glaze 'copyrights' (was walking on eggshells)

Much of the discussion on this topic has repeated
the misconception that glazes are protected by
copyrights. Lists of ingredients, as well as most
process descriptions, are *not* protected by
copyright law, which was drafted to protect creative

Glaze formulas can, in principle, be protected by
patent law. In practice, I think this would be very
difficult, because of existing "prior art."

I don't want to be pedantic about this, but I think it's
important for ClayArters to understand that they
are not getting any legal protection when the put a
copyright notice on a glaze formula (even if that formula
is included in a copyrighted work).

We as individuals can choose to respect the wishes of
the authors (which I do) - but please let's be clear that
this is an ethical decision, not a legal one.
