[Trombone-l] Lubricant details

[Dennis Clason]

Reports are that the white component of SoM is a dilute soap solution.  
I've read that the soap is derived from whale oils, but I don't think I 
lend that any credence.  It's just too easy to get a more consistent 
source of light oil to saponify.  The clear component is a lightweight 
silicone oil.

A green/blue residue is almost certainly a copper compound.  There are 
no acids in SoM, so perhaps your saliva is somewhat acidic?  Or your 
drinking water?  I think I'd try using distilled (or RO purified, 
whatever) water on the slide and see if that fixes the issue.

Al Cass and Holton valve oils are deodorized kerosene.

Synthetics like Reka and Alisyn are silicone oils.  The exact 
formulations on all of them are trade secrets.  You can get some clues 
as to what is in them with a gas chromatograph and mass spectrometer.
