Hi Dinah,
You ask below,
<"and there was a statement that their unglazed clay body doesn't
release lead like others might -- along that line. What's this all
about then? I've never ever made pots -- yet - which are unglazed for
domestic use. What should one be aware of when one makes unglazed
ware. Thanks.">
I think that we need to keep in mind that people are sentient, but
almost never rational. Lead is scary alright, just think of all that
old leaded gasoline.
When a potential customer asks me about lead, and if there is any in
my pottery I usually reply something like this:
"Well, though lead glazes are possibly dangerous for the person who
eats out of the pottery, they are much more hazardous for the potter
who is making the stuff, getting powdered lead on their hands and
clothing and breathing the airborne lead dust. So I don't use the
stuff. Besides, if you make stoneware and porcelain pottery that is
fired above 2300F, there is no use for lead anyway. It's a low
temperature flux, not useful at high fire temperatures. So relax and
buy that teapot."
Also, I've never heard of lead being used in a clay body, but
sometimes they put barium in earthenware bodies to cure scumming. I
never scrub the inside of my unglazed "morning" teapot. It's a fake
bizen clay fired to cone 11 or so. It makes tea real fine, every
morning.
