The article is focused on the creation of a protocol for the analytical characterization of fire-setting in different types of rock. A set of experiments of heating and cooling have been carried out on different kind of rocks under various conditions and durations in order to record changes in the structures and composition of the samples. This study was set to support the solution of issues in the case of...
