What is the best kind of wood to use?
Use only well-seasoned hardwood (oak, hickory). If you have to burn softwoods (fir, cedar), be certain they are well seasoned. Look for split, dry wood that has been stacked for up to a year. Loose bark and cracks in the ends are signs of seasoned wood. One easy way to tell is: if it drops its leaves, it’s better to burn than if it stays green all year, i.e. evergreens.
