- Briefly, the washed hair was digested in an alkaline solution, complexed by cysteine, urea, and cupric ion, then acidified with sulfuric acid.
- The oxidizing fluxes usually include cupric oxide or manganese dioxide, which decompose at copper alloy melting temperatures to generate the oxygen required.
Origin
Late 18th century: from late Latin cuprum 'copper' + -ic.
