Ceramic oil burner always place the ceramic oil burner on a heatproof mat. Ensure there is sufficient water in the container above the burner. Use good-quality tealights. 

Never leave unattended when lit, and keep away from curtains. If the flame becomes dangerous, extinguish with a damp cloth. Keep out of reach of children. Oil burners are also great to use with Fragrance Oils and Wax Melts.
