Research: The terms hardwood and softwood refer to the density of wood, how hard it is, and how much weight it has. A dense hardwood like oak or maple has high energy content per cord, so it releases more heat and produces long-lasting embers. Hardwood is the best type of firewood for long lasting warmth and cooking but can sometimes be hard to ignite and split…show more content…
Fuel is a less combustible material that burns slow and steady once lit, like tree trunks, coal and oil. To start a fire, first the tinder is lit on fire. Then the kindling on top of it catches fire.
