When purchasing, cutting, or collecting firewood, it is good to be aware of the difference between hardwood and softwood. Both hardwood and softwood have similar energy contents by mass, but not by volume. In other words, a piece of hardwood would usually be heavier and have more available energy than the same sized piece of softwood.
Softwood is wood from gymnosperm trees such as conifers. The term is opposed to hardwood , which is the wood from angiosperm trees. The main differences between hardwoods and softwoods is that the softwoods completely lack vessels (pores). [ 1 ]
Cheaper "hardwood" doors, for instance, now consist of a thin veneer bonded to a core of softwood, plywood or medium-density fibreboard (MDF). Hardwoods may be used in a variety of objects, but are most frequently seen in furniture or musical instruments because of their density which adds to durability, appearance, and performance.

The well-known balsa (a hardwood) is actually softer than any commercial softwood. Conversely, some softwoods (e.g. yew ) are harder than many hardwoods. There is a strong relationship between the properties of wood and the properties of the particular tree that yielded it, at least for certain species.
Wood ash from a campfire. Wood ash is the powdery residue remaining after the combustion of wood, such as burning wood in a fireplace, bonfire, or an industrial power plant.It is largely composed of calcium compounds, along with other non-combustible trace elements present in the wood, and has been used for many purposes throughout history.
Softwood will burn faster than a hardwood does. It does not require very hot temperature to burn as do the hardwoods. [11] Light-coloured hardwoods such as sycamore, basswood, beech and birch are most commonly used, as their fine grain is not obtrusive. However, other woods, such as maple, pine or oak, are also used.
A report [9] in 2010 concluded that burning biomass such as wood pellets or wood chips releases a large amount of CO 2 into the air, creating a "carbon debt" that is not retired for 20–25 years and after which there is a net benefit. [9]
