Charring is a chemical process of incomplete combustion of certain solids when subjected to high heat. Heat distillation removes water vapour and volatile organic compounds (syngas) from the matrix. The residual black carbon material is char, as distinguished from the lighter colored ash. By the action of heat, charring removes hydrogen and oxygen from the solid, so that the remaining char is composed primarily of carbon. Polymers like thermoset, or most solid organic compounds like wood or biological tissue, exhibit charring behaviour.

| - الاحتراق الناقص عملية كيميائية وهي احتراق غير كامل لبعض المواد الصلبة عند تعرضها لحرارة عالية. حيث يزيل التقطير الحراري بخار الماء والمركبات العضوية المتطايرة من المجموعة وتكون المادة المتبقية من الكربون الأسود في شكل مميز عن الرماد ذي اللون الفاتح. وبتأثير الحرارة، يزيل هذا الاحتراق الهيدروجين والأكسجين من المادة الصلبة ويتبقى الكربون.

- Carbonização é um processo químico de combustão incompleta de determinados sólidos quando submetidos ao calor elevado. O produto desta reação química é chamado de carvão. Pela ação do calor, a carbonização remove hidrogênio e oxigênio do sólido, de modo que a matéria restante é composta principalmente de carbono. Polímeros, como termofixos ou mais sólido compostos orgânicos como madeira ou tecido biológico, são exemplos de materiais que podem ser carbonizados. (pt)

- Charring is a chemical process of incomplete combustion of certain solids when subjected to high heat. Heat distillation removes water vapour and volatile organic compounds (syngas) from the matrix. The residual black carbon material is char, as distinguished from the lighter colored ash. By the action of heat, charring removes hydrogen and oxygen from the solid, so that the remaining char is composed primarily of carbon. Polymers like thermoset, or most solid organic compounds like wood or biological tissue, exhibit charring behaviour. Charring means partially burning so as to blacken the surface. Charring can result from naturally occurring processes like fire; it is also a deliberate and controlled reaction used in the manufacturing of certain products. The mechanism of charring is part of the normal burning of certain solid fuels like wood. During normal combustion, the volatile compounds created by charring are consumed at the flames within the fire or released to the atmosphere, while combustion of char can be seen as glowing red coals or embers which burn without the presence of flames.

Polímeros, como termofixos ou mais sólido compostos orgânicos como madeira ou tecido biológico, são exemplos de materiais que podem ser carbonizados. Carbonização é o resultado de processos naturais como o fogo, mas também uma reação deliberada e controlada utilizada na fabricação de certos produtos, como o alcatrão e o Licor Pirolenhoso. O mecanismo de carbonização é parte da queima normal de certos combustíveis sólidos tais como madeira. Durante a combustão normal, os compostos voláteis criados por carbonização e pirólise são consumidos para as chamas dentro do fogo, enquanto combustão de carvão pode ser visto como carvões de incandescência vermelhos ou brasas que queimam sem a presença de chamas.
