Collapsible Cauldron

A collapsible cauldron is a cauldron which is presumably capable of being folded for portability or easy storage. The cauldron shop in Diagon Alley carried this type of cauldron. Bruno Schmidt, a six-year-old boy from Germany, killed an Erkling with a collapsible cauldron belonging to his father, thereby saving his own life.
