Cryogenic treatment of brass instruments?
On another newsgroup, the subject of cryogenic treatment of brass
instruments came up, with the claim that it was "snake oil" and offered no improvement. On a trumpet newsgroup, I've seen postings by people who claimed that their horns sounded much better after cryogenic treatment. The general claim was that the treatment aligned the molecules and relieved internal stresses in the metal, or something like that. Perhaps you metal guys have some insight on cryogenic treatment as it pertains to brass, and brass instruments in particular. Any basis in fact, or pure BS? -- Jedd Haas - Artist http://www.gallerytungsten.com http://www.epsno.com |
