When should I stop burning a candle?

As with most things, knowing when to stop burning your candle is important. This keeps you, and your furniture, safe. When there is approximately 1/2" of wax left in the bottom of your candle it's time to stop burning. It's okay for there to be some wax left over, candles are created with this little buffer of wax. Why do candles have memory? 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. This is why the first burn is the most important. If you do not let your candle burn all the way to the edges, then a memory ring will form.

Why do my candles have sinkholes?

Sinkholes occur naturally from the process of the wax setting up. As wax is heated to melt it into liquid form, the wax expands literally taking up more space as it changes form from solid to liquid. This is the reasoning as to why sink holes can appear in your candles. Consequently, why do you have to cut the wick of a candle? Keeping the candle wick trimmed helps control the amount of melted wax (i.e., fuel) that the candle has access to, which helps limit the amount of soot it creates. The trimmed wick also helps the candle burn more evenly, controlling the soot and prolonging the life of the candle.

Subsequently, how do you fix sunken candles?

Regarding this, why is my candle wick mushrooming? Simply, a mushroom wick occurs when the wax of your candle is unable to burn fast enough to keep up with your chosen wick. This means that the wick starts to absorb the wax which creates a buildup of carbon particles on the wick. Usually a wick that is too big causes more wax to be sent to the flame than it can handle.
