A candle flame wants a steady supply of fuel and air. If either one pulses, it flickers. You do not need a gale. A micro-draught along a floor, a long wick that cannot keep a consistent melt, or a speck of carbon in the pool will do it. “There is no wind” usually means you cannot feel it on your face. The flame can.
Check these first
- Trim to 5mm. A tall wick waves.
- Fish out bits. Wick trimmings in the pool are little rafts of chaos.
- Move it a metre. If the flicker stops, it was air, not the candle.
- Look at the pool. If it is tiny, the wick may be drowning or too small — different problem, still a noisy flame.
A calm flame is teardrop-shaped and quiet. A flickering one is sooting even if you cannot see it yet. Draughts, trim.
If a new jar flickers on a still table with a short wick, take a photo of the flame and write to us. That is a wick issue. If it only flickers in the porch, that is the porch.
