This local zinc was used in speltering and allowed greater control over the zinc content of brass and the production of high-zinc copper alloys which would have been difficult or impossible to produce using cementation, for use in expensive objects such as scientific instruments, clocks, brass buttons and costume jewellery. However Champion continued to use the cheaper calamine cementation method to produce lower-zinc brass and the archaeological remains of bee-hive shaped cementation furnaces have been identified at his works
Industrial metal have since patched things up and have even performed on stage together. Industrial metal suffered a critical backlash at the turn of the millennium. In an April 2000 review for the "Chicago Sun Times", Jim DeRogatis dismissed Nine Inch Nails' new music as a "generic brand of industrial thrash" and accused Ministry of repeating an act that "was old by 1992".
