The special exhibition "Mortars" explores the question of why there are so many different mortars and how they were used. The recipe is often decisive, as whether a stone or bronze mortar is used usually depends on what is to be processed.
Mortars made of bronze or brass were traditionally cast like bells or guns. The exhibition is the first to present the Roth and Weitnauer foundry families, who lived in Basel for a long time and whose craft shaped the Basel area for centuries.
