Candle memory is a real phenomenon that impacts the burning pattern of a candle. The first time a candle is lit is called the memory burn, and it determines how the candle will burn until the wick is gone. If the candle is not allowed to melt all the way to the rim during the first burn, it will only ever melt to the point it reached during the first burn. This is why candles sometimes burn down the middle, leaving a ring of hard wax around the edges, a phenomenon known as candle tunneling. Candle tunneling can be avoided by ensuring that the candle's first burn is long enough to reach a full melt pool, or a liquid pool of wax that covers the complete diameter of the candle and reaches the edges of the candle container.

What You'll Learn
Candle memory is a scientific phenomenon
The first lighting of a candle is called a "memory burn". This initial impression determines how the candle will continue to burn until the wick is gone. The candle "remembers" where it was burnt up to on the first burn and will only ever burn up to that point. This is why the first burn is the most important. If you don't let your candle burn all the way to the edges, a "memory ring" will form, and the wax will only burn up to this last point, not past it, which is how tunnelling occurs.
A well-established memory ensures that the candle burns evenly across its surface, preventing the formation of hard wax on the sides. This enhances the aesthetic appeal of the candle and ensures optimal use of the wax, making your candles last longer. An evenly melted pool of wax also allows for a better distribution of fragrance, enhancing the overall sensory experience.
The type of wax a candle is made of makes a difference in how it burns. For example, paraffin wax has a higher melting point compared to soy wax and coconut wax, and it is harder to determine how well it will burn. On the other hand, 100% soy wax has a consistent melting point, and you can easily estimate the time needed to reach a full melt pool. Additionally, soy candles burn cleaner and are easier to clean up if they spill.
Trimming the wick is important when it comes to candle memory. It controls the candle's temperature and flame. If the wick is too long, the flame will be too large, causing sooting and black marks on the jar. If the wick is too short, there may not be enough heat to create a sufficient melt pool, and the wick may end up drowning in wax. The general rule is to trim the wick to approximately 5mm in length and let the candle burn for an hour for every inch of its diameter.

The first burn is crucial
The first burn of a candle is crucial to its performance throughout its lifetime. This is because candles have a ""memory" of how they were burned the first time, and they will continue to burn in the same way each time thereafter. If the first burn does not reach the edges of the candle, a ""memory ring" will form, and the candle will only burn up to this point in subsequent burns, leading to tunnelling. Tunnelling occurs when a candle burns down the middle, leaving a ring of hard wax around the edges, resulting in wasted wax and reduced lifespan.
To prevent tunnelling, it is important to ensure that the first burn of a candle reaches a full melt pool, where the melted wax covers the complete diameter of the candle and reaches the edges of the container. The general rule is to burn a candle for one hour for every inch of its diameter. For example, a candle with a diameter of 5 inches should be burned for at least 5 hours to achieve a full melt pool.
Trimming the wick is also important for achieving a good memory burn. The wick should be trimmed to approximately 5mm in length to control the flame height and burn time. If the wick is too long, it can cause a large flame that can lead to sooting and black marks on the jar. If the wick is too short, there may not be enough heat to create a sufficient melt pool, and the wick may end up drowning in wax. The best wicks for candle memory are braided or knitted and made of natural materials like hemp, as they burn cleaner and help the candle last longer.
Environmental factors, such as draughts, can also affect candle memory. It is recommended to place candles in non-draughty areas to avoid uneven melting. Additionally, the type of wax used in the candle can impact the burning pattern and the formation of a memory ring. For example, paraffin wax has a higher melting point and can be more difficult to work with, while soy wax has a lower melting point and burns cleaner.
By understanding candle memory and taking care during the first burn, candle enthusiasts can ensure their candles burn evenly, last longer, and provide an optimal sensory experience.

Candle tunnelling and how to avoid it
Candle tunnelling is a common problem that occurs when a candle doesn't burn evenly, forming a wax tunnel around the wick. This can be caused by a wick that is too short, creating a small flame that is unable to melt the wax. It can also be caused by the first burn not reaching the edges of the candle, causing the wax to "remember" this burn pattern and continue to burn down instead of across. This results in wasted wax, a shorter burn time, and a diminished scent throw.
To avoid candle tunnelling, it is important to ensure that the wick is trimmed to the appropriate length before lighting the candle. This will create a larger flame that can melt the wax more effectively. It is also crucial to allow the candle to burn until the entire top layer of wax is melted during the first burn. The time required for this will depend on the size of the candle, with smaller candles needing around one hour and larger candles needing up to four hours.
If tunnelling does occur, there are several methods to fix it. One method is to use a hairdryer or heat gun to melt the surface of the candle and create an even layer of wax. Another method is to wrap the candle in tin foil, leaving an opening at the top for the flame, which helps to concentrate the heat and melt the outermost wax. Additionally, ensuring that the candle is placed in a non-draughty area can help prevent tunnelling.

Candle memory impacts the scent throw
Candle memory is a scientific phenomenon that can drastically affect your candle-burning experience. It is the physical memory of how the candle has burned and melted. This memory is imprinted into the candle after the first burn. If maintained correctly, it results in an even melting pool of wax, allowing for better distribution of fragrance, and enhancing the overall sensory experience.
The first burn of a candle is called the memory burn. This initial lighting determines how the candle will burn until the wick is gone. Getting the best memory burn is crucial to prevent candle tunnelling, which occurs when the candle burns down the middle, leaving a ring of hard wax around the edges. This results in wasted wax and reduces the lifespan of the candle. It also diminishes the scent throw as the fragrance oils remain trapped in the unmelted wax.
To achieve a great memory burn, it is important to trim the wicks to the correct length. Wicks are designed to control the temperature and flame of the candle. If the wick is too long, the flame becomes too large, causing sooting and black marks on the jar. Conversely, if the wick is cut too short, there may not be enough heat to create a sufficient melt pool, and the wick may end up drowning in wax. The optimum length for most wicks is between 5mm and 1/4"".
The type of wax also plays a significant role in candle memory. Paraffin wax, for example, has a high melting point, making it challenging to determine how well it will burn. In contrast, soy wax has a lower and more consistent melting point, making it easier to estimate the time needed to reach a full melt pool. Additionally, soy candles burn cleaner and are more environmentally friendly.

Trimming the wick is important
The first time a candle is lit, it is important to let it burn long enough to achieve a full melt pool that reaches the edges of the jar. This will prevent tunnelling, where the candle burns down the middle, leaving a ring of hard wax around the edges. This wastes wax and reduces the lifespan of the candle, as well as diminishing the scent throw.
The type of wick and wax used also affect the candle's memory. Braided or knitted wicks made from natural materials like hemp are preferable, as they burn cleaner and help the candle last longer. Wicks made from twisted material can cause issues. The type of wax will determine the melting point of the candle, which affects how well it burns. For example, paraffin wax has a higher melting point than soy wax or coconut wax, and it is difficult to determine how well it will burn until it is lit.
