WoodWick Large Hourglass Candle fills the space with sophisticated scented and a soft crackle for a natural wooden wick that crackles as it burns. How to use: 1. Allow wax to poolYou will experience the best burn results when the candle remains lit for 3-4 hours. Make sure that the wax melts to the edge of the candle before extinguishing. Allowing the wax to pool will discourage tunnelling or leaving wax on the sides of the vessel. 2. Keep the candle within sight and away from drafts Always place the candle on a flat, heat resistant surface and make sure to keep the candle away from children, pets, flammable materials, and other heat resources. 3. Never move or handle the candle while it's burning or while the wax is hot To be safe, only move your candle once the lame is extinguished and the wax has completely cooled. 4. Know when to trim the wick The wick should be trimmed to 6mm before each use. 5. Know when to say goodbye When there is approximately 6mm if wax remaining, it is time to stop using your candle.
