TNT is prone to exudation of dinitrotoluenes and other isomers of trinitrotoluene when projectiles containing TNT are stored at higher temperatures in warmer climates. Exudation of impurities leads to formation of pores and cracks (which in turn cause increased shock sensitivity). Migration of the exudated liquid into the fuze screw thread can form fire channels, increasing the risk of accidental detonation. Fuze malfunction can also result from the liquid migrating into the fuze mechanism. Calcium silicate is mixed with TNT to mitigate the tendency towards exudation.
