Can I assume that Black walnut is a somewhat more expensive wood than
what we have as "walnut" here?

I turned quite a bit of walnut from a neighbors tree last month and no
irritations or problems with it, except for minor hand staining... and
that was mostly from the inner bark..

My guess is that what I has was "English walnut", but how would I
identify Black walnut??


Black walnut is the native J nigra. Almost any walnut reproducing in the
wild in the US should be J nigra.

It is rich in extractives in the heartwood, including some nasty stuff that
can cause horses hoof problems. Also has a nut which has less overall meat,
and a harder, packed shell than the "English" J regia. English walnut
scions are normally grafted onto the more hardy black walnut roots in
orchards.

So, if you got orchard wood, might be different than the wild stuff.
