Every jar that leaves the studio says 45+ hours on it, and we mean it. But burn time is not something a candle has — it is something a candle and its owner make together. The wax, the wick and the cure are our half of the bargain. The other half happens on your shelf, and most of it is decided in the first three hours.
The first burn is the mould
Soy wax has memory. Wherever the melt pool reaches on the first burn becomes the outer edge of every burn after it — the wax remembers its first shape and keeps returning to it, the way a path forms across a lawn.
So the first evening matters more than any other. Light the candle when you have three unhurried hours, and let it burn until the pool of liquid wax reaches the glass all the way round. Cut that first burn short and the candle learns a smaller circle: every future burn tunnels down the same narrow hole, leaving a thick collar of wax that will never melt. That collar is hours of scent you paid for, standing on the sidelines.
Three hours, once. It is the cheapest thing you will ever do for a candle.
Five millimetres, every time
Between burns, the wick keeps a little history — a bloom of carbon at its tip from the last evening. Left alone, that bloom makes tomorrow’s flame tall, restless and smoky. It burns wax faster than the pool can feed it, soots the glass, and turns a 45-hour candle into a 35-hour one with dirty windows.
The fix takes five seconds. Before each light, pinch or snip the wick back to 5 mm — about the height of a grain of rice standing on end. A trimmed wick burns low, bright and clean, sips instead of gulps, and keeps the flame at the height the wick was sized for. If your flame ever dances above three centimetres, it is not enthusiasm — it is a wick asking for a haircut.
Draughts, sittings, and letting soy rest
A flame that flickers is a flame burning unevenly, melting one side of the jar faster than the other. Corners beat windowsills; still rooms beat hallways. And soy likes a rest — three to four hour sittings, then a pause, beat an all-day burn. The wax re-levels as it cools, the wick stays centred, and the scent stays layered instead of flattening into one warm blur.
The last centimetre is a beginning
When one centimetre of wax remains, stop. Below that line the flame sits too close to the base and the glass runs hotter than it should — the last centimetre is a safety margin, not an encore.
It is also your cue. That finished jar is the start of the next candle: drop it in a postbox with the freepost label from your order, and £16 brings it home refilled with any scent on the shelf, re-wicked, re-cured, ready for another first burn. Our record holder is on her ninth refill of the same jar. The glass does not mind. The glass was built for this.
The boring-but-important bit: never leave a burning candle unattended, keep it on a heat-proof surface away from anything that hangs or flutters, and out of reach of pets and small hands. The full guide lives in candle care — it prints nicely, if you are the fridge-door type.
