Capable of being converted into carbon or a carbon compound through heating or chemical treatment.
From carbonize + -able (suffix meaning 'capable of' or 'worthy of'). The -able suffix comes from Latin and French, indicating potential or possibility.
Almost any organic material—wood, bone, sugar—is carbonizable, which is why medieval alchemists obsessed over turning things to ash and carbon; they were accidentally discovering the basics of modern chemistry.
