Before lighting for the first time and for each subsequent burn, trim wick to 5mm. This will ensure a cleaner, brighter burn. Wick trimmers sold seperately. Burn until the wax pool reaches the edge of the glass to ensure your candle always burn evenly. Do not burn for more than three hours at a time. Discontinue burning when you have 1cm or less of wax in your candle. Always place your candle on a heat resistant surface. Do not leave your candle unattended and keep away from children, curtains and pets. Do not touch your burning candle or move while wax is liquid. Avoid using in drafty areas, near an open window, air duct or fan.
