It’s not just about size. These oversized candles are so stunning. And, with four flames burning at once, are just the thing for scenting larger rooms. How to Get the Perfect Burn: Prior to each lighting, trim the wick to 1/4” for a clean and smoke free burn. On your first light, allow the entire surface of wax to melt — Minimum of 3 hours. There will be some “wax wall hanging,” but that’s normal. After the first burn with wax melted to the edge of candle vessel, never let it burn for more than 4 hours. Discontinue use when there is only 1/4" wax left in the vessel. Ensure the wick is centered. After each burn, adjust the wick while the wax is still molten.
