WebOct 18, 2024 · Oct 18, 2024 at 7:25. 2. @jnovacho Bulk graphite won't burn well even at its autoignition temperature (thin sheets might). And graphite crucibles are often used in environments where the hottest parts are not in contact with much oxygen. If the rate of burning is very slow, it may not matter much in a bulk object. – matt_black.
