I cannot tell a lie. I added to the thread title so I don't get a lot of messages asking, "Why isn't this thread in the BS section"?

This page (click) has information on cryogenic treatment of metals. It all sounds very credible, but I don't know what to believe...
This very informative page says a piano with cryogenically treated strings, didn't need tuning after 2-1/2 years.
