The issue of elements remaining in the barrel after firing is crucial both for the safe use of munition, and its reliability. These elements maybe categorized as being part of a metal case or a projectile (for example, fragments of broken connectors between a metal band and a projectile), or those associated with a propelling charge (like unburnt propellant grains). Both groups are undesirable and reflect the ammunition improper work. During own shooting tests of a 120 mm mortar ammunition the problem of unburnt elements remaining in the barrel occurred. The collected material was tested using one of the thermal analysis techniques - Differential Scanning Calorimetry - to characterize and to identify the tested sample.
