Potage's Cauldron Shop is the first shop encountered when entering the north side of Diagon Alley from the Leaky Cauldron. Selling all types of cauldrons, displaying them in a stack outside the shop, under a sign which read: "Cauldrons - All Sizes - Copper, Brass, Pewter, Silver - Self-Stirring - Collapsible". It is owned by Madam Potage and rumour has it there's a branch of the shop located in Knockturn Alley.
