How do you increase the flame of a candle? Keep wicks trimmed. A trimmed wick will give you a nice bright flame. A long or a crooked wick can result in uneven burning, which can lead to bursts of high flames or smoking. Wicks should be about 1/4-inch high for best burning; don’t trim them lower than that.
Why is my candle flame so small? Candle flames that are small are usually because it’s not burning enough fuel and this causes a lower flame height. These issues can be fixed by adjusting the wick and/or clearing excess wax.
How do you make flames grow? Stack the new firewood with a lot of space between the logs to get proper ventilation. Frequently add more tinder and kindling to the open spaces between your logs. Blow on you fire. This is especially useful when you are just lighting the fire, to make it bigger.
How do you fix a low flame on a candle? If the flame remains weak, blow out the candle and pour the wax it melted onto a paper plate. Once it cools, dispose of the wax and plate in the trash. Alternatively, you can soak up the liquid wax with a paper towel or cotton swab (after the candle is extinguished, of course).
