What does carbonised mean?
Carbonised means converted into carbon or a carbon-rich residue, usually by heating a substance while limiting its access to oxygen. The term is especially common in British English, whereas US English normally uses carbonized. Carbonised remains may be studied in archaeology, while carbonised fibres and particles occur in materials science and environmental research. The word is more specific than simply burnt: burning in abundant oxygen generally produces ash, whereas carbonisation produces a dark, carbon-rich solid. Carbonised can function as an adjective, as in carbonised remains, or as a past-tense and past-participle verb form. The related noun carbonisation names the process. Although charred is often a close synonym in general use, carbonised tends to carry a more technical or scientific tone and suggests deliberate conversion into carbon rather than mere surface blackening.
Having been converted into carbon or a carbon-rich residue, especially through heating with limited oxygen.
"The laboratory tested samples of carbonised plant material."
The adjective is more technical than charred in scientific and archaeological writing.
To convert a substance into carbon or a carbon-rich residue by heating it with limited oxygen.
"The researchers carbonised the sample before analysis."
This is the British past-tense and past-participle form of carbonise; the US form is carbonized.
Carbonisation depends on oxygen deprivation: rather than disappearing into ash, the material leaves behind a carbon-rich skeleton.

Where does carbonised come from?
Carbonised is formed from carbon and the verb-forming suffix -ise, which also gives the corresponding British noun carbonisation. Carbon comes through French from the Latin word carbo, meaning coal or charcoal. The English verb developed during the modern period for the treatment of organic substances in limited oxygen, and cognate forms occur in other European languages, including the American variant carbonized.
