Hi John ,
you have a very dense , nice example of bone that makes up your wrongko
whereas the example we are discussing is of much poorer quality .
I wonder does yours have any scent at all and which part of the skeleton it was from ?
I know that here we used to leave the pieces (vertebrae) outside on the roof of a shed or garage for a few years to 'sweeten' them as they were so oily .
Possibly the bone is boiled over there to get the oil out .
A gateway made from jawbones a couple of miles away from my house .
