Q. What happens to wood when it burns?
Wood is made of fiber (cellulose) and minerals (metals). When wood is burned, oxygen and other elements in the air (mainly carbon, hydrogen and oxygen) react to form carbon dioxide that is released into the atmosphere, while the minerals turn into ashes. Thus the carbon is left to turn into charcoal.

Q. What substances are formed when wood burns?
The burning of wood leads to the formation of new substances like ash(carbon), carbon dioxide gas, water vapour, heat and light.
Q. What is the energy changes taking place when wood is burnt?
In the case of burning wood, stored potential energy (in the form of chemical energy) in the log is released due to heating by other excited atoms. This chemical reaction is called combustion and requires oxygen. Combustion changes the potential chemical energy into kinetic energy in the form of heat.
Q. What property of wood would you need to know to predict how fast the wood would start to burn?
Answer: The chemical property of combustion.
Q. At what temp does wood catch fire?
Firstly, at about 320 degrees Fahrenheit up to about 500 degrees, the wood will start to burn and you can see it change in a way that can’t be reversed (char marks, cracking, shrinking, etc.) and at some point (anywhere above about 390 degrees) the wood will catch fire.
Q. How long does it take for wood to catch fire?
When dry or “seasoned” firewood has a moisture content at or below 20%, its ready to burn. As for how long it takes to get there? Well, the answer to that question is: It depends. Most wood is seasoned within 6 – 9 months but there are so many variables that affect the time it takes to dry firewood.
Q. How long does wood have to dry before burning?
It’s a year-round task because firewood requires anywhere from six months to two years dry out. Late winter and early spring are ideal times to cut and store wood for the following year. It allows wood to dry over the summer months, seasoning in time for colder weather.
Q. How long does pine need to dry before burning?
In general, pine and other softwoods require around 6 to 12 months to season, while hardwoods such as oak require a year to 2 years.
Q. Why is pine not good for burning?
Pine creates creosote. In fact, all wood does. But opponents of burning pine believe that it creates more creosote merely because it contains a lot of pitch. Similar to a hot shower, when the heated particles contact the cooler flue, the vapor solidifies into a layer of creosote.
Q. How long after cutting a tree does it burn?
When a living tree is cut down, the timber needs to age or “season” for a minimum of six to nine months before burning. Freshly cut wood, called green wood, is loaded with sap (mostly water) and needs to dry out first. It’s hard to light and once you get it going, it burns very efficiently and smokes horribly.
Q. Should I let logs dry before milling?
Summary: Logs should be milled for drying as soon as possible, and the ends should be sealed as soon as they are felled. Logs can be sawn for grade, quarter sawn, or flitch cut. They should be milled about 1/4″ over than your intended final thickness.
Q. Does cutting wet wood dull a chainsaw?
Does Cutting Wet Wood Dull a Chainsaw? Using your chainsaw to cut through wet wood will not dull the chain any faster than using it for other types of wood.
