Candle wax has a memory. This means that your candle remembers where it is burnt up to on that first burn and will only ever burn up to the point it was last extinguished.
Yes! In fact, a candle's first light is called its memory burn. This first impression on your candle sets the boundaries of how it is going to burn until the wick is gone. Getting a great memory burn is essential to stop your candle from creating a tunnel and wasting wax.
When you re-light the wick, the previously-melted area will melt first, and much quicker than the rest of the wax. Wax memory is the area of the candle that melts much quicker than the rest of the candle because it hasn't cooled back the original hardness.
Heat it to 175 degrees F, place the candle on a cookie sheet and pop the candle in the oven for about five minutes. You might need less time for a smaller candle or more time for a larger one. Turn on the oven light so you can keep an eye on the candle and make sure that it doesn't get too warm.
If a candle is not burned for long enough to allow the wax to liquefy or to melt from edge to edge of the container, it will create a “memory ring.” Once a candle has a “memory ring,” it will continue to tunnel for the life of the candle.
Soy wax has a "memory" and helps to avoid the candle from "tunneling" down the center of the container and may cause you not to get the best scent throw. By allowing your soy candle to create its initial memory burn, will help the candle to create a full melt pool of wax, and increase the candle's scent throw.
Solution: Particularly for their first burn, candles are supposed to burn for at least one hour per inch of container diameter. So, if you bought a new candle that is 3 inches in diameter, you should burn your candle for at least 3 hours (though not more than 4 at a time).
Why does the flame flicker on my candle? Any bursts of air that cause your candle flame to dance around also cause your wick to use fuel at an inconsistent pace. The wick is drawing oil from the candle wax as fuel, and a buildup is created within the wick.
If you've ever burned a large candle you may notice the flame flickering and dancing about. A candle topper essentially eliminates this flicker allowing a constant heat source to radiate out over the wax surface allowing for a consistent and even burn.
Candle Wick Meaning
If the wick falls into the melted wax, you can pull it out and attempt to let it regain itself, but if it curls back into the wax, chances are it will self-extinguish and end your spell.
If your candle wick is drowning, that means the size of the wick might be too small for the candle container or the quality of the wick is low. This causes the wick to burn too quickly and “drown” in its own wax pool.
The problem of 'why do homemade candles sink in the middle' has a relatively simple answer and an even simpler fix. Wax sinks when it sets because as the wax cools, it slowly contracts and can leave what I refer to as 'sink holes' in the middle of your candles, but can also present as sunken dips around the wick.
The best way to fix candle tunneling is to prevent it from happening in the first place. And it's very simple, too. To prevent tunneling, all you need to do is burn your candle long enough each time so that the entire top surface of wax is melted. This is especially important the first time you burn your candle!
Today, most candles are made from paraffin wax, a byproduct of petroleum refining. Candles can also be made from microcrystalline wax, beeswax (a byproduct of honey collection), gel (a mixture of polymer and mineral oil), or some plant waxes (generally palm, carnauba, bayberry, or soybean wax).
If you decide to burn just one wick at a time, still do the first burn with all three wicks -- then alternate between wicks for the single burns, so that you keep the level of wax more or less even across the surface of the candle.
Putting the lid on a burning candle deprives the flame of the oxygen it needs to keep going. A candle flame is essentially a continuous combustion reaction between oxygen and hydrocarbons (wax) to form water vapor, carbon dioxide, and heat.
Lids on scented candles protect the wax in your candle from daily dust and grime, and you can use them to prop up your jar and shield your surfaces – so we'll be taking a leaf out of Roja's book and hanging on to ours from now on.
The candle has been burning for too long.
Once the surface is liquid, the inner wax of the candle heats up and begins to evaporate very quickly. The candle is then unstable, causing the flame to burn irregularly. The more the flame moves, the more likely it is to give off soot.
The primary cause of black smoke is an overly long wick. When a candle burns, the wax near the flame melts and the liquid wax is pulled up the wick to feed the flame. If the wick is too long, the balance of heat and fuel will be off. This throws off the chemical reaction and can produce excess soot and smoke.
And you shouldn't forget about the wick after the first time you light it, either. "As the wick burns it becomes black and sooty by nature," Huber explains. "That soot will rise up when you re-light the wick." So to avoid finding yourself in a cloud of black smoke, trim the wick every time you light.
The candle's first burn is an important step to avoid tunneling. Your goal on a first burn is to fully melt the top layer of wax, evenly. If you do not, a “tunnel” will form in the center of the candle, creating a memory ring. Tunneling happens when the first-burn is not a long enough period of time.
Candles don't have a hard expiration date like foods do, but they certainly degrade over time. Eventually, they might become difficult to light or not burn properly. There are two main factors that determine the lifetime of a candle: what kind of wax is used and how the candle is stored.
I don't really smell anything
Also, try burning your candle for a longer period of time, as it may simply need a full melt-pool to diffuse the scent. If none of these things work, it could unfortunately just be a flaw in the candle's creation; the fragrances used may not be potent enough or concentrated enough.
