Density is onlv one consideration, however, since some woods are difficult or almost impossible to split. Others are difficult to dry and store. Some have unpleasant odors and some just don't burn well. Personal preferences plays an important part in choice of firewood. Oaks, hickories and ash are usually preferred.
Live oak is one ofthe heayier woods.
It burns well, stores well and is widely distributed, but it is somewhat difficult to split. Red oaks are plentiful and easy to split. They often have a sour odor when freshly cut. Ash has often been called the best firewood. Blackjack and other scrub oaks are preferred by some almost to the exclusion of other woods.
