We recommend trimming the wick to a 1/4 inch, to reduce debris in the candle for a safer burn. Burn the candle for no more than 4 hours at a time, and cease use when there is 1/2 an inch of wax remaining in the vessel.
Repurpose the vessel by freezing the candle for a few hours before removing and discarding any remaining wax (this ensures an easy removal). Clean with soap and warm water, and enjoy your new and functional decor (display on a bathroom vanity, or use as a trinket or plant holder).
