the edges. This results in a candle that burns without dripping, creating a cleaner and more elegant aesthetic.
While the salt water method is a clever solution, there are other ways to create dripless candles. One approach is to increase the amount of stearic acid in the wax, as it has a higher melting point. Alternatively, you can design a candle with a larger diameter, placing the edges further away from the flame, reducing the likelihood of dripping. These techniques can be used individually or in combination to create candles that burn brightly without the mess of dripping wax.

Candles can be made dripless by raising their melting point
Another method to increase the melting point of candle wax is to soak the candle in salt. The salt absorbs into the wax, raising its melting point and creating a dripless candle.
The type of wax used also affects the melting point of the candle. Paraffin wax, commonly used in drip candles, has a low viscosity, causing it to burn quickly and drip. In contrast, beeswax candles are known to burn slowly and are less likely to drip.
Additionally, the thickness of the candle plays a role in preventing dripping. A thicker candle has a lower likelihood of the flame melting the edges, resulting in a dripless candle.
By understanding the factors that influence the melting point of candles, such as wax composition and thickness, and by employing techniques like increasing stearic acid content or soaking in salt, it is possible to create dripless candles that provide a clean and mess-free burning experience.

Candles with a rustic aesthetic are more likely to drip
The "drip" effect of candles was not always an aesthetic choice but rather a function of a candle's wax and wick composition. All taper candles, to some extent, do drip. However, the "drip" has now become a conscious style choice, with candles being designed to drip.
The trend of using bottles as candle holders first emerged during WWII in Italy. At the time, the country was facing extreme scarcity and it was more economical to repurpose wine bottles as candle holders. The unique design of Chianti bottles, with their broad base and straw basket, prevented wax from pooling on the table. This design dates back to the 14th century and was the result of a manufacturing mishap that was later corrected by glassmakers.
Today, drip candles are often made from paraffin wax, which has a low viscosity, causing the wax to drip instead of burning away. These candles burn quickly and require close supervision to prevent accidents.
Some people prefer the rustic aesthetic of candle wax dripping down, while others opt for dripless candles to maintain a clean look. Ultimately, the choice between drippy and dripless candles depends on personal preference and the desired ambiance.

Frequently asked questions
Drip candles are candles that are made from paraffin wax, which has a low viscosity and melting point. This causes the wax to drip instead of burning away.
The trend of using wine bottles as candle holders first started during WWII in Italy, where people repurposed wine bottles due to the scarcity of resources. The unique design of Chianti bottles, with their broad base and straw basket, prevented wax from pooling on the table.
Drip candles can be purchased from various retailers such as Amazon, Urban Outfitters, Candle Stock, and Hobby Lobby.
To make your own candles drip, you can soak them in water with salt for a couple of hours. The salt will absorb into the wax and raise its melting point, causing it to drip.
