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.
Wood ash has a high pH, usually around 10 to 12, says Chelsea McKinley, plant health specialist at the U.S. Botanic Garden in Washington, D.C. Most plants prefer a soil pH of around 6.5.

Ash is the solid remnants of fires. [1] Specifically, ash refers to all non-aqueous, non-gaseous residues that remain after something burns.In analytical chemistry, to analyse the mineral and metal content of chemical samples, ash is the non-gaseous, non-liquid residue after complete combustion.
Wood ash is around 1% the mass of the original wood, though some kinds of straw leave ash at a much higher percentage of the original weight. [9] Usually a large quantity of wood or straw is necessary to produce the ash. The ash is then put through a sieve to eliminate the excess clumps from the ash. At this point, artists can process the ash ...
Zanthoxylum parvum, known vernacularly as Shinners' tickletongue and small prickly-ash is considered by some botanists to be an isolated and aberrant population of Zanthoxylum americanum. Originally described by Scottish botanist Philip Miller in 1768, [ 4 ] Zanthoxylum americanum is type species of the wide-ranging genus Zanthoxylum in the ...
