After extinguishing the flame, if necessary centre the wick in the liquid wax. To enjoy best diffusion and burning, you need to burn the candle 2 or 3 hours at a time maximum, or until the whole top of the candle becomes liquid. It is essential to cut the wick short (1/4 inch) before relighting the candle to avoid unnecessary smoke. Do not place the candle in a wind draught or directly on a glass, wooden or marble surface. Never leave a burning candle unattended. Never move or tip a burning candle. Always burn on a flat and stable surface. Keep out of reach of children and pets. To reuse your glass vessel as a container, soak in warm, soapy water to clean. Not suitable for use with food. Keep this information for future reference.
