I am starting up my pottery studio after a long hiatus and find myself ready
to start glaze testing again. I have been sifting through the archives and
really can't find any number of clear low fire glazes that seem to meet food
safety basics. I just got J. Hesselberth's glaze software (as a gift from
my thoughtful husband)and whenever I type in a typical low fire glaze (I
have used in the past) it just doesn't meet the general standards. I know
there are concerns in the minds of some that low fire isn't food safe at all
but that is not the discussion I hope to review here. I would appreciate a
few glazes that I can start testing or one that others have already tested
in some way that I can try out. THANKS!

In fact, there are surprisingly few that have even a basic verbal
description of results from someone who has used them. The Glaze
Database will welcome any results from Robin's search.

Hi Robin,
You can take a look at this article:
"Are Your Glazes Food Safe or are They Leachable?"

Thanks Helen!
Phew, I was just about to despair!
Those articles were very interesting and the ^06-04 base glaze recipe and
discussion about how to alter it to fit a clay body was very informative, a
great place to start. I am using Tucker's red majolica body which is
described by them as being stronger than other low fire reds...I wonder if
it is due to a finer particle size? I would still like to hear from anyone
else who might have clear low fire liner glazes they have had good results
with.

Hi,
I think it can be done using frits - if you are willing to do some
experimenting I can get you started - I need to know what spars you have or
can get and if you can get frits 3134 and 3124.
I need to know where you are as well because you will need to send some
samples off to have them lab tested.
Ron Roy.
