We recommend that the first time you burn your Marie & Grace candle, you burn it for around 3 hours to make sure it burns perfectly every time you use it. We also recommend you trim your wick to about 1/4 inch before every burn. Make sure you keep your burning candle away from flammable materials and substances, out of reach of children, and on a flat and stable surface while it is lit. We recommend that you place the lid on your candle between burns as well.
