This exhibition explored the links between industry in the West Midlands and the commercial gains of slavery. Wolverhampton's role as a manufacturer of iron was crucial to the economy of slavery, as implements of restraint and punishment were needed to repress those who fought their enslavement. The exhibition emerged from a collaboration between photographer Vanley Burke and blacksmith Lofty Wright. They re-created 40 cast iron instruments used in the slave trade: forked wooden yokes that controlled captives; irons, muzzles and braces that were used to constrain and as punishment. Each of the metal items was symbolically coated in sugar.
