I know that you wanted to stem off this discussion of the "badness" of
putting a crazing glaze on functional work, but Chris is right. I had
to remove specialty glazes from the City studio, because I couldn't get
people to understand that just because they wouldn't use that pot that
way had nothing to do with what someone else might do with it after it
left their possession. You cannot control how or what some one will use
your pots for. But in our society you can and will be held liable for
what you make and sell (or give).

Oh, we didn't know you were going to destroy the stuff after using it once.

William -

Sorry to be a nag - but if you know the 'supposed' health risks of a
faulty glaze -( which is essentially what a crackled glaze is ) why on earth
are you testing this stuff for dinnerware ??? You even mention using inks or
stains to add black color to the unglazed areas. I suppose the risks of these
saturated black stains are only rumors as well.

What lucky person gets to put your plates in the dishwasher and never
see the black again?? Or better yet use it with sweet & sour pork and have an
orange background instead. Or leave them unwashed overnight and get plates
that have leached and changed color.

Using proper glazes is not just a boring thing that unimaginative
potters do. We have very active imaginations that at their wildest cannot
even get close to the strange things our customers will do with our properly
glazed wares.... let alone a non-functional dinnerware set.

Hi All,
Just got done reading all the posts and I have a couple of questions. I
am doing my very first firing tommorow and I was wondering what glazes are
safe? I mean, I dont mix up my own glaze(yet) but before I go giving a
coffee cup to someone I thought it might be worth knowing. Also is all clay
ok to use as functional forms? I use a red clay with grog, mixed with a
white clay. Supposed to be fired to a cone 6. Is this ok???
Jennifer- very nervous and praying 1 peice makes it through the maiden
firing-Ohio

The reason is that I know exactly how, when, where and why the dinner ware
will be used. I also take it by your post that you don't have a cone 6
crackle glaze. Also, the chances of using a piece of dinner ware once and
dropping dead because of it are less than that of getting struck by
lightening while you dance a jig in a fairy ring by the light of a blue
moon! I mean look at how long people had their Fiesta Ware in a radioactive
color and not of them dropped dead on the first, second or even third use.

"I mean look at how long people had their Fiesta Ware in a radioactive color

Well, lets set that up as the new standard for quality control. No death, no
problem.

I will again apologize for ruining the fun. I happen to take quality
very seriously. Yes, I have Cone 6 crackle glazes that I have developed,
tested and used ... but I would never use them on functional
ware...especially not for myself or my family.

For Jennifer who was interested in learning more about glaze safety
check out the site of John Hesselberth who has been testing and providing us
with his results. We have all profited from his hard work :

Dear William,
Cone 6 crackle glaze is not one I have tried for, however, I have gotten some!
What some will call a fault, others seek as an effect.

My only offer is to say that I have experienced major crackling, which I
found to be a fault, so I called crazing, when the clay and glaze did not
fit. Mostly this occured with clear glazes. As soon as I colored them,
they melted smooth.

Not much, but a thread maybe to experiement with.
Best regards, Alisa

There is much handmade dinnerware with crackled glaze photographed for the
glossy pages of food magazines these days. And many many people are
influenced and 'educated' by these beautiful pictures. This ware is used
both to sell products and illustrate artlcles. It would be extremely
productive if the new council could 'educate' the designers and publishers
in the serious error of their ways! This is not said 'tongue in
cheek', and I imagine many potters would find it hard to turn down a
commission that gave them this much exposure. Lori Pierce in New Port
