Why avoid carbonization phenomenon when wet digestion

When wet digestion, it is necessary to avoid carbonization phenomenon, because carbonization phenomenon, after adding mixed acid, it is easy to explode.

Wet digestion is an alternative to dry digestion for the preparation of samples for total elemental analysis by decomposing and oxidizing organic substances in soil or plant samples with inorganic strong acids and/or strong oxidant solutions, so that the components to be measured are transformed into measurable forms.
