ABOUT / プロフィール
Ash is the solid remnants of fires. 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. Ashes as the end product of incomplete combustion are mostly mineral, but usually still contain an amount of combustible organic or other oxidizable residues. The best-known type of ash is wood ash, as a product of wood combustion in campfires, fireplaces, etc. The darker the wood ashes, the higher the content of remaining charcoal from incomplete combustion. The ashes are of different types. Some ashes contain natural compounds that make soil fertile. Others have chemical compounds that can be toxic but may break up in soil from chemical changes and microorganism activity. Like soap, ash is also a disinfecting agent (alkaline). The World Health Organization recommends ash or sand as alternative for handwashing when soap is not available. Before industrialization, ash soaked in water was the primary means of obtaining potash.

Ashは火の固い残りかすです。具体的には、ashは何かが燃えた後に残るすべての非水性、非気体の残留物を指します。分析化学では、化学サンプルのミネラルと金属含有量を分析するために、ashは完全燃焼後の非気体、非液体の残留物です。不完全燃焼の最終生成物としてのashesはほとんどがミネラルですが、通常、燃焼可能な有機物またはその他の酸化可能な残留物のある量を含んでいます。最も有名なashの種類は木灰で、キャンプファイヤーや暖炉などでの木の燃焼の生成物です。木灰が暗いほど、不完全燃焼による残存する炭の含有量が多くなります。ashesはさまざまな種類があります。土壌を肥沃にする天然化合物を含むashesもあります。一方、有毒である可能性のある化学物質を含むものもありますが、化学変化と微生物活動により土壌中で分解される可能性があります。石けんと同様に、ashは消毒剤（アルカリ性）でもあります。世界保健機関は、石けんが利用できない場合の手洗いの代替手段としてashまたは砂を推奨しています。工業化以前は、水に浸したashがカリを得るための主な手段でした。
