Jack,
Thanks for the note and the astute observation.
I have always had some information, but I also never believe we know all the answers, so I guess I will always be trialling and testing.
Been very ill this year, and the light came on to make me realise none of us are immortal. What is the point of anyone taking anything to the grave?
The clever bit is to impart your knowledge before you pop your clogs.
I have always held the belief that anyone who depends on the few dollars a 'secret' recipe of stock oil will bring is pretty desperate to make a dime.
I personally like to admire a piece of well done craftsmanship.
It is not the oils that are the secret it is the application.
