Somebody told me one time that cork grease was just a mixture of

Lanolin (USP) is a strong yellow-brown, and the cork grease that I
used to buy at the music store is pure milky white. So I don't think
they are related. Also the two items feel completely different if you
rub them between your fingers.

But I was struck by insomnia tonight, and so I got out my lab
thermometer and did my best to determine the temperature vs. viscosity
curve of each. Years ago, I had a complete viscosimeter setup, but now
all I have is the thermometer. So please take my results with a grain
of salt:

Lanolin changes from a mushy paste to a pourable liquid (slow pour)
at about 92 degrees F. The left-over tube of 'music-store-grease'
that I had sitting on my shelf does the same at about 100 degrees F.

So by this standard, I should like the 'music-store-grease' better
than the lanolin.

Conceivably you can package 'music-store-grease' in lip balm
dispensers and ship it into a hot (95 degree F.) environment --- whereas
you could not do the same with lanolin. [90 degrees is a scorcher
where I live.]

I suppose psychology counts for more than physical science in this
case. The lanolin feels better and more manageable to me, even though
it gets soft at lower temperatures.

Cheers, and I apologize for having made a mis-statement,
Bill
