A hand-painted cylindrical pot hand with a space in the center with the name of the substance it contained: "Manna".
Manna is a sweet and gummy substance that flows from plants such as ash trees and is used as a purgative. The pot may still contain traces of the product.
This was acquired by Tomàs Balvey i Paré in 1927 from a potter in Barcelona, along with the rest of the nearly two hundred pots. They were still in use until 1943, when his grandson, Tomàs Balvey i Bas, closed the pharmacy.
