Jack-o'-Lantern Candle Flame Chemistry

Interactive 2D simulation of a candle flame inside a carved pumpkin, showing the real diffusion-flame zones — dark unburned-vapor core, luminous yellow soot zone, and outer blue combustion mantle — responding to wick exposure, airflow and wax type.

This simulation renders a real candle flame's diffusion-combustion chemistry inside a carved jack-o'-lantern. Wax melts, is drawn up the wick by capillary action, vaporizes, and burns only where the rising fuel vapor meets ambient oxygen — producing three visually distinct zones: a dark/blue core of unburned vapor close to the wick, a luminous yellow zone where glowing soot particles form and burn, and a thin outer blue mantle of complete combustion. Adjust wick exposure, airflow and wax type to see the flame's height, stability and color respond exactly as a real candle would, including flickering and self-extinguishing under a strong draft.

Simulates a candle's diffusion flame inside a carved pumpkin, rendering the dark unburned-vapor core, luminous soot zone, and outer blue combustion mantle as they respond to real airflow and fuel dynamics.
