Miroslava Randova asked a number of questions about functional raku. I
will be doing some raku for the first time next semester, and I've been
told that raku cannot be used for food. Are there food safe raku
glazes? If so, are any of them available commercially? For a lot of
reasons - most of them health related - I do my best to avoid making
clay or glazes from scratch.

Thank for the info on my last raku question and for the help I'll get
on this question.

Deb: I don't know about functional raku, but I LOVE your tutu -- and your
blog. You are truly a "renaissance" woman. Barbara

I will emphatically state no, there are not any food safe raku
glazes, at least not of the "Western" raku style. I believe, for a
number of reasons that have been discussed at length, that anyone who
says that raku is "food safe", at least by contemporary standards, is
misinformed at best. Anyone who would indicate this is probably also
inclined to have you believe that raku glazes are somehow stable or
archival in nature. If you want a definitive primer on raku glazes
follow the link to the article written by Tom Buck. Pay attention to
what he has to say. He is a retired chemical engineer who knows of what
he speaks.
Here's the link.....http://digitalfire.com/education/glaze/buckraku.htm

Hope this helps
