let's start with the basics that apply to all wood wick candles, including ours!
1. on the first burn, allow the wax to fully melt to the edge of the can, both on the first burn and consecutive ones! (2-3 hours max) do this by breaking off the TOP black bits of the wick with your fingers, or use nail clippers (weird but it works!) to shorten the wick to be about 1/8″ – 3/16″.
2. on every new burn, re-trim the wick to 1/8." the shorter height allows the wax to capillary up the wick to feed the flame properly. always allow enough time for the wax to melt to edge of can before blowing out.
3. do NOT burn the candle for longer than 3-4 hours at a time. it's time for a new candle when there is 1/4" wax remaining.
