Ron, I went back through about a years work of Ceramic monthly and a few
Claytimes. I find it curious that so many of the "recipes" do not make any
reference as to whether or not it is food safe. There may be individual
articles on handling the raw materials and safely protecting the potter,
yet, it really surprised me that so many glaze mixes were silent on the
safety issue. Now, as was stated before, if a glaze is developed by a
potter for clearly non-functional ware, maybe there doesn't need to be the
caveat about safety. But, when you realize the readers may be using the
glazes on functional ware, it gets a little frightening.
I have only been mixing glazes for a year, and it is absolutely frightening
how many recipes I have just printed off or torn out of magazines and until
recently had no idea how toxic some of them were.
It would be nice if glazes have made it through the Hale/Hesselberth process
if that could become part of the glaze recipe, just like the cone #.

Just ran across this - trying to catch up on my email.
Yes - and I think there are a few reasons for this.
1. Safety is becoming a larger issue - and I think rightly so.
2. Most of those posted glazes are from potters who simply don't know
enough about glazes to be aware of any short comings - and most couldn't
care less. It's still happening and even from those who should know better.
3. It is difficult to tell - even when using calculation software - if
glazes are safe without having them tested - even difficult to know then
because we are not sure what is safe.
My approach is - use only safe oxides in liner glazes and keep the
colourants out or at least to a minimum.

When I was a lot, oh a lot, younger I remember a B movie at the cinema that
featured an Australian/ NZ Potter who supported himself in truly rustic
style. Big Pots, wood fired, wheel thrown, and significantly an amazing
little train that dragged clay out of the hills to his workshop.
Any distant memories? someone did mention a name in a conversation but it
disappeared into a beer glass.

That New Zealand potter, Barry Brickell, has a web site with pictures of his
train, but not his pots.:-( Here's the url:

In the 80's there was a wonderful tv show called "This is New Zealand" and
they did some wonderful profiles on their craftspeople.
Enjoy!

Kia Ora!
This potter if it is the one you are talking about lives
still in the Coromandel in the North Island of New Zealand. Definitely
not Australia. His name is Barry Brickell (hope I got the spelling
right) and he used to hold a potter's "Do" every year when potters from
all over the country would collect and have a sort of get together. I
was never able to attend one of these to my regret. They were famous.
Amazing pottery!!
