We have heated brass up with a blowtorch, and it never does get very active, even though brass will give small, occasional bubbles if dunked in peroxide.At 08:11 PM 10/29/2002 -0800, Donald Qualls wrote:Say, has anyone tested copper or bronze as a high temperature catalyst? Melting point significantly higher than silver, 1083 C for pure copper; bronzes can be had with either higher or lower melting points. The high corrosion resistance of these metals suggests a tenacious oxide coating, and copper's reactivity is similar to that of silver in many ways -- but it costs about 1/10 as much.
