Burning {ashing}| requires 400 C to 700 C in furnace, followed by dissolving sample in hydrochloric acid. Lead, zinc, cobalt, antimony, chromium, molybdenum, strontium, and iron evaporate at 500 C. Low-temperature ashing uses microwaves to make oxygen radicals and oxidizes sample at less than 100 C. Oxygen combustion can find carbon and hydrogen amounts. Ascarite absorbs carbon dioxide. Dehydrite absorbs water.
