Always Trim Your Wick to 1/4" Before Candle is Lit Each Time to Avoid Any Soot. Burn Candle so Wax Pool Reaches the Jar Edge Each Time to Prevent Wax Tunneling. Burn Candle No More Than 4 Hours at a Time and Do Not Burn Candle with Less Than a 1/2" of Wax Remaining. Keep Candle Away from Fans, Open Windows, Hot Surfaces, Children, and Pets. Never Leave a Burning Candle Unattended.
