First Burn: Burn candle for 2 hrs for the 1st burn. Allowing a full wax pool ensures an even burn and maximum scent throw. 4 hr Maximum Per Burn: Excessive heat produced during long burn times cause essential oils to burn out faster. Best Before Date: Plant-based essential oils perform best when used within 6 months from the batch production date. Wick Trim: To provide the cleanest burn possible, trim your cotton wick. Half Inch Rule: Discontinue use of the candle when there is ½ inch of wax left to prevent damage to surfaces or the container. Safety: Never leave a burning candle unattended.
