Patrick, No documentation. The only "magnification" is my fungal theory, magnified on this list, as is my scientific prowess.... I imagine that by now you caught Jim H's tactful, slightly gentle (priceless) note. If I had been posting on this list for more than a couple of months I would have gotten the flames; as it is, I am left twisting in the wind. Since no one has yet posted in my defense (anyone??) I think me and my theory are alone. I have been spouting the fungal theory for longer than I care to admit, for reasons explained in my response to Jim. No experimental research here, just my own Higher Authorities, I guess. I guess the Steinway green crud is only chemical (verdigris), not also biological (green plants). The heat treatment seemed to back up the theory. Still seems plausible. Thanks for your posts. (Hasn't ANYONE heard about this theory before?) OK, I'll shutup till next time. Anyone? Bill Shull << Dear Bill: Are you certain that "verdiris" is "the residue of fungus"? What fungus? Can you find spores under magnification? Did you determine it is a fungus, or were you told that by An Important Authority? I always *thought* it was a chemical interaction between the paraffin, acids remaining in the felt, and the center pins. But that was because "someone told me so" ... Any documentation? TIA, Patrick Draine >>
