The process of forming or developing a hard outer layer or crust on a surface.
From the verb 'crust' plus '-ing' (present participle). Derives from Latin 'crusta' meaning a hard layer. Originally described the natural geological or culinary processes of hardening.
Wound crusting is actually your body's built-in bandage system—it works so well that some modern medical dressings try to mimic the exact chemistry of what your body naturally creates!
