Which brand of candles burn the fastest?

Answer 1

There must be thousands of different brands of candles. Maybe you meant to ask what type, like paraffin or Beeswax?

From my experience with candles, the ones that burn fastest are narrow paraffin candles, especially cheap ones. Birthday cake candles are a good example. A narrow candle has a smaller liquid pool at the top, causing the wick to burn down quicker, and also allows a lot of the wax to run down the sides of the candle, which starves the wick of wax and consumes it faster. Also, the size of the flame is not necessarily larger on a bigger candle. Flame size is dependent upon the size of the wick, and the liquid wax's ability to saturate and climb it. The wick only begins to shorten when there is not enough wax available to keep the wick saturated. A thinner candle generally has a higher Flame/mass ratio, allowing the wax to be consumed faster.

Thinner candles, such as birthday candles or emergency candles, typically burn faster than thicker candles like pillar candles or jar candles. The materials used to make the candle, such as paraffin or soy wax, can also influence burn time.
