Cold throw hints at character before ignition, while hot throw defines real impact once a full melt pool forms. Room size, ceiling height, and air currents reshape perception. Map these factors first, then combine candles so overlapping radii complement rather than clash, building depth without muddiness.
Burn length depends on wick thickness, wax blend, dye and fragrance load, and vessel geometry. Thicker wicks accelerate consumption and heat; smaller ones prolong but risk tunneling. Balance sets by matching rates, ensuring each candle reaches a clean melt pool while collectively sustaining hours-long ambiance.
