Wood turns into ash when it is burned due to the combustion process, where organic materials in the wood react with oxygen at high temperatures. During combustion, the cellulose, lignin, and other compounds in the wood break down, releasing gases and heat while leaving behind inorganic minerals and elements that do not combust. The remaining ash consists mainly of these mineral residues, such as calcium, potassium, and magnesium. As a result, the transformation from wood to ash signifies the loss of the combustible organic material.
When litmus paper is dipped in wood ash, it typically turns blue. This is because wood ash is alkaline (basic) in nature, which causes blue litmus paper to remain blue and red litmus paper to turn blue. The alkaline substances in wood ash, such as potassium carbonate, raise the pH of the solution.
Burning produce water vapors, carbon dioxide and ash.
wood
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.
Ash is made from pulverized rock and glass created by volcanic eruptions.

Burning of wood is an oxydation reaction; the products are carbon dioxide, water and ash.
Ash wood is natural and comes from the Ash Tree (Fraxinus).
Maple is stronger than ash. Ash is still a very durable floor.
Burning produce water vapors, carbon dioxide and ash.
ash comes from the middle of the earth. that is why it's called ash it gets burnt a lot in the core of the earth. if you burn wood you get ash
wood
If it's solid ash wood, then it is pretty good and nice!
The amount of ash produced during combustion relative to the amount of fuel fed into the wood pellet stove. Ash content is one indicator of quality for wood pellet fuel. Ash content for wood pellets should be between one and three percent. 

Ash can't
Ash is left over when wood is burned in a fireplace. Ash is the residue that remains after the combustion process, consisting mostly of mineral content from the wood.
