Cordia rosewood

Postby John Willman » Thu Jan 11, 2018 4:03 pm

I have some cordia rosewood, also known as Gamboge, which I bought for woodwinds. When the rec order joints are left for some time a grey powder develops on the surface and especially on the bore. I am not sure if it is a reaction to the linseed oil used, or quite what it is. Any observations would be welcome. Thanks.
John.

John,

If you have access to or know someone with access, try getting a look under a microscope.
You brought back fond memories of a mystery the forum chased back when we were all much younger...

That was an interesting thread.

my favorite Mr. Tweedy quote is :"I know what you mean, but the proof is in the hyphae. "

Many thanks for leading me to the threads. I shall have to try ways of dealing with it, although it does take a long time to re-form when removed. It does look crystaline, and fits in with the second 2009 thread. I suppose the real worry is whether it is harmful in some way.
