Question: Is oak wood better than mesquite wood to burn in a fireplace? If so- why? If not- why not? Answer: We don't have mesquite here in the NE area of the US- so some of its' qualities are unknown to me.Oak has a few things going for it. 1. It does not spit embers like many softwoods 2.It has a high density and BTU content- which means a good burn time from each log. 3. It ha a good"coaling" quality- which means that the red-hot embers remain long after the flame goes out.
