The burning of wood results in about 6–10% ashes on average. [2] The residue ash of 0.43 and 1.82 percent of the original mass of burned wood (assuming dry basis, meaning that H 2 O is driven off) is produced for certain woods if it is pyrolized until all volatiles disappear and it is burned at 350 °C (662 °F) for 8 hours.
Thermally modified wood is engineered wood that has been modified by a controlled pyrolysis process of wood being heated to (> 180 °C) in an oxygen free atmosphere. This process changes to the chemical structures of wood's cell wall components lignin , cellulose and hemicellulose which decreases its hygroscopy and thus increases dimensional ...
White ash is one of the most used trees for everyday purposes and, to keep up with high demand, is cultivated almost everywhere possible. The wood is white and quite dense (within 20% of 670 kg/m 3), [24] strong, and straight-grained. Its species produces an ideal, atypical dominant excurrent structured crown.

The wood of old ash trees in general are valued for firewood due to their fine grain and brittleness.
