Burn time is primarily influenced by candle size, wax type, and wick thickness. Larger candles tend to have longer burn times, with higher-quality waxes and thicker wicks contributing to extended combustion durations.

For optimal performance, trim candle wicks to approximately 1/4 inch before each lighting. This ensures a stable flame, prevents soot buildup, and maximizes the candle's lifespan.

Glass containers are ideal for enclosed spaces, as they contain the flame and limit scent diffusion. Ceramic containers maintain heat well, while metal containers provide durability and a contemporary aesthetic.

Tunneling occurs when a candle burns down the center, leaving a thick layer of wax on the sides. To avoid this, burn your candle at least two hours each time you light it, creating an even melt pool that extends to the edges.
