A quality hand-poured candle should give you somewhere between 40 and 60 hours of burn time. Most people get considerably less than that, not because the candle is poor, but because of one common mistake made the very first time it is lit. Once you know it, you cannot unknow it.
These are the things we tell every customer who buys a candle from us. They apply to soy wax, beeswax, paraffin, coconut wax — any candle you are going to spend real money on.
The First Burn Is the Most Important
Candle wax has something called "memory." This sounds like marketing language, but it describes a real and observable thing. The first time you burn a candle, the wax melts out to a certain diameter and then solidifies. Every subsequent burn follows the same path. If your first burn only melts the wax directly around the wick, you end up with a tunnel that goes straight down, leaving a thick ring of unused wax around the outside that will never melt.
The fix is simple: the first time you light a candle, let it burn until the entire surface has become liquid. For a typical 20cl candle in a glass vessel, that takes roughly two hours. For a wider candle, it might take three. It feels like a long time, but this single step determines how the candle will burn for the rest of its life.
Trim the Wick Before Every Burn
A wick that is too long produces a larger flame than the wax can support, which leads to black soot on the inside of the vessel, a flickering unstable burn, and uneven consumption. The wick should be trimmed to about 5mm before every use.
You do not need a wick trimmer, though they are useful and satisfying to use. Small scissors or nail scissors do the job perfectly well. If you notice mushrooming at the tip of the wick, a small carbon bloom, trim that off before relighting.
Trimming takes ten seconds and genuinely extends the life of a candle by 20 to 30 percent. It also keeps the vessel clean, which matters if it is a nice one.
Keep Burns Between Two and Four Hours
Burning a candle for more than four hours at a time causes the wick to move, the fragrance to off-gas too quickly, and the vessel to overheat. You get less scent throw in the end, the fragrance dissipates faster, and the candle does not smell as good in its final third.
Two to four hours is the sweet spot. Burn it while you cook and eat dinner. Burn it for a long bath. Then snuff it out. The accumulated effect of several shorter burns gets you far more fragrance over the candle's lifetime than one long marathon session.
How to Put a Candle Out
Blowing a candle out sends a plume of smoke into the room and often deposits a bit of ash onto the surface of the wax. Over time, that affects the fragrance. A snuffer is the proper tool, but again not essential. You can dip the wick gently into the liquid wax using a cocktail stick or toothpick, then straighten it back up. This extinguishes without smoke and coats the wick in wax, which makes relighting easier.
If you do blow it out, make sure the wick is centred in the pool of liquid wax before the wax sets. A wick that drifts to one side produces an uneven burn.
Where You Place a Candle Matters
Draughts and airflow cause candles to burn faster and unevenly. An open window, a fan, or simply being near a doorway will make one side of the candle melt faster than the other. Try to burn candles away from direct airflow.
On the surface question: candles get hot. The base of a glass candle vessel will get warm enough to leave a mark on certain wood finishes and lacquered surfaces. Use a candle plate, a small tray, or even a folded piece of card underneath. The ring marks on wooden furniture are almost always from condensation, but the heat mark risk is real with prolonged burns.
Getting the Most From Soy Wax Specifically
Our candles are hand-poured in soy wax, which behaves a little differently from paraffin. Soy wax burns more slowly and at a lower temperature, which is why you get longer burn times and a cleaner scent. However, it is more sensitive to temperature changes during storage. Keep soy candles away from direct sunlight, which can cause fading and uneven crystallisation on the surface. A cloudy or lumpy surface on soy wax is called frosting and is completely natural — it does not affect performance at all, it is just the nature of the material.
Also: soy wax candles have a "cure" time. The fragrance continues to bond with the wax for several weeks after pouring. If you have bought a candle and it seems faint on the first burn, give it a bit of time. Many of our customers report that candles smell stronger after they have had a few weeks to settle.
When There Is an Inch of Wax Left
Stop burning when there is roughly 1cm of wax remaining at the bottom of the vessel. Below that point, the vessel gets too hot, which can cause cracking in glass containers and, in extreme cases, heat the surface it is resting on. It is also where you get the most carbon deposits.
The good news: once the candle is finished, clean the vessel with hot water and a bit of washing-up liquid. What is left after burning is usually a perfectly beautiful ceramic or glass vessel that works brilliantly as a bud vase, a pen pot, or a small planter for succulents. Our customers reuse them constantly. It is one of the reasons we choose vessels that are worth keeping.
