Enjoy a warm fire for up to 3 hours with a duraflame 4.5lb firelog. This firelog can be used in an open-hearth fireplace indoors or an outdoor fireplace or fire pit. Duraflame fire logs are designed to light quickly with a single match for bright flames in under 5 minutes. Since these firelogs light faster and burn more completely than firewood far less material is consumed and significantly fewer pollutants are emitted. Duraflame firelogs are made from recycled and renewable wood sawdust and agricultural fibers mixed with blends of wax and other combustible renewable materials.
