Re: [MedievalSawdust] Re: A Wood finish
- View SourceThe bottom line on cutting boards is, both wood and plastic are safe if
you keep them clean and keep them dry - and neither are safe if you do
not. The differences between the two materials are interesting but
negligible in terms of personal use. (Commercial food preparation use
patterns are very different, the materials have less chance to dry out
as they are in use more continuously, so bacteria populations can build
Wash well, wipe with vinegar, keep dry between uses, and you'll be safe
with either material.
Now back to the original question - as others noted, no finish at all is
probably best for this application, but in practice all modern finishes
are safe when fully cured. Bob Flexner has been trying for years to
combat the persistent belief that wood finishes are toxic. They are
not. But if you don't believe him, use shellac - it is in fact
food-safe, used to coat pills, among other things.

- View SourceBob Flexner, author of "Understanding Wood Finishing", wrote an
article for the Spring 2008 American Woodturner. He says that all the
"Salad Bowl Finishes", etc., are simply alkyd varnishes thinned with
mineral spirits - "wiping varnishes." They contain the same driers as
any other varnish and are no more or less safe. All the driers used
in varnish and drying oils like BLO are approved by the FDA (Bob says
to google "21CFR175.300" and click on the top link). His contention
is that all finishes - varnish, drying oils, lacquer, etc. are
"food-safe" after they have fully cured.
Given that information, what finish would handle rough use over time
best? A surface finish, like poly, lays on top of the wood, and
provides good protection from water, drool, etc. An oil like BLO
soaks in, but offers little protection at the surface. I'd go with
what works best for you on other projects.
