What exactly is sweet gum firewood?
Sweet gum is a hardwood that burns quite intensely and quickly. The tree thrives in a moderate, humid climate and usually exists in the Southeastern United States.
It is also a valuable tree for the lumber business, useful in making furniture and decorative items.

Let’s look at some of the properties of sweet gum firewood.
A Cord of Split Firewood.
Sweet gum requires approximately a year to thoroughly season before using it as firewood. Also, the sweet gum firewood might contract up to 15% during seasoning. It makes it more difficult to split the wood, and it also impacts the wood’s general appearance.
Although Sweetgum does not create a lot of creosote, you still need to clean your chimney occasionally. Notably, sweet gum firewood has a relatively high moisture content for hardwood while it is green. It also has significant resin content.

With a heat production of 20.6 to 21.3 million BTUs /cord, sweet gum ranks at the middle of the heat output range.
Also, although its a hardwood, you should consider burning it with better-grade firewood like oak. Primarily, this is to sustain its burning since sweet gum burns quickly. Besides, sweet gum burns with a lot of ash.

The main difficulty with using sweet gum as firewood is breaking it. Primarily, this is due to the warp that results when the wood dries out. It causes the fibers to intertwine, making them harder to cut through.
Thus, it would be best to split the logs while it’s still greenwood. Else, the task will become challenging due to moisture loss when it dries.
Huge dark smoke rose from a chimney.
When you properly season and dry sweet gum firewood, it will yield low smoke while burning. However, unseasoned sweet gum gives a lot of smoke.
Also, remember that even after it’s completely dry, sweet gum still sparks, albeit minimally. Therefore, you should employ a fireplace glass screen in front of your stove to prevent these sparks from being hazardous.
Sweet gum ignites quickly. Irrespective of this property, sweet gum yields low-quality coal and burns for short periods. Hence, it would be best to burn it alongside other hardwood species like Beechwood, Oak, or Hickory firewood to sustain its burning period.
The smell of sweet gum is not intense or distinctive. The firewood may also develop a musty smell if left moist for a long time.
Varieties of Sweet Gum Firewood
