We were still using whale oil for quenching steel in 1995 when I was
doing research at Leeds University. It was old stock, of course, but
they had enough to last for many more decades.

As for rapeseed oil, I am pretty sure that is what it is sold as in
the UK, rather than being rebranded as Canola. What the actual oil is,
I have no idea.
